PLEASE READ BEFORE POSTING A NEGATIVE REVIEW!!!

Please immediately contact Corte LLC if you are not satisfied with our proven product, which has existed for over a decade, with so many positive reviews & re-peat customers. We are a small, 1 product, family run, American made business. We will do our best to help you, as we are EXPERTS in composites & keeping them clean.

We will call you back ASAP!

We want to make sure you not only get your composites THOROUGHLY CLEAN, we want to make sure you understand how to generally SPEND LESS TIME & MONEY, in the future, keeping composites clean. Corte-Clean® is proven to do this when used "at least twice yearly, spring & fall, or when stains appear" at the "routine cleaning" reduced "up to" 1/2 strength. If mold stains are returning, you are waiting too long to proactively Corte-Clean®, and likely wasting more time, labor and money than necessary! See how little Corte-Clean® can be proactively used to save. THis has the added benefit of being more ECO Responsible!

Corte-Clean® is the most recommended solution for deep cleaning Composite Deck, Dock & Fence of all common stains, NOT JUST those caused by MOLDS. Say goodbye to mold & mildew stains, black spots, grease, oil, rust and more with out the need to expensively purchase and laboriously use multiple non-compatible poisonous and/or corrosive to structural metal cleaning chemicals, especially those that contain oxalic acid or sodium hypochlorite, the active biocide in chlorine bleach which OSHA DOES NOT RECOMMEND FOR MOLD & science by Oregon State University has proven to be ineffective from the wood of which most composites are partially made. Don't be another sucker for "The Chlorine Bleach SCAM"!!!

“I've had Trex for about 15 years. Corte Clean is the only thing I have ever used. It works pretty darn good. It has been so rainy in Wisconsin this year, I just ordered more to clean it.”

“I bought a composite deck 6 or 7 years ago, to replace a wood deck, thinking I never had to do anything to maintain it. I think it is TimberTech, as I have friends that work for the Trex Company here in Virginia. After about 2 years, it got black mold spots. I stumbled upon Corte Clean online. Corte Clean is the best thing I have bought to clean it. I have now been using it 3 or 4 seasons. I use to buy it locally, but just bought it online, as I want the freshest product available.”

“Started using Corte 3 years ago. My trex deck was badly stained. It took a little longer the first couple times I cleaned but now it’s much easier. Your helpful hints each year are very helpful. Appreciate your reminders. I use Corte twice a year as you say and my deck looks great. A Great product. I’ve recommended it to several people. Thanks”

“I can't review the product yet. Not until I may need to use it. Right now I am just reviewing the customer service. Talked to Greg the owner. Told him the stains on my Trex deck and before automatically selling me his product he suggested other means of cleaning that may resolve my issues before I spent money on his heavy duty cleaner. It's good to know there's still some quality customer service and honesty in this country.”

“We've had a Trex deck for approximately 10 years in Illinois. We had used other products in the past. We use to buy Corte Clean locally, at a hardware lumber store. They stopped carrying it??? I went online and now buy it directly. It is fresher and works better. We have alerady cleaned our deck this spring. I just bought it for a teacher friend with a dirty moldy dirty deck and am going to help her clean it.”

“My Trex deck and vinyl fence is in Philadelphia. They get mold. I have previously bought and used numerous bleach products. Don't use them, they don't work! Don't waste your time. Corte Clean works miracles, not just on Trex, but vinyl too. I tell everyone about it. If it doesn't work for you, you are improperly using it. I have been routinely using this product for years and have bought more to again clean my composites.”

“I have a timber tech gray composite deck with white azek custom made large flower boxes. I have used the Corte Clean product every spring since I built the deck before I take out our outdoor furniture and accessories. After the fall and winter here in southern Connecticut the deck and flower boxes have green algae stains and are very stained from the falling leaves. This product works outstanding, as long as you follow the instructions. It does not harm our Koi in our pond which is located right off of our deck or my wifes numerous flowers surrounding it. It its well worth the investment. I am a Corte Clean user for life !!! Give it a try I think you might be surprised with the results..”

Our neighbors have come over, that too have the decking, and wonder how we keep it so clean. I showed them the bag of Corte Clean. They all now use it too.

Thank you for the testimonial. Fortunately, Corte Clean generally takes less time than using multiple cleaning products, while costing less money and does not have the risks of using non-compatible chemicals that can produce toxic, poisonous gas. Once neglected composites are cleaned and the underlying tannin issue with the wood fibers and/or dirty recycled plastic has been cleaned, it should take approximately 2/3rds less time to apply and a lot less effort and up to 1/2 the Corte Clean, especially if one applies before it rains, at the "routine cleaning" strength "at least twice yearly, spring & fall, or when stains appear" to keep composites clean. One mixes the Corte Clean, sprays on "When Corte Clean no longer turns 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 composite prior to using." Proactively applying prior to the composites receiving natural moisture from rain or snow to "thoroughly rinse" eliminates time & effort. Please call if you wish to thoroughly discuss.

“We have a 5 year old Trex deck in Baltimore, Maryland. It gets the black mold spots! We have tried many other products without success. We now can't live without Corte Clean. We routinely use it to keep the deck clean. We can't live without it. We love it so much, we have given it to my parents and friends that own composites as a gift.”

“Our composite deck was badly stained from years of neglect. The deck was stained with barbeque grease, mildew, planter rings, and organic material (leaves, bird droppings, etc.). We tried cleaning with a mild detergent which did nothing. We tried a power washer which started to damage the material. I bought Corte-Clean as a last hope of restoring our deck. Used as directed, it delivered as promised. I could not believe the difference! Even the barbeque grease stains were significantly improved. Corte-Clean does not promise to remove every stain, but it was definitely worth the money. I will continue to use this product and just purchased it for the second time to treated the rest of the deck.”

Wow! Your composite deck was a mold stained NEGLECTED mess! All stains will generally come out. Made sure you do not skip any Corte Clean label direction, especially the one that states "Rinse with water. Water magnifies stains. If stains are still visible, repeat application process. Composites that have tough stains, been NEGLECTED, or previously cleaned with other products and/or sealed may require several applications & additional Corte Clean." which you unfortunately need to complete the job. The Corte Clean label directions then go on to state "When Corte Clean no longer turns 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." By following these label directions, your composite deck should be 100% stain free. If Corte Clean won't remove the stains, they are likely permanent, however, your deck doesn't appear to have any permanent stains Corte Clean won't remove by following these steps. Failure to follow these steps will likely result in stains returning sooner rather than later. To show our appreciation of your review, especially with pictures, we want your deck to look 100% clean and are sending you FREE Corte Clean to complete the job. Once you get your composites thoroughly Corte Cleaned, please consider proactively using "Corte Clean at least twice yearly, spring & fall, or when stains appear to keep your composites clean. We would suggest using Corte Clean 3 or 4 times per year for the first year or two to keep your neglected composites clean. If stains are returning, you are waiting too long to Corte Clean. The goal is for your composites to stay clean for longer & longer for less & less. It is best to proactively use Corte Clean at the "routine cleaning" strength before it rains so the natural moisture can "thoroughly rinse". The trick then becomes to see how little Corte Clean can be proactively used, how little money can be spent, how eco responsible one can by using less Corte Clean be to keep your composites Corte Cleaned, not just of mold stains, but all common stains. Please call if you wish to thoroughly discuss.

“We have had a Trex deck for over 12 years. Corte Clean is the only thing we have ever used to clean it of mold and dirt in Indiana. I love that I have never had an issue with my plants surrounding the deck. I would like to use it 2X per year but lately have only used it once per year. The product works so good that I have recommended it to my cousin.”
