Please READ if you wish to educate yourself regarding common mold problems, the expense + numerous issues with most cleaning products & why Corte-Clean®?

 

Please review the entire Corte-Clean® website, Instructional Demo Video, & the Corte-Clean® Label Directions, to educate yourself regarding cleaning expensive composites, & keeping them clean. Not only does our small, one product, highly specialized family-run American Made grassroots business want to make sure you get composites thoroughly Corte-Cleaned®, while providing quality customer service by representatives that have actually cleaned numerous composites, we want to make sure you thoroughly clean the underlying issues from which most composites are made that can feed fungi, in order for composites to generally stay clean for longer & for future cleanings to generally cost less time, labor & money. Please read the well over 400 “Company Reviews” + over 200+ “Product Reviews” for a total of over 600+ customer verified testimonials on Reviews.IO.

 

 

Composites were generally sold to be “NO MAINTENANCE” by retailers, distributors, architects & builders, but commonly experience difficult to clean & keep clean tannin, grease, oil, rust & mold stains. Most chose to ignore composite manufacturer product literature which generally disclosed these cleaning issues. Corte-Clean® was designed specifically to only clean wood & plastic composites of all common staining issues, with an emphasis on those caused by fungi, such as common black & green molds. Corte-Clean® has been proven for well over a decade by composite manufacturers, distributors, retailers, installers, maintenance professionals & most importantly; owners.

 

 

Cleaning wood & plastic porous composites & keeping them that way requires cleaning chemicals designed for this specific purpose. You wouldn’t use chlorine bleach, intended to clean laundry, to clean a vehicle, unless one wished to cause expensive damage, especially on a routine basis. The same is generally true when using cleaning products designed to clean specific materials of specific stains that are not stated on cleaning product(s) label directions.

 

 

Generally black & green appearing mold (sometimes spelled mould) is common growing into composites, while mildew, a very specific mold subspecies, is not. Mildew generally appears white in color. When mildew is generally first noticed on wood, it generally looks silky white, which is common on wet freshly cut improperly stored solid lumber, until it dries out, then it generally looks powdery white. Perhaps you have seen mildew at a lumber yard? Mildew, including powdery mildew, is NOT generally the deeply rooted, difficult to clean & keep clean, rapidly returning, common pesky mold species, such as cladosporium or stachybotrys cartarum, commonly seen growing on/into building materials like composite decking & fencing. Like mildew, algae, which generally only grow in water, such as a improperly maintained or neglected swimming pool, isn’t common growing into composites unless they are generally submerged.

 

 

Mold stains occur after mold spores, generally in the air, land on composite & other building materials, receive moisture, germinate, grow hypha into a mycelium & become visible when it forms into a colony. Here is a map of generally where outdoor fungi are most likely to currently grow in the Continental Lower 48 United States {blue is not likely, green is low, yellow is moderate, orange is high & red is very high} [CLICK HERE]. The most common mold stains with composites generally start out looking like black oil drips, from a leaky motor on a driveway, when first noticed, & appear about the size of a dime or nickel. Composite owners often have no idea what it is? However, sometimes, green molds, which the uneducated believe is algae, grow first.

 

 

Chemical & composite manufacturers, along with retailers, have done a tremendous job of misleading composite owners into believing all molds are mildew, & green molds, mosses or lichens are algae. They do this so they can recommend & sell products generally designed to clean only “mildew” species of mold, and/or “algae”. Composite owners then purchase & use these products believing they are the right product(s) to remediate; or routinely clean & keep composites clean.

 

Lowe’s® ChoiceDek® with thoroughly dry mold stains. It is best to use Corte-Clean® when composites & funguses are allowed to thoroughly dry. When fungi thoroughly dry out, they shrink as they are starved of water & naturally die off.

When black mold stains no longer look like a black oil drip on a driveway, but thoroughly dry, it generally costs less time & money to Corte-Clean®, especially when composites are warm, their pours are allowed to expand & open, between the temperatures of 65 F. & 85 F. in direct sunlight. The correct temperatures & sunlight  allow the Corte-Clean® to get deep into the pourous surfaces of most composites to remove the deep set or below the surface stains with greater ease.

 

Most of the well-known, biggest branded composites, which are notorious for mold problems, especially those that are rapidly re-occurring are generally made with recycled Polyethylene (PE) plastics. The plastic commonly came from bags, shrink wrap, milk jugs, food packaging, etc. Unfortunately, the recycled plastic was not generally thoroughly cleaned of organic foods/debris/materials. The dirty plastics can provided the food for fungi that consume rotting organic matter, when it receives moisture.

 

The most commonly recommended chemical, by most composite manufacturers, under “Care & Cleaning”, for “Mold & Mildew” is “Sodium Hypochlorite“. Products containing this biocide are commonly recommended by composite manufacturers to be used on a routine “Spring and Fall” basis. The most commonly recommended brand name deck cleaning product by the largest composite manufacturers was originally designed to clean only “mildew” from “wood”, such solid wood decking, as originally stated on this products label directions.

Many sodium hypochlorite-based products additionally claim to clean only “vinyl“, a specific type of Polyvinyl Chloride (PVC) plastic. One composite manufacturer recommended sodium hypochlorite-based cleaning product claims to clean only “non-porous” “vinyl” PVC plastic of “mildew”, then goes on to state “It is a violation of Federal law to use this product in a manner inconsistent with its labeling”, even though the composite this company manufactured was made of PE plastic & wood while being porous & mildew is generally not the fungi problem staining their composites.

These products should not be used to clean other types of plastic, such as PE or Polypropylene (PP) based composites of common black & green molds, which are not mildews, unless one wishes to ignore these products label directions.

 

Mold infested TimberTech® composite deck made from virgin PE plastic & recycled wood colonized with mold from years of the routine recommendation & use of a sodium hypochlorite-based product intended to clean non-porous solid vinyl PVC plastic without wood.

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 mycelium has likely rooted throughout the plastic & is feeding off the wood fiber tannins!

 

Could the use of any sodium hypochlorite-based product, to clean mold, including mildew, on a routine “Spring and Fall” basis, result in rapidly returning fungi based on science?

Could the use of sodium hypochlorite based products designed to clean only wood, and/or PVC “Vinyl” plastic, excessively bleach/fade/weather and/or damage PP or PE plastic polymers?

Can sodium hypochlorite & oxalic acid be corrosive to structural metal decking hardware?

Could it be dangerous to use multiple commonly recommended non-compatible cleaning chemicals to clean specific stains from composites?
