Corte-Clean® has been PROVEN for CLEANING COMPOSITE DECKS, DOCKS & FENCES for over a DECADE, especially when MULTIPLE OTHER PRODUCTS ultimately FAIL, as so many of our NEW CUSTOMERS have experienced. More importantly, it has been PROVEN to KEEP THEM CLEAN, generally at a MUCH LOWER COST.

2017 Trex® Transcend® PVC “CAPPED” decking with recycled wood & plastic core, which has been Corte-Cleaned® (ABOVE) Testimonial 4.7.2018

 

I have a trex deck in a new construction home with 2 dogs. The grass just got installed last year along with the deck. This year the deck was so muddy and dirty I thought it would never look like it did last year. I followed the instructions exactly as it was stated and the deck looks brand new. I cannot believe the difference. I did have to rinse it very well to get all of the white residue off. I wish I took a before picture. The results are amazing. I will continue to use the product year after year.

Why choose Corte*Clean® to clean an expensive composite deck, dock or fence?

CORTE*CLEAN® is the proven solution for cleaning all common staining issues caused by mold & mildew, black spots, sap, grease, oil, barbecue, tannin, leaf, pine needle, chalk, berries, blood, sunscreen, olive oil, citronella candle oil, peanut butter, red wine, pet food & waste, hard water, grass, ground in dirt, clay, brick, flower pot, rust, grime, green slime & most other stains that are deep set or below the surface & can deeply root or saturate into the porous surfaces of most composites.

CORTE-CLEAN_Composite-Deck-Cleaner_BBQ_BEFORE
CORTE-CLEAN_Composite-Deck-Cleaner_BBQ_AFTER

Corte*Clean® is designed to clean plastic & wood composites, especially those made from dirty recycled plastic, which have been found to grow molds from within, & dirty recycled wood fibers, to eliminate what is known as “tannin bleeding”, or the food from which molds, mildews, lichens, mosses & algae’s can feed. Corte*Clean® then soaks into the pours of most composites & continues to clean, any time it receives moisture, generally keeping composites clean for longer periods of time, until thoroughly rinsed. Proactively applying Corte*Clean®, at the reduced “routine cleaning” Corte*Clean® strength, before composites receive moisture, fungus spores hatch, germinate, colonize & stains occur, or deeply saturate, is proven to generally cost less money, time & labor, to keep composites clean. You won’t find a more proven, cost effective, single product, that cleans all common stains from expensive composites, & keeps them clean.

CORTE-CLEAN_Composite-Deck-Cleaner_MOLD_BEFORE
CORTE-CLEAN_Composite-Deck-Cleaner_MOLD_AFTER

Corte*Clean® does not have all the additional costs, risks & time related to expensively purchasing & laboriously applying multiple other perceived inexpensive non-compatible cleaning products, to clean specific stains.  You won’t need to purchase & use one or more products for mold & mildew stains, lichen & moss stains or algae stains, especially those products that claim to clean and/or prevent, but generally take weeks or months to work; if at all. A 2nd product to clean corrosion stains from rust, which corrosive to structural metal cleaning products cause, or tannin stains, from leaves, pine needles & other organic debris. A 3rd product for grease & oil, or multiple other specialty products to clean specific oil stains & spotting. You won’t need to purchase & apply expensive products that claim to “Keep Mold From Coming Back” by sealing composites, which can exacerbate cleaning issues, or expensive generally laborious products to remove sealers when they begin to generally rapidly weather off, crack & look ugly. The information on this web site should be carefully considered. It will help guide you to why Corte*Clean® is the single, safest, cost effective, eco responsible, biodegradable, non-corrosive to structural metal product for cleaning & keeping long lasting composite decks, docks, & fences clean.

Getting ready to Corte Clean® Trex®

Cleaning wood & plastic porous composites & keeping them that way generally requires different cleaning chemicals or products than solid wood or non-porous solid plastic vinyl. You wouldn’t use diesel fuel in gas powered motor, unless you wanted to expensively cause problems. The same is generally true when using products designed to clean only wood, and/or multiple other general purpose cleaners to clean common wood & plastic porous composites.

Corte Clean® working (left of photo) to clean heavily common black mold stained Trex®

Generally black or green molds (moulds), are common growing into composites, while white colored mildews, a mold subspecies, is not. Mildew is NOT generally the difficult to remove, common pesky black mold leopard spots composite owners most commonly experience rooting into their composites, generally after a mold spore or seed in the air lands on composites & receives moisture. Black mold stains generally start out looking about the size of a dime or nickel when they appear. Composite owners often have no idea what it is?

Trex® when black mold generally first appears to spot, after mold spores or seeds, in the air, land on composites, receive moisture, hatch, root in & feed from the dirty recycled plastic and/or wood fiber “tannins” of which most composites are made.

Chemical manufacturers have done a tremendous job of misleading people into believing all molds are mildews, & green molds, mosses or lichens are algae’s! They do this so they can sell chlorine bleach or other sodium hypochlorite biocide based products, generally originally designed & intended to clean generally only “wood” of “mildew” & “algae”, while preying on uneducated peoples beliefs. Composite owners then purchase & use these products believing they are the right product to remediate; or clean & keep composites clean, of unsightly resilient common black & green molds from porous plastic & wood composites. Unfortunately, most retailers & composite manufacturers have naively fallen for, been sold or actively participated in misleading the general public as it relates to the proper cleaning chemicals or products for cleaning common black & green molds from composites. Why do you think this is?

Correct Deck® boards becoming infested with mold as it germinates into colonies after the use of scientifically unproven sodium hypochlorite.

Most deck cleaners were originally designed & intended to clean specifically only “wood”, of “white” colored “mildew”, for which a “mildew stain remover”, which contains “sodium hypochlorite”, the active biocide in chlorine bleach, is generally accepted as being effective for this specific species of mold, however this is HIGHLY scientifically controversial! Those that have experienced green molds, mosses, lichens or algae’s growing on and/or into composites are almost always a sign of neglect or improper care, such as only using a brush and/or power washer, and/or the use of the wrong cleaning chemical products, especially on a routine basis. Like mildews, lichens, which generally arise from algae’s, which almost always only live in water, such as an untreated swimming pool, for which sodium hypochlorite-based chlorine is/has been commonly used to treat, are incredibly rare growing on and/or into composites. The general exception would be composites that are usually submerged, and/or not properly installed, or gapped, to allow for proper water drainage. This can result in shallow water pooling on composites, resulting in algae, then lichens.

CORTE-CLEAN_CORRECT-DECK_BEFORE_MOLD-LICHEN-MOSS

Correct Deck® colonized with green mold, commonly confused with algae, which generally only grows when submerged “IN” water, such as a pool, or lichens which arise from algae.

Sodium hypochlorite-based deck cleaning products, that were originally designed to clean “wood”, of “mildew”, should never be used to clean longer lasting composites, of the common black & green molds, lichens, mosses or algae’s, unless one generally wants these pesky stains to almost always rapidly return, and/or exacerbate the problem, while causing expensive & potentially dangerous to remove rust stains around screws or nails in composites. Rust stains then generally require another generally corrosive, laborious, non-compatible expensive chemical to remove. Unfortunately, unscrupulous chemical manufacturers have added “cleans composite decking”, to existing products, in an attempt to sell more product & increase profits while preying on uneducated people’s beliefs.

