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 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"!!!

“Corte Clean is the best stuff. Nothing like it! I professionally clean TimberTech twin finish for an HOA in New York. It gets mold and mildew, etc. I have previously tried other products such as Mold Armor which did nothing. I learned about Corte Clean from the TimberTech website.”

“We have both Trex and TiberTech decking and I use Corte Clean at full strength to clean all of this material each year. It does an excellent of cleaning stains, mold and other stains on the decking material. It works best if you use a brush to scrub the deck after application and rinse when done. A good rain storm will remove any corte clean left after rinsing. I have used Corte Clean for 10 years and I am very pleased with it and the results.”

“I have a 15 year old TimberTech deck. It still looks like new. I use Corte Clean Spring and Fall. Corte Clean was recommended by TimberTech and it's the only product I have ever used. I love that when I call, if they don't answer, I know I will always get a call back. I just signed up for the yearly subscription.”

“We have been using Corte Clean every spring since 2008 and our Trex deck looks as new as when we bought it. It's located in Wisconsin. Corte Clean was recommended on the Trex website. I just signed up for the subscription service.”

“We've been using Corte Clean every year for 13 years to clean our double Trex decks since they were new. It does what we need it to do in moist Virginia. It's a great product! We've never used anything else and our Trex looks almost new when cleaned. We learned of Corte Clean from our contractor and/or in the Trex literature. We use to buy Corte Clean at Lowe's but they stopped carrying it and we have been buying it direct online from its website ever since.”

“I wish I could remember how I found out about Cort Composite Deck Cleaner, so I can thank them for tell me about such a fantastic product. We have a light grey composite deck, which gets dirty and develops small dark spots. This is the only product that has worked, making the deck look like the day it was installed. The photo shows the difference this cleaner makes!”

“I called TimberTech and they recommended Corte Clean when their other recommended product failed in cleaning the green from my deck. The other product was an expensive hassle, as I was having to clean my deck 3 times per year. The green just kept coming immediately back! Corte Clean keeps the deck clean on my condo in Ohio for nearly a year. It looks brand new after I use it. I have now been using it for 6 or 7 years. I just ordered more for the spring cleaning.”

“I have used Corte Clean for over 10 years and have found it to be the best solution to cleaning my composite deck. most of my deck is grey so it is difficult to detect any weathering. I clean it every Spring. I know I should clean it again in the Fall, but I'm too lazy (and cheap)! It would make the Spring cleaning easier. All things considered, I am very happy with this product.”

Thanks for the testimonial! Don't be so "cheap"! It's likely costing you more time, labor & money/Corte Clean by skipping applying in the fall; as most composite manufacturer's recommend & our product was designed to be used. Proactively using Corte Clean at the "routine cleaning" reduced strength (up to 1/2 strength) will generally result in savings, especially if you apply before the composites get deep stains. This has been proven for we'll over a decade.

The more routinely Corte Clean is generally initially used, less & less is generally needed, the longer composites are generally known to stay Corte Cleaned; sometimes for years. It is critically important to get composites thoroughly cleaned of the tannin bleeding issue which with exposed wood fibers and/or dirty recycled plastic can feed fungi! Failure to thoroughly Corte Clean composites of all stains is generally a waste of time, labor & money/Corte Clean. Thanks for the testimonial!

“I tried everything to clean my composite deck, including power washing and various cleaners. I just could not get some of the stains out, including grease (from grill) and mold. I purchased the cleaner and long-handled brush. Using it was able to get most stains out. I have done this for the past two Springs and will do it again next year.”

Thanks for the testimonial! If all the stains didn't come out on the first application, "repeat" the application process at "maximum strength" and DO NOT skip the final label directions 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 anytime it receives moisture. A white residue may remain until thoroughly rinsed(use a brush if necessary). Thoroughly rinse composite prior to using." The best way to thoroughly rinse is to apply before it rains or snows. If your deep stains don't come out, they generally come out over time with routine "Spring &Fall" proactive cleanings over time with problematic composite decks. Please call if you wish to thoroughly discuss. Happy Holidays!

“I must admit two (2) things. This is NOT one of them but, yes, I am from the South and sometimes use more words than might be necessary. BUT, "in the South" is where decks can sour the quickest due to the heat & humidity. So, bare with me here. Or "bar" with me. One, I do squeak when I walk, I am that tight with a dollar. BUT, I am MORE than willing to pay for quality products and/or services within my budget. And I do my homework, often relying on customer reviews and Consumer Reports to try to select a best value. I purchase my hearing-aids at Costco for that reason. Two (2), I have used Corte Clean many in the past. Initially because I considered the good reviews, which are compiled by an independent company, Reviews.io, and found it to be an extraordinary product, AND a good value. After my first use, I relied on my own experience and the results it rendered. Yes, I have tried to cut costs by using some other methods of cleaning, including a soda/vinegar wash. My bad. My deck is composite and 408 sq. ft. in size. It is the scene of MANY family gatherings over the past dozen years during the summer and into the autumn, usually through Thanksgiving. It falls victim to a LOT of spillage from our grand kids and great-grand kids, plus my grilling. Too late for "long story short", but I do HIGHLY recommend the product, which I have to apply about four (4) times per year. Thanks for listening, y'all. James Paul”

“We had a large deck installed on our house in 2013. It's on the North side of the house with some large trees. We tried several methods of cleaning but none worked to our satisfaction. I researched cleaners and found Corte. The deck is Evergrain weathered wood and looks amazing after each cleaning. We have referred Corte to friends. I am getting ready to order more today. Thanks Corte!”
