RECOMMENDED by the LARGEST Composite DECK, DOCK & FENCE Manufacturers!

WARNING! Corte-Clean® Does NOT contain SODIUM HYPOCHLORITE, commonly known as CHLORINE BLEACH, which is CORROSIVE to STRUCTURAL METAL DECKING HARDWARE & SCIENTIFICALLY UNPROVEN FOR MOLD, from the wood, of which most composites are approximately 50% made, the #1 issue facing unsuspecting deck owners. Don’t get caught up in “THE CHLORINE BLEACH SCAM”, choose Corte-Clean®, which has been proven for over a decade.

Why choose Corte*Clean® to clean an expensive composite?

CORTE*CLEAN® is the proven solution for cleaning and inexpensively routinely maintaining composites of all common staining issues including mold & mildew stains, black spots, grease, oil, barbecue, tannin, leaf, pine needle, chalk, berries, sunscreen, olive oil, citronella candle oil, peanut butter, red wine, pet food, hard water, grass, ground in dirt, clay, brick, flower pot, rust, grime, green slime and most other stains that saturate the porous surfaces of most composites.


Corte*Clean® is a powerful cleaner specifically designed to cost effectively deeply clean porous plastic & wood composites, of the toughest stains, that are deep set or below the surface, and exposed wood fibers of tannins from which most composites are approximately 50% made, to eliminate tannin bleeding and the food from which funguses feed.  Other cleaners, that contain oxalic acid, known as “wood brighteners” generally only brighten exposed wood fibers while those that contain sodium hypochlorite, generally only chlorine bleach out and or leave behind these stains while generally causing irreversible corrosion to structural metal decking hardware such as joist hangers, screws or nails commonly made from galvanized or stainless steel. Corte*Clean® then soaks into the pours of composites and exposed wood fibers and continuse to clean any time it receives moisture, until thoroughly rinsed. Proactively  cleaning composites, as most composite manufactures recommend, at least twice (2X) yearly, Spring & Fall, or when stains appear, as Corte*Clean® is designed & intended to be used, preferably before composites receive moisture and stains appear and/or saturate, at the diluted Corte*Clean® strength, will have you generally spending less time & money keeping composites clean, once thoroughly Corte*Cleaned®. Corte*Clean® is/has been the low cost proven product to thoroughly clean and keep expensive composites clean, with less time cost & labor for approximately a decade.


Corte*Clean® does not have all the additional costs, risks, and time related to laboriously using multiple other expensive cleaning chemicals for specific stains.  You won’t need to purchase and use one product for mold & mildew stains, a 2nd product for rust & tannin stains or tannin bleeding from exposed wood fibers, a 3rd product for grease & oil stains, a 4th product for sealing composites and a 5th product to remove the sealer when it begins to weather/flake/crack off, look ugly and needs to be laboriously removed. Corte*Clean® has been proven effective by customers like you. It has been tested & endorsed by leading composite manufacturers & retailers who realize its many benefits over the competition. The information on this web site should be carefully considered. It will help guide you to why Corte*Clean® is the best, lowest cost, eco responsible choice when used to clean & routinely maintain expensive, long lasting composites. If Corte*Clean® can’t get composites clean and routinely proactively help to maintain them, at an even lower cost, while saving time & money, it’s likely nothing will. SEE TESTIMONIALS & REVIEWS!

2017 Trex® Transcend® 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.

Cleaning composites & keeping them that way is somewhat different than maintaining wood decking, especially those that are treated to prevent rot and/or fungal decay, such as black mold (common on composites) & white or sometimes gray colored silky looking mildew stains (common on wood, but extremely rare on composites). Failure to review the websites, or at least read & follow the Corte*Clean® label directions, will likely result in you being dissatisfied with our proven product. Please, DO NOT PURCHASE Corte*Clean® if you are not willing to thoroughly review the provided information and contact us if you have any questions.