Where the BBQ mat was blocking mold spores & moisture, notice no black stains. 

Most composite owners that initially choose to use “sodium hypochlorite” based products, to clean common black & green molds, often at the recommendation of retailers or composite manufactures, initially think they work great, the first several times these products are routinely used! Don’t be fooled, or surprised, when black molds are no longer bleached out, or these and other funguses generally rapidly return when composites receive moisture! The more concerning issue is the irreversible corrosion corrosive cleaning chemicals cause to structural metal supporting & holding together most composites!

Trex® composite decking previously cleaned with sodium hypochlorite, resulting in other fungus growth, which is feeding from the tannins, from the exposed wood fibers, of which this composite material is partially made.

The use of sodium hypochlorite-based cleaning products are not generally designed to clean the underlying issues from which most composites are made. These products generally temporarily chlorine bleach out common black & green mold stains, but do not remove them. This is because sodium hypochlorite is not scientifically proven to kill or remove molds, making the molds & other funguses more resistant to the chlorine in these products, while watering the molds, generally allowing these funguses to root deeper into composites, resulting in it almost always costing more time, labor & money to initially properly thoroughly Corte-Clean® in the future.  The previous use of sodium hypochlorite almost always results in sterilizing everything but the molds, resulting in the perfect environment for the molds to thrive, form colonies & infest composites, especially in warm humid and/or routine moisture sunny conditions! The molds then generally rapidly return, which has plagued composite owners & manufacturers, generally resulting in the needed to expensively purchase & laboriously use sodium hypochlorite-based products more & more frequently, costing more & more time, labor & money? Who do you think profits from this?

Mold colonized Trex®, from the routine “Spring and Fall” use of “sodium hypochlorite” & partially Corte-Cleaned®. Deck is wet, with water to magnify stains.

Wood deck cleaning products that contain sodium hypochlorite don’t generally clean the recycled wood, from which most composites are partially made, of tannins, to eliminate what is known as “tannin bleeding” in the composite decking industry, or the food from which funguses can feed. They chlorine bleach out the redwood, cedar, teak, mahogany, etc. tannin colors, or the natural beauty from wood, while destroying the wood lignin. Wood deck owners generally wish to restore these beautiful tannin pigments, not just bleach them.

Corte-Clean® cleaning mold stains & tannins from the oak wood fiber of which this Lowe’s® ChoiceDek® is partially made. Failure to thoroughly Corte-Clean® composites, to eliminate mold & other fungus stains, & tannin bleeding, generally results in mold stains re-occurring sooner, rather than later. Do not cut corners, by ignoring all Corte-Clean® product label directions, or you are likely wasting your time & money with this serious industry wide known problem.

Once wood has been chlorine bleached with sodium hypochlorite-based products, chemical manufacturers & retailers then generally sell a “wood brightener”, which contains “oxalic acid” in an attempt to restore the bleached color of the tannin pigments & remove rust and other stains. Therefore, using a wood brightener product originally designed to restore wood tannin pigments, should not be used in an attempt to clean composites of wood “tannin bleeding”. Oxalic acid-based cleaning products generally do the exact opposite of what is necessary to keep composites clean, as it relates to all funguses while being non-compatible with sodium hypochlorite & can also be corrosive to metal.

Tannin bleeding from the wood of which this partially Corte-Cleaned® TimberTech® composite deck is made. It generally takes two (2), or more, Corte-Clean® applications to eliminate tannin bleeding, from composites that haven’t been previously Corte-Cleaned, depending on the type of wood composites are made from. Hardwoods, such as oak, maple, etc. generally require more applications than softwoods, due to the wood being more dense with tannins, which can be more food for funguses to feed.

Composites are generally made from Polypropylene (PP), Polyethylene (PE) or Polyvinyl Chloride (PVC) plastic & wood. The newer generation of composites, commonly known as “Capped Composites” are generally made from a core of PE plastic & wood, with an exterior wrap or “cap” of PVC plastic. Some composites are made with recycled plastics, most commonly PE plastic, that commonly came from plastic bags, shrink wrap, milk jugs, food packaging, etc. Unfortunately, the recycled plastic commonly used to make composites was not generally thoroughly cleaned. These dirty plastics were likely going to grow funguses that consume rotting organic matter on the dirty plastic when it receives moisture, as this is what funguses do to naturally recycle dead organic matter. The plastic is then generally mixed with recycled wood, another dead organic material from which funguses can feed, & extruded into composites. This can make for the perfect environment for funguses to germinate & colonizes, or spread, when it receives moisture, is neglected or improperly cleaned.

Milk jugs, shrink wrap, cheese wrappers, plastic bags & other dirty plastics commonly used to make composites.

Unfortunately, composite manufacturers didn’t generally clean the recycled wood fibers of tannins, to eliminate “tannin bleeding”, prior to making composite decking & fencing products. Failure to clean dirty recycled plastics generally resulted in molds growing from the dirty recycled plastic & feeding from the wood fiber “tannins” when the composites receive moisture, resulting in the perfect for these funguses to thrive! This explains why some composite owners have experienced molds growing “IN” only one composite board, & none surrounding it, even in the newer capped composites.

Recycled hardwood fibers commonly mixed with plastic to make composites.

Composites made from virgin plastic or non-recycled plastic & wood, mold growth from within composite boards is less common, but still can occur if resilient mold spores, or seeds, are in the wood, before being extruded into composites. Unfortunately, composite manufacturer extruders can’t generally get hot enough to kill or sterilize the extremely resilient spores, as the dirty plastic & tannin laden wood would generally catch fire first. It is our understanding that heating the wood & plastic, in an attempt to sterilize these materials of molds, in an attempt to eliminate this problem, before extruding these materials into products has burned down at least one composite manufacturing plant.

Corte Clean Cleaning Mold From ChoiceDek
ChoiceDek® made with oak hardwood where a liquid dishwashing soap & sodium hypochlorite was recommended & routinely used until completely mold colonized. Corte Clean® working to clean this heavily mold stained composite deck.

Composite cleaning issues, specifically those caused by rapidly returning molds, generally due to neglect or improper cleaning chemical product recommendations, is a serious industry wide known problem. This is proven especially true for composites located in humid or moist environments, that receive routine moisture, are neglected, only power washed, or where scientifically unproven products have been used in an attempt to clean molds, until it no longer bleaches out the fungus stains & color of composites. Unfortunately, many composite owners have experienced this, which has tarnished the overall reputation of the composite decking industry.

Failure to review the Corte*Clean® websites, or at least watch the demo video & carefully read, comprehend & follow its label directions, will likely result in you being dissatisfied with our proven product, as unfortunately some customers experience. You have likely already tried using multiple other perceived inexpensive cleaning products, wasting much valuable time & money while making cleaning problems generally cost more time & money to Corte*Clean®!  Do not cut corners or get cheap if you choose Corte*Clean®, as you have likely already been dealing with a rapidly returning serious problem, wasting much time & money, resulting in you finding Corte*Clean® & taking the time to read this to understand the problem & properly clean an expensive composite deck!

The following information will alert composite owners to what is referred to as “The Chlorine Bleach Scam” in the composite decking industry with “sodium hypochlorite” based products!

Mold infested TimberTech® Composite deck from years of routine sodium hypochlorite, till it had little if any chlorine bleaching effect with common black mold, resulting in the molds no longer spotting, but completely colonizing the entire composite boards. This is an example of a worst-case scenario which generally costs more time & money to thoroughly Corte-Clean®, as the mold has likely rooted through out the plastic & is feeding off the wood fiber tannins!

There is good scientific reason why, the Occupational Safety & Health Administration, OSHA, (CLICK HERE), states {Under: “Use of Biocides”} “The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation”.  The active “biocide” in “chlorine bleach” is “sodium hypochlorite”, which has been commonly recommended, by all known composite manufacturers, generally, under “Care & Cleaning” for “Mold & Mildew”, be used on a routine “Spring and Fall” basis. They have done this even though a scientific study was conducted by Oregon State University (CLICK HERE) titled “Ability of bleach and other biocide treatments to remove and prevent mold…(2004, April)”, has proven the specific “biocide”, “sodium hypochlorite” to be ineffective in mold remediation, or cleaning & keeping clean of mold, from the “wood”, of which most composites are partially made, by concluding “Increasing bleach concentrations from 2.5 up to 20 percent [sodium hypochlorite] solution had no effect on the appearance of the wood following the wash treatment, nor did such treatments completely eliminate fungi from the wood surface. The chemical mold prevention treatments tested were not effective in sterilizing the wood, nor did they improve the visual appearance.”! This science is especially true with composite manufacturers that use recycled hardwoods, such as “oak”, “maple”, etc., as these species are notorious for supporting fungi in composites due to the structural cellulose being denser with tannins that can feed molds. Some composite manufacturers have even chosen to recommended products that contain “sodium hypochlorite” & polluting “phosphates”, or “phosphoric acid” which act like Miracle-Grow® for helping molds generally rapidly return, especially algae’s in water!  Composite & cleaning chemical manufacturers have chosen to ignore this irrefutable, indisputable, mold remediation science, almost always resulting in rapidly returning molds, which includes mildews, when sodium hypochlorite is routinely used. Do you think it is smart to ignore science & OSHA, especially as an employee, when recommending, selling or using products for cleaning mold from composites?

Mold leopard spotted Lowe’s® ChoiceDek® made with oak hardwood.

Most composite deck owners trusted composite manufacturer cleaning chemical recommendations, for cleaning “mold and mildew” that contain “sodium hypochlorite”, because it generally appears to rapidly bleach out these & other stains, the first several times used. Unfortunately, this generally chlorine bleaches the color of almost all composites, especially those made from recycled plastics, which were generally colored after the plastic was made, beyond what most composite manufacturers disclosed under “weathering”, or bleaching/fading, especially when using these products undiluted, in direct sunlight, when people generally clean decks, and/or when using products designed to clean wood, or that contain higher sodium hypochlorite strengths and/or volatile surfactants. This generally lead to the 2nd biggest complaint in the composite industry, excessive color fade by chlorine bleaching, which has led to much contention between retailers, composite manufacturers & owners that have recommended or sold these products.

Trex® where sodium hypochlorite was routinely used until mold infested. Sodium hypochlorite composites generally look clean, free of mold or bleached when dry. Don’t be fooled! Notice how the area wet, with water, magnifies the black molds. The mold will very likely rapidly return with vengeance when it receives moisture, germinates, continues to colonize throughout every composite board, as it blooms & spreads!

When sodium hypochlorite-based products no longer appear to bleach molds from composites, some composite manufacturers have then decided to recommend that owners rachet up the sodium hypochlorite concentration, by ignoring dilution recommendations on sodium hypochlorite-based products for specific materials commonly used in the construction of decks, on these products label directions. They do this even though OSHA states “When you use biocides as a disinfectant or a pesticide, or as a fungicide, you should use appropriate PPE, including respirators. Always, read and follow product label precautions. It is a violation of Federal (EPA) law to use a biocide in any manner inconsistent with its label direction.”! These “biocide” based products are generally 5%+ sodium hypochlorite, further exacerbating fungus problems, by making the molds more resistant to the chlorine bleaching effect, while further bleaching the color of the composites! When these products generally ultimately fail in bleaching the funguses and/or result in rapidly returning funguses, they then generally recommend specialty products, only available over the internet, with even greater sodium hypochlorite concentrations & more volatile surfactants, one of which has a “short shelf life”!

Trex® where the “MUST be used within 30 days” product was recommended to be routinely used “Spring and Fall” until it became mold colonized with common black & green molds. The owner that sent us this picture was routinely spending a fortune laboriously using this product, watching these funguses come back sooner & sooner while getting worse & worse with each application. Perhaps you are experiencing this with a chlorine-based sodium hypochlorite product?

Semiannual routine use of any sodium hypochlorite based product, at any sodium hypochlorite strength, generally results in visible fungus stains never really going away, especially when composites are wet, with water, as water generally magnifies stains in composites. If the fungus can still be seen, it will likely rapidly return when composites receive moisture. Even if the molds can no longer be seen, the molds will likely rapidly return if sodium hypochlorite has been used because, as OSHA states; “In most cases, it is not possible or desirable to sterilize an area, as a background level of mold spores comparable to the level in outside air will persist”. “Outside air” is where most composites are located. Over time, the routine use of sodium hypochlorite generally results in the complete mold colonization of composites. This generally results in the molds no longer spotting but turning the entire composite boards black and/or green, with molds. When left unbleached, then the green molds generally rapidly grow, but sometimes they grow first!

CORTE-CLEAN_CORRECT-DECK_BEFORE_MOLD-LICHEN-MOSSCorrect Deck® heavily colonized with black & green molds, previously only routinely cleaned with sodium hypochlorite, installed with stainless steel deck screws, which do a good job of hiding underlying corrosion issues due to this metal generally turning a dulling blackish/grey color & unseen pitting as the corrosive cleaning chemical works its way down the screws!

Composite owners who use corrosive to metal sodium hypochlorite-based cleaning chemicals generally notice red or black rust corrosion stains around metal deck screws & nails “IN” composites. These stains act like a WARNING LIGHT going off! Most choose to ignore???!!!

Trex® where “sodium hypochlorite” was recommended to be routinely used used, “Spring and Fall”, in their “Mold Technical Bulletin” until completely mold infested! Notice the black spots growing into mold colonies & the red rust corrosion bleeding from the screws into the composites. What do you think this corrosive to structural metal cleaning chemical has done to the non-visible joist hangers, nails or screws under the decking?

There’s good reason the structural metal decking hardware manufacturers have disclosed the “corrosion risks” of “cleaning chemicals” such as those that contain “sodium hypochlorite” or “oxalic acid”! See your specific decking hardware manufacturer literature or call the manufacturers & ask “is it OK to use corrosive cleaning chemicals, such as sodium hypochlorite or oxalic acid, that will come into contact with structural metal?”! There is likely good scientific reason related to corrosion to why one of the most well-known sodium hypochlorite based cleaning products, “CLOROX® OUTDOOR BLEACH CLEANER”, has disclosed “DO NOT USE THIS PRODUCT IN FULL STRENGTH”, “Always dilute strictly in accordance with label directions” for “galvanized” “materials”, “Strength” “Low (Green)” “Dilution” “1:21” “6oz (3/4 cups) of product to 122oz (15 ¼ cups)” of water, as this product is believed to be 6.15% sodium hypochlorite! Most retailers, composite & chemical manufacturers have recommended & sold sodium hypochlorite based products at greater than 5% sodium hypochlorite concentrations, which label directions recommend they be “applied at full strength”! These products still aren’t even close to the “20%” sodium hypochlorite strength which OSU has proven to be scientifically ineffective in mold remediation with wood, but will likely rapidly corrode structural metal decking hardware, especially when used at strengths above what CLOROX® recommends!

Corroded Joist hanger & nails!

“Galvanized” “materials” are almost always used in the manufacturer of joist hangers & nails, to structurally support & hold together almost all composite decks, due to these items being generally recommended by composite deck manufacturers in “Installation Guides”, often in the same brochure as the “Composite Deck Care & Cleaning” literature. The rare exception is where more expensive stainless-steel joist hangers & fasteners have been used. Stainless-steel is commonly used to fasten composites to the structure under it, with screws, especially when hidden fastener systems are used. While stainless steel is generally more resistant to corrosive cleaning products than galvanized metal, it is not immune to corrosion, as it generally “pits”, resulting in the loss of structural value.

Corroded “pitted” stainless steel screw commonly used to attach composites to the structure underneath.

So, what have the retailers, composite & chemical manufacturers commonly recommend in an attempt to hide the corrosion the sodium hypochlorite recommended products caused?

Does “oxalic acid” based products, known as “deck brighteners”, commonly recommend to “remove rust and/or tannin stains” ring a bell? Composite manufacturers have chosen to recommend this generally corrosive to metal cleaning chemical even though at least one chemical manufacturer of this acid-based product states on its label directions “DO NOT USE ON” “METALS”, but claim their product is for “decking”, where structural metal decking hardware is almost always used. Why any chemical manufacturer would produce corrosive to metal deck cleaners or composite manufacturer would recommend corrosive to metal deck cleaners, or retailers would sell corrosive to metal deck cleaners makes no sense, especially since this chemical is not compatible with sodium hypochlorite. This is why this specific products label directions state “Do not mix with any other products, especially those containing chlorine or bleach.”!  The recommendation & use of these two non-compatible corrosives to metal cleaning chemicals to clean porous materials is dangerously reckless & unconscionable by any person or company.

Corroded screws & nails commonly used by contractors & those cutting corners to foolishly save money on construction costs, then choose multiple perceived inexpensive corrosive cleaning chemicals to routinely clean their expensive otherwise longer lasting composite deck!

Rapidly returning pesky mold stains are generally only an unhealthy unsightly nuisance that costs more time & money to initially properly thoroughly Corte*Clean®. Irreversible corrosion to structural metal, caused by the recommendation & those profiting from corrosive composite deck cleaning chemicals products, especially when recommended be used on a routine basis, generally leads to extremely laborious & expensive early replacement when corrosion is noticed. Do you think retailers, chemical & composite manufacturers are going to replace the irreversible corrosion damage they have caused by recommending and/or profiting from the sale & use of corrosive oxalic acid or sodium hypochlorite-based cleaning chemicals? You really should ask them before purchasing & using sodium hypochlorite or oxalic acid corrosive to metal cleaning products.

Corroded galvanized nails almost always used with joist hangers in deck construction!
Corroded decking joist hanger & nails!!!
Corroded structural metal I-Beams under composite decking as recommended & sold by at least one major composite manufacturer who routinely recommends sodium hypochlorite for cleaning molds!
WARNING! It is HIGHLY recommended that composite owners get their decks professionally inspected on a yearly routine basis, especially if they have noticed corrosion, sodium hypochlorite or other corrosive cleaning chemicals have been used, salts have been used to melt ice or it is located in a corrosive environment, such as near the ocean! Nothing could be more expensive than a deck collapse where people are injured or worse!

Failure to replace structural metal, when corrosion is noticed, can lead to structural failure, when generally under load from the increased weight of people! This is inexcusable, especially if people are injured or worse, especially when it could have been totally avoided by retailers, composite & chemical manufacturers.  This is currently the #1 Ticking Time Bomb in the decking industry, most retailers, chemical & composite manufacturers & owners continue to ignore!

Could the routine recommendation & use of sodium hypochlorite to clean mold from composite decking, corroded the bolts & joist hangers, like the above photo & lead to structural failure, that held the below ChoiceDek® to the header attaching it to the house? Why would any person or company ever even take the risk, when people could be injured or worse? Nothing could be more expensive!
We are seeing & hearing about more deck collapses with composites as the years go by. Faulty construction practices are likely sometimes to blame? Do you think the routine recommendation & use of corrosive to structural metal cleaning chemicals makes decks more or less likely to structurally fail? Ask yourself that question before ever using a corrosive to metal deck cleaning product!

Composite manufacturers generally start out by recommending a “soap” which can break down stains, exacerbate cleaning problems. They generally recommend a specific liquid dishwashing detergent which state on its label directions “DO NOT MIX WITH BLEACH!” because dishwashing detergents generally contain ammonia!  There is a potentially deadly serious reason why OSHA states “Never mix chlorine bleach solution with other cleaning solutions or detergents that contain ammonia because this may produce highly toxic vapors and create a hazard to workers.” When this generally almost always fails in cleaning composites, composite manufacturers commonly recommend a “sodium hypochlorite” based product, to clean “mold & mildew”. They then recommend an “oxalic acid” based product for cleaning “rust”, when composite owners complain about the rust stains the sodium hypochlorite has caused. Composite manufacturers then generally recommend specific products for cleaning “grease & oil” when the first three fail.  Composite manufacturers then generally recommend a specific brand of “oil stain remover” which states on its label directions “do not mix with other chemicals”, but is designed to be left on the decking till it dries out.

WARNING! Using multiple non-compatible cleaning chemicals, one after the other, to clean specific stains, from porous composites, which can soak into composites, can release poisonous toxic fumes!  DO NOT DO MIX CLEANING CHEMICALS!! POISONOUS TOXIC FUMES WILL VERY LIKELY RESULT FROM POROUS COMPOSITES. Read & follow any chemical cleaning products label directions, especially WARNINGS & DISCLOSURES!

Do you think using non-compatible chemicals, one after the other, to clean porous (soaks into) composites could release toxic poisonous gas? Commonly recommended ammonia based liquid dishwashing soaps, sodium hypochlorite, oxalic acid, oil stain removers & most other chemical based products can & generally do release poisonous toxic fumes when used one after the another to clean porous composites. Any person, especially composite manufacturer employees that have tested and/or used these chemicals in order to recommend them, would be recklessly foolish to not carefully read & follow these products label directions, or OSHA guidelines, especially when recommending specific chemicals and/or products to the uneducated general public, be used in conjunction with one another, for cleaning composites of specific stains!

ChoiceDek® Composite Post Cap – Before/black mold stains/cleaned w/only sodium hypochlorite & after Corte-Cleand®

Hopefully you haven’t experienced toxic, poisonous outgassing as we unfortunately have, when proving Corte*Clean® alongside multiple other cleaning products for major publicly traded composite manufacturer. The poison generally smells like burnt rubber, generally resulting in temporary loss of smell/taste & a terrible nauseating chemical headache, that can last for hours or days! Breathing this toxic gas by anything living can lead to long term debilitating health issues, especially with the young, the elderly, or those that suffer from breathing conditions; such as asthma, bronchitis or emphysema. All known retailers & composite manufacturers have all been made well aware these facts, since approximately 2006, but continue to ignore the risks they recommend to their customers & employees who follow specific cleaning chemical recommendations.

Trex® Before Black Mold Stained (left of picture) & After Corte-Clean® (right of picture).

When we bring up the science, outrageous costs, time, labor & risks or dangers of specifically the multiple cleaning chemicals composite manufacturers continue to recommend, some composite manufacturers have chosen to no longer recommend our proven product in retaliation. A former CEO of one of the largest publicly traded composite manufacturers told us “his mother had been using chlorine bleach for decades to kill mold, so he was recommending it to his customers” even though he was shown the scientific facts? The cleaning recommendations, specifically as it relates to remediating common molds from composites, based upon beliefs, not science, by all known composite manufacturers has been very similar to selling cigarettes, then denying they cause cancer, & all kinds of other problems, in the pursuit of profits over customer safety, while preying on the uneducated beliefs.

Corte-Clean® does NOT contain sodium hypochlorite, the active biocide in Chlorine Bleach; acids or phosphates!

What is shocking is the fact that unscrupulous chemical manufacturers & retailers continue to produce, market & sell products containing sodium hypochlorite, specifically for cleaning molds & other funguses from composite decks? They know all the facts, yet they continue to prey on the uneducated consumers beliefs. How any reputable person or company could recommend or profit from the “Chlorine Bleach Scam” is shameful & doing a disservice to this otherwise amazing industry.

When we called, they recommended a specific brand of liquid dishwashing detergent even though this products label directions states “DO NOT ADD BLEACH!” They then go on to recommend a “Brightener” that “contain oxalic acid” & state “Deck brighteners contain oxalic acid, which will remove tannins.” They then again recommend “soapy water” for “Oil/Grease/Food”. Then under the button “EARLY GENERATION PRODUCTS”, which likely means non-PVC caped recycled plastic & wood composites, they state under “Dirt and Debris” to “Clean deck to remove dirt and debris. Soap and water is all that is needed.” Under “Oil/Grease/Food” they then recommend an “OIL STAIN REMOVER” which states the “COVERAGE: Treats a stain 3 feet in diameter. Approximately 6 square feet” & states “do not mix with other chemicals.” (like “soap” & “oxalic acid”!) & costs “$13.99” + “Standard shipping $7.95” for a total of $21.94 from this products website. Then it is stated under “Mold and Mildew” that “Semi-annual (spring and fall) cleaning of your deck is important to prevent the build-up of pollen and other debris that can support the growth of mold. Refer to Mold Technical Bulletin for specific cleaning recommendations”. You then click the “Mold Technical Bulletin” PDF link that states “How to remove Mold from” this companies “Composite & PVC Decking”, which states, “If mold colonies appear, clean the deck with a commercial deck wash containing a detergent and sodium hypochlorite, commonly known as bleach. This chemical will remove the mold” & “If the deck has not been cleaned regularly, it may require several treatments with the deck wash to completely remove all mold colonies.” They then recommend two (2) specific sodium hypochlorite-based products, the first of which doesn’t appear to have been origionally designed to clean composites of common black mold, as this products label directions from its website states “Before” with a picture of a dirty weathered grey black mold stained wood deck, & “After” photo shows a cleaned wood deck. This product then describes itself as a “DECK CLEANER”, “FOR CLEANING PRIOR TO STAINING” which claims it “Removes dirt & mildew stains”, from “wood and other surfaces”, then states, “It cleans stains caused by mildew, dirt, algae and mold”, & that this product “CLEANS UP TO 300 SQ. FT”. On the back of this products label directions, it states “Use on decks, wood siding, shakes, shingles, and fences. Also recommended for use on concrete, brick, stucco, tile, and vinyl. Use of this product may return the original green color to pressure treated wood. Application of this product may cause a fuzzy appearance to wood previously damaged by pressure washing or excessive weathering. Application to new wood or newly sealed wood may cause spotting and discoloration. May cause redwood to darken”. Vinyl is PVC plastic, not the PE recycled plastic known for mold problems with this composite manufacturers non-capped products. Then this product states “PRECAUTIONS: Do not mix with any other chemicals as hazardous fumes may result”. Such as the “soap”, “oxalic acid” or “oil stain remover”! This product then recommends being “applied at full strength” while containing “sodium hypochlorite” at “% ≥5.0 – ≤10” according to this products Safety Data Sheet. Newer packaging states “removes dirt, mold & mildew stains” with a sticker and/or new label addition that now states “ALSO FOR CONCRETE & COMPOSITE”. This product generally retails from a home improvement warehouse for $9.98 + tax per 128 oz. or 1 gallon. The 2nd recommended “Mold and Mildew” product this composite manufacturer recommends is only available over the internet through the chemical manufacturer website. The “Description” on this products website then states “Composite Deck Cleaner & Enhancer is a heavy duty, mildly alkaline chlorinated mold and mildew remover/cleaner designed specifically for composite deck cleaning.” They claim their products “chemicals take care of your most stubborn mold, mildew and soil build up” while it “MUST be used within 30 days”. It then states “Each bottle should cover the entire process for 100 square feet of decking” & “Do not mix the deck cleaner chemicals with any other chemical as hazardous fumes may result”, like the recommended “soap”, “oxalic acid” or “oil stain remover”! This product then states “DO NOT DILUTE WITH WATER”. This product costs $19.98 + shipping! The average 300 Sq. Ft. composite deck will need 3 gallons or $59.94 + $40.37 (shipping to our zip code 94925, shipping may be less or more for you?) for a grand total of $100.31! The 3rd product this company recommends in their “Mold Technical Bulletin” claims on its website that it is “oxalic acid based liquid cleaner, brightener and stain remover”, “works best on natural wood or hard to clean surfaces such as concrete.”, “CLEANS & BRIGHTENS weathered gray wood surfaces”, “REMOVES STAINS associated with MOLD & MILDEW from wood and masonry” & “REMOVES TANNIN STAINS from bleeding woods such as cedar”. This products label directions state that it is a “BRIGHTENER STAIN REMOVER” for “WOOD · COMPOSITE DECKING · MASONARY” for cleaning “DIRT · MOLD · MILDEW RUST & TANNIN SURFACE STAINS”. This product claims it “MAKES UP TO 8 GALLONS”. You then click on the PDF “Spec Sheet” button & it states “removes dirt and stains caused by mildew and tannins”, then states, that this product “cleans and brightens weather-beaten wood” & that it is “Safe for use on” this specific composite manufacturers composite decking products, “and other plastic/wood composite surfaces” while claiming “1 gallon concentrate (makes up to 5 gallons)” [thought it made “8”?] and that the “COVERAGE” is “Up to 2,500 sq. ft. per gallon with a five to one water dilution”.  The label directions then state “if spraying, use NIOSH approved respirator”. Under “SUGGESTED APPLICATIONS” this product states “Remove mildew and clear finishes to restore wood to its original look”, “Neutralize and brighten surfaces that have been stripped with corrosive strippers”, then, that it will “Remove tannin stains from bleeding wood, such as cedar and redwood”, & “Ideal for cleaning and brightening most exterior surfaces, especially outdoor wood furniture, fences, decks and docks, including” this specific composite manufacturers products “and all other plastic/wood composite decking materials”, “DO NOT USE ON” “METALS”, & “Do not mix with any other products, especially those containing chlorine or bleach.”, Like the “soap”, “oil stain remover” or two “sodium hypochlorite” based products! This product costs $24.98 + $4.99 shipping for a total of $29.97. In summary, you’ll likely spend approximately $3 on “soap”, then $21.94 on the “OIL STAIN REMOVER”, then another $9.98 on 1st sodium hypochlorite product for the first “Mold” cleaning,  another $9.98 for the second “Semi-annual (spring and fall)” routine “Mold” cleaning, & $29.97 for the “brightener” that contains “oxalic acid” for a conservative total first year estimated cost of $74.87, on this composite manufacturer’s recommended cleaning products! You’ll likely then quickly discover why the 2nd “Mold and Mildew” product is recommended, when the 1st product originally designed to clean “wood” of “mildew” no longer bleaches out the common black molds? Then, with routine “Spring and Fall” use, the black molds never really go away, especially when the deck is wet, with water, as water generally magnifies mold stains on this composite manufacturers products. When this generally occurs, this composite manufacturer then commonly recommends the purchase & use of the 2nd, more expensive, “Mold and Mildew” product, for your “Semi-annual (spring and fall)” routine cleaning. Generally, owners of this composite manufacturers products then begin to notice the black mold spots never really being bleached out, especially when the composite is wet, with water, but colonizing the composites with black or green molds. These molds & other funguses then generally begin to rapidly returning more often, resulting in the need to purchase & using this expensive product more often than “Semi-annual (spring and fall)”?  This 2nd “Mold and Mildew” recommended product will cost $100.31, from their website to clean the average 300 Sq. Ft. deck. Plus, you’ll generally need to pay another $21.94 for the “OIL STAIN REMOVER” to remove the oil stains from generally the barbecue, for a 2nd current yearly total cost of $122.25, but fortunately you may have some left over “oxalic acid” based product? By year 10 you will likely have conservatively spent $1,175.12+ following this composite manufacturer cleaning chemical recommendations. Now factor in the time, labor & other risks of using multiple, generally, non-compatible, corrosive to metal cleaning chemicals, which can result in premature expensive early replacement or potential structural failure! Please do your own dudiligance, as it would likely only cost you $39.99 for a single 2000A bag of Corte*Clean®, to initially clean this 300 Sq. Ft. composite deck, when stains were first noticed! Then to maintains this same deck’s clean appearance, on a “Semi-annual (spring and fall) cleaning of your deck is important to prevent the build-up of pollen and other debris that can support the growth of mold.”, owners of this manufacturers composites should be using up to ½ the Corte*Clean®, when using it at the “routine cleaning” strength, or spending up to ½ the money, thereafter. Many of this composite manufacturer composite deck owners use less & less Corte*Clean®, diluting it further, for the proactive cleanings & notice their composites generally staying clean for longer & longer, while spending less & less money! After 10 years, to keep this average 300 Sq. Ft. of this composite manufacturers composite decking clean, with Corte*Clean®, it currently costs $399.90 +/-, but should ultimately cost less & less as you fine tune how little product you can proactively use to keep to keep this composite manufacturer products clean, which makes it even more environmentally responsible. $1,175.12 – $399.90 =

A conservative approximate savings of $775.22 over 10 years for cleaning every 300 Sq. Ft.!

After reading this manufacturers “Composite Deck Care & Cleaning Guide” & “Code of Conduct & Ethics” do you think their employees, starting from the top down, are adhering to their own policies when testing, recommending and/or using the recommended cleaning chemicals?

 

Composite manufacturer brand #2 cleaning chemical recommendations as of 8.20.2018…

This composite manufacturer states under “Care & Cleaning” that this companies composites have “Simple, Easy Cleaning & Maintenance Instructions”? Their website then states ” Our new embossed texture not only looks like natural wood grain, but it is also easy to clean. Our decks do not require painting, sealing or staining. So, don’t be afraid of messy barbecues. Ketchup and mustard spills just wipe away. Simply perform periodic cleaning with soap, hot water and a soft bristle brush. The best time to clean is after installation and semi-annually (spring and fall) to remove any debris”. They recommend three (3) “suggested cleaners for periodic maintenance”. You click on the link for the first product, which brings you to this products home page, where you see a button that says “Select your surface” and has pictures of brick/wood & what appears to be a roof & stucco siding and a button that states “Learn More”. You click on it and it brings you to a “PRODUCT PICKER” page. You scroll down & see every possible building material but a plastic composite deck? So you click on the button with what appears to be an artist rendering of wood boards & states “DECKS”, as this seems logical? You click on the first product that states “32 oz. House and Deck Concentrate with Hose End Sprayer – treats approx. 600 Sq. Ft.” The products label directions states “REMOVES AND PREVENTS STAINS CAUSED BY MOLD, MILDEW, MOSS, ALGAE & LICHEN”, then states, “Do not mix {this product} with detergents or other chemicals” & “treats from 400 Sq. Ft. to 600 Ft.” & has a picture of wood & states “DECKS/FENCES” but states nothing about plastic composite decking & costs $27.95. You hit the back button, click the button for the larger container, which claims this product “coverage 600- 1000 SQ. FT.”, as this product appears to be more of a value, as it states “Economical – makes up to 5 gallons” so you click the “BUY NOW” button. The product costs “$29.95” + “Flat Rate Shipping” of “$9.00” for a total of “$38.95”. You order it, it shows up, you follow its label directions & presto, generally nothing, because under the “Results, Time & Application” button on this products website, from which you bought the product, it states “BLACK STAINS: Removed in 1-6 weeks from non-roof surfaces” & states “Do not mix {this product} with detergents or other chemicals”! Unfortunately, after weeks, it still looks like it has the measles from black molds, or green, from green molds, & likely rained, rinsing this product, preventing it from working? You click on the next button on this composite manufacturers website, which recommends a 2nd product, which takes you to a specific stores website. The product is an “OIL STAIN REMOVER”, not for the molds on your composites, which claims the “COVERAGE: Treats a stain 3 feet in diameter. Approximately 6 square feet” & states “do not mix with other chemicals.”, such as the first product which doesn’t recommend you rinse it? This 2nd product costs $14.98 + tax from this specific stores website, which stated this product was “Unavailable for Pickup” from our local store. You search for the product online, find its website & buy the product, because, under the barbecue has plenty of oil stains that the first product wasn’t designed to clean. The product costs “$13.99” + “Standard shipping $7.95” for a total of $21.94. The product arrives, you worry about ignoring the 1st products disclosure related to mixing chemicals, you then, thoroughly rinse the first product to make sure you don’t accidently mix these chemicals in this porous material, guaranteeing the first won’t work, in case the rain hadn’t already & apply the 2nd product by following its label directions. The product removes the oil stains. The only problem is you now need to buy enough to finish the rest of your 300 Sq. Ft. composite deck! 300 Sq. Ft – 6 Sq. Ft results in you needing enough product for the rest of the 294 Sq. Ft., or 294 divided by 6 or for another 49 purchases of this product at $21.94 each, for a total cost of $1075.06! Quickly, you decide that is too much money. You click the next “Premium Deck Cleaner” button on this composite manufacturers website, for the 3rd recommended product, which again takes you to a specific retailers website, which again states “This item is no longer available {at this retailer}.com.”, but has a artist rendering pictures of what appears dirty weathered grey black mold stained wood deck, which states “Before” & “After” photo shows a cleaned “wood” deck. This product then describes itself as a “DECK CLEANER”, “FOR CLEANING PRIOR TO STAINING” which claims it “Removes dirt & mildew stains” from “wood and other surfaces”, then states, “It cleans stains caused by mildew, dirt, algae and mold” & that this product “CLEANS UP TO 300 SQ. FT”. On the back of this products label directions, it states “Use on decks, wood siding, shakes, shingles, and fences. Also recommended for use on concrete, brick, stucco, tile, and vinyl. Use of this product may return the original green color to pressure treated wood. Application of this product may cause a fuzzy appearance to wood previously damaged by pressure washing or excessive weathering. Application to new wood or newly sealed wood may cause spotting and discoloration. May cause redwood to darken”. Then this product states “PRECAUTIONS: Do not mix with any other chemicals as hazardous fumes may result”, such as the “soap”, the 1st product or the “oil stain remover”! This products label directions recommend it be “applied at full strength” while containing “sodium hypochlorite” at “% ≥5.0 – ≤10” according to this products Safety Data Sheet. Newer packaging states “removes dirt, mold & mildew stains” with a sticker and/or new label addition that now states “ALSO FOR CONCRETE & COMPOSITE”. This product generally retails from a home improvement warehouse for $9.98 + tax per 128 oz. or 1 gallon. Then this composite manufacturer recommends, under “Oil and Grease Stains (including lotions and candle wax)” “Household degreasing agents, such as {a specific brand of} dishwashing detergent, should be used to remove the oil and grease stain as soon as the stain is noticed.” This product generally retails for approximately $3 but clearly states “DO NOT ADD BLEACH!”, such as the previous “bleach” based recommended product. Then this composite manufacturer recommends under “Below are suggested recommendations for specific cleaning issues:”, for “Water Spots”, to “use a deck brightener containing oxalic acid”. We called this composite manufacturer & they recommended a specific product, as this product is manufactured by the same company that manufacturers the other sodium hypochlorite-bleach based “Premium Deck Cleaner” product. This product claims to be a “GENTLE CLEANER FOR: PREVIOUSLY STAINSED WOOD + BARE CEDAR & REDWOOD” to be used as a “DECK BRIGHTENER & WASH”, then states “CLEANS, BRIGHTENS & REMOVES MOLD & MILDEW STAINS”, “Excellent for rust & tannin stains” & “GENERALLY WASHES AWAY DIRT FROM PREVIOUSLY STAINED SURFACES”. This products Safety Data Sheet states it contains “Ethanedioic acid, hydrate”, commonly known as oxalic acid! Under “Incompatible materials” on this products label directions, this product states “oxidizing agents”, such as the “sodium hypochlorite”, as sold in the other recommended “Premium Deck Cleaner”, “wood” product for “mildew”! This is a sneaky way of disclosing not to mix these two non-compatible cleaning chemical products. This product retails from a box store for $9.98 + tax per 128 oz. or 1 gallon. Then under “Mold”, this composite manufacturer states “Based on our testing the most effective cleaner for quickly removing mold stains is” the sodium hypochlorite-based product. Then they state “a bleach-based cleaner may temporarily lighten the surface appearance”. Then they go on to state “After cleaning, for long lasting results”, use the first recommended above product (above) “as an inhibitor”. They then go on to state the first product “can also be used as a cleaner in situations where instant results are not needed” & “Please refer to Mold and Mildew Cleaning for more information on mold removal.” You click on the link & a PDF opens for “MOLD & MILDEW” for “SUGGESTED CLEANERS” which have links to the 1st & 3rd products. For the 3rd product it then states “Contains bleach for Instant Results*” & “*Most cleaners contain Sodium Hypochlorite (commonly known as bleach). Any cleaner containing bleach may lighten surface wood fibers of the product while removing mold stains.” Back to the composite manufacturer “suggested recommendations” under “Rust stains / stubborn spots” they state “A cleaner containing oxalic acid, commonly known as deck brighteners, can be used to remove these stains.” Then this composite manufacturer states “For additional cleaning solutions, please visit the links below.” The “Tannin Instructions” PDF link then states; for “TANNIN, WATER OR RUST STAINS” & discloses “Lower-quality steel fasteners or electroplated screws are not recommended as they may not last as long as the deck boards and they can also create temporary stains your deck. On newly installed decks, runoff from metal objects, such as lawn furniture or decorative iron railings can create some temporary staining as well. These rust stains can also be easily removed with the use of a deck cleaner containing phosphoric or oxalic acid (ingredients will be listed on the front label or on the label on the back of the container).**Follow all package directions for proper usage, safety precautions and disposal. In some cases, more stubborn stains will require reapplying cleaners until the desired level of cleanliness is achieved. At times, brushing the deck with a hard bristle brush may be necessary to remove any stubborn staining. Excessive scrubbing may cause a temporary scuff mark that will weather away. Always test chosen cleaners in a small inconspicuous area of your deck for approved results. Never mix any other cleaners (ammonia, phosphoric acid, etc.) with bleach.” This composite manufacturer wants you to buy & use the first product for $38.95, the 2nd product for $21.94, the 3rd product for $9.98 + tax, the 4th product for call it $3 + tax, & the 5th product for $9.98 + Tax. Without tax, that’s $83.85 & assuming these products all clean 300 Sq. Ft., which they don’t. This total yearly price does not contain the “phosphoric acid” they recommend? You’ll have to purchase & laboriously use most these products as this manufacturer suggests at least twice per year “semi-annually (spring and fall)” to keep this decking clean so that would cost $38.95+$9.98 +$21.94 + $3+ $9.98 for a total initial purchase price cost of $167.70! You likely only need to purchase the $38.95 product once yearly, due to the coverage this product claims to clean & keep clean, so we deducted it from the 2nd yearly “Spring & Fall” recommended cleaning chemicals cost of this composite manufacturer or $167.70 – 38.95 equals a total yearly cost of $128.75 + TAX to purchase all these composite manufacturer recommended cleaning chemicals! If you follow this composite manufacturers cleaning chemical recommendations for 10 years, that equals $1,287.50 + TAX! Now factor in the time, labor & other risks & replacement costs! Please do your own dudiligance, as it would likely only cost you $39.99 in for Corte*Clean® to initially clean this 300 Sq. Ft. of this companies composite decking, when stains were first noticed, of all common stains! Then to maintains this same composite deck’s clean appearance, owners of this manufacturers composites should be using approximately up to ½ the Corte*Clean®, when using it at the “routine cleaning” strength, or spending up to ½ the money. Many of this composite manufacturers composite product owners use less & less Corte-Clean®, diluting it further, for proactive routine cleanings & notice their composite deck staying clean for longer & longer, while generally spending less & less money without the risks of using multiple cleaning chemicals! After 10 years, to keep this average 300 Sq. Ft. composite deck clean, with Corte-Clean®, is currently approximately $399.90 +/-, but should ultimately cost less & less as you fine tune how little product you can proactively use to keep it clean, which makes it even more environmentally responsible. $1,287.50 – $399.90 =

A conservative approximate savings of currently $887.60 over 10 years for cleaning every 300 Sq. Ft.!

Please do your own dudiligance for your specific composite manufacturer cleaning chemical recommendations, as some are even more expensive, dangerous & outrageous!

Black & Green Mold stained Composite Deck (left) & Corte-Cleaned® (right).

1st add up the cost of all the cleaning chemicals composite manufacturers recommend to clean 300 square feet, the average composite deck size. Then factor in the time or labor costs to use them. Are the cleaning chemicals compatible for cleaning porous composites without toxic off gassing? Are they corrosive to the structural metal? If routinely used, will they keep your composites clean for longer & longer for less money or shorter & shorter while costing more money? What is the true cost, especially when factoring in the cost of replacing corroded structural metal or just letting it fail when under load from generally people? Can you really put a price on safety?

 

Why do you think composite manufacturers recommend multiple perceived inexpensive cleaning chemicals, which ultimately cost more money?

 

Could it be the routine financial kickbacks, for recommending multiple, perceived inexpensive, but ultimately more profitable cleaning chemicals, especially those that are sodium hypochlorite based & scientifically un-proven for black mold, generally resulting in its rapid return, & the need for composite owners to rapidly re-purchase/laboriously re-use, while irreversibly corroding out structural metal, generally requiring the early expensive replacement, before otherwise long lasting composite decking is fatigued, but is generally always replaced with the decking structure, leading to new composite decking being purchased sooner, & increased profits, outweighs customer safety & overall satisfaction with the composite decking industry & reputation? We’d almost think its funny what composite manufacturers routinely recommend for cleaning, if it wasn’t so expensive & potentially dangerous! Any person who can read any products label directions and/or has a basic middle school chemistry education should & would know better than to recommend multiple non-compatible chemicals be used in conjunction! From the looks of it, especially with what it has already cost composite manufacturers & owners, you’d think they let untrained uneducated individuals recommend cleaning chemicals, especially when it comes to molds, which has plagued the composite industry, as it doesn’t take a genius to do the basic research to understand what should never be used, especially to clean longer lasting porous composite decking with structural metal!

Corte*Clean® working removing Mold Stains & Tannins from Trex®.

Corte-Clean® is a single proven product, to clean composites, of all common stains, not just those caused by molds, in a far safer, more cost effective & environmentally responsible, biodegradable manner. More importantly, Corte-Clean® is proven in generally keeping composites clean, at generally at a much lower cost, for longer & longer periods of time when properly proactively used. Corte-Clean® has existed for over a decade because of this fact. Please do your own dudiligance by reading our customers verified testimonials or reviews on Reviews.IO!

Corte-Clean® BEFORE & AFTER artist rendering

Corte, LLC provides a GUARANTEE & LIMITED WARRANTY along with quality customer service, by people whom have actually cleaned numerous composites with Corte*Clean®, & just about everything else before discovering Corte*Clean®, for major composite distributors & manufacturers! Corte*Clean® was originally developed by a chemical manufacturer owner, who’s business was established in 1960 & a chemical engineer professor for a major university. They specialized in automated car wash cleaners & cleaners in the food industry, specifically with wine production equipment & mold remediation. Corte*Clean® was developed to clean his personal Trex® deck & dock, in the San Francisco Bay Area, then tested by composite distributors & manufacturers until perfected. Corte LLC was founded in 2006 to bring the proven product to market. Corte LLC wants every customer to be satisfied with the results of Corte*Clean®, so they can spend more time enjoying their clean composites, & less time & money cleaning them & keeping them clean. If you are one of our many new customers, that has neglected, improperly previously cleaned, only power washed or used sodium hypochlorite in an attempt to clean molds, until it generally no longer bleaches the mold stains out and/or the molds rapidly return, it is likely going to take you additional time & money or Corte*Clean® to initially Corte*Clean® infested composites. You may not have that instant “WOW” cleaning effect, almost all Corte*Clean® experience. Your neglect to properly proactively Corte*Clean® may have caused weathering issues, caused by stains or items blocking the sun from evenly bleaching/fading/weathering your decking, which only the sun can even out over time. Once thoroughly Corte*Cleaned® it is best to initially apply Corte*Clean® more often than Spring & Fall. We would recommend before composites receive moisture, to ensure composites are clean & keep composites clean. This will clean deeply infested stains that may not be visable or thoroughly removed throughout the composite boards, or before new spores, that have landed on the composites,  hatch, colonize & root into or other stains saturate. If you notice stains coming back, after composites receive moisture, you will know you didn’t thoroughly Corte-Clean® composites or proactively Corte*Clean® them often enough. Get ahead of the problem! Try to figure out how little Corte-Clean® you can use to keep composites clean.  The goal is to make sure you are ultimately spending less & less time & money keeping your composites clean for generally longer & longer periods of time, but if one cuts corners, this person is likely wasting time & money resulting in the rapid return of stains. DO NOT SKIP THE FINAL CORTE-CLEAN® LABEL DIRECTION WHICH STATES “When Corte Clean no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces. Corte Clean is designed to continue to clean any time it receives moisture. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse prior to using.” The best way to thoroughly rinse is to proactively apply Corte-Clean®, at the “routine cleaning” Corte-Clean® strength, before composites receive natural moisture from rain or snow. This final step will ensure composites remain clean, while removing deeply rooted or saturated stubborn stains over time. Always make sure composites are thoroughly rinsed, prior to using. If you are not willing to recognize the severity of the problem & properly use Corte*Clean®, by following its label directions, you will likely be a dissatisfied customer. PLEASE DO NOT PURCHASE Corte-Clean® if you are not willing to carefully follow its label directions. You will likely be wasting your time & money & be one of the bozos that states “It doesn’t work?”! You are likely dealing with a very serious problem, which we want to help you clean & generally spend less time & money keeping clean in the future! Corte*Clean® is proven to do this. NOTE: Corte-Clean® does have a “Best If Used By:” date on every 2000A bag, which is one (1) year from when it is manufactured. The fresher it is, the better & faster it generally works, especially when first used to clean neglected or improperly previously cleaned composites, so we recommend buying it directly from its website or a reputable retailer. Please DO NOT purchase more than you will be using in one (1) year from the Corte-Clean website. It will very likely fail you. Corte LLC does NOT Guarantee or Warrant Corte-Clean® after the “Best If Used By:” date on every bag. Corte-Clean® IS a cleaning chemical specialty product, which has a Safety Data Sheet (SDS) & will be shipped with Precautionary & Hazard Statements. READ & FOLLOW THEM. Corte LLC does NOT accept returns of Corte-Clean®. Make sure you want it, before you buy it. You can always buy more, if or when you need it. If you have reviewed the Corte-Clean® websites & have  any questions before one purchases/uses or after Corte*Cleaning®, especially if the desired results are not reached, before posting a negative review, please have the common decency to take digital pictures & to Contact US so we can help you!
