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.

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"!!!

“Joe from uniontown Pa. I have used corte clean ever since I had a timber tec deck installed eight years ago. This is the only product that really cleans my deck. A composite deck is not maintenance free. It does grow mold and mildew and corte clean is the product that gets it out. I give it a 10. Would recommend it to all.”

“Good stuff. Got deck very clean. Had let the deck go too long. Back to new now.Never used any of the Big Box suggestions, but did use the lumber company that sold decking (C Clean) suggestion Tom PIA”

“I live in the extremely rainy, mossy and mildew growing Northwest. Over the years, I've tried many products formulated for decks, but none made much of an improvement in the appearance. However, after an application and good cleaning of our Trex deck, Corte Clean produced was the best result I've ever obtained. Some visual permanent staining from years of inadequate cleaning are still seen, but very inconspicuous. And cleaning the second spring was much, much easier.”

“Corte Clean is super easy to use and incredibly effective! My 15 year old deck had never been cleaned properly and it now looks like new!”

“Have a 3 year old Trex "Enhance" deck about 15% of which was markedly affected by animals and leaves from the tree canopy overhead. The remainder of the deck, though no where near as bad, was still in need of a cleaning this spring. Purchased Corte Cleaner based on the reviews and followed directions on package and your website. Was amazed at how quickly the deck was cleaned. Your product performed as advertised. I have ordered enough for the rest of this year and next. I will not even look at a substitute. Apply at the stronger concentration and rinse the area repeatedly to avoid any residue. A good pump sprayer, long-handled brush (together with any other brushes to get in odd nooks) and pressure washer are all the major tools you will need. Both the lightly and more heavily stained areas now look alike. My neighbor even commented on how much the deck now appears brand new! Couldn't ask for an easier project. About 3 hours for a 1000 sq ft deck.”

“Deck was really dirty and full of black spots . Corta Clean spiffed it up and looks so much better. We should have gotten to it last year but better late than never. We used Corta Clean a few years back as we purchased it from Costco. Now, the only way we can purchase it is directly on line. The product works and so we will order it again . Great product .”

“Used it again to remove mold spots from timbertech. Worked great. There were a few stubborn spots that did not come off and were in a well traveled walkway. While the deck was still wet I sprinkled some of the powder on those spots, waited a while and scrubbed with a brush and the spots were gone. Great product. I'll be using it again fall.”

“I have been using Corte*Clean Composite Cleaner - 2000A for about 8 years on my Trex deck. Corte*Clean works better than any other cleaner I have used. If you follow the directions exactly and don't take any shortcuts, you will be amazed with the results. It is important that your deck be completely dry and in direct sun before you begin. Also, clean a small section of the deck at a time and keep it wet with the Corte*Clean solution until it has time to work. Then rinse thoroughly. For me, Corte*Clean is the best choice.

“I have a Trex deck about 6 years old. After about one year I notices alot of black spots on the deck. Did some research and determined it was black mold. Googled the problem to get a solution and called Trex as well . I didn't want to use all the bleach products out their which I felt were unsafe after reading their warnings on the packages in the home stores. Then i went through the list of products that Trex recommended. One of them was Corte-Clean. I ordered 3 containers as they were not sold in bags at that time. I really had to work at it as the mold was really bad. After 2 applications it was much better but not as good as new. I called Corte-*Clean and spoke to Greg, who I believe is the owner. He made some suggestions and the next weekend I gave it one more shot. Big improvement and I was very happy. The next year the mold was back but not as bad as year one. I did 2 coats this time and I was very satisfied. Don't believe anyone who tells you Trex is "NO " maintenance. Fast forward to 2 years ago. I wasn't feeling 100% and did just one application in May. Deck came out really good and I was set for the season. Last year we had a million things going on and only did one application to half the deck. I just went outside today to look at the condition of the deck. I cannot believe their is no mold whatsoever on either half of the deck. The deck is a little dirty but not really that bad considering. I just called Corte Clean and ordered more product for this year. Greg answer ted the phone and we spoke for a while. He said it must be the product has finally gotten into the TREX and gets reactivated when moisture hits it. He gave me a few tips from things they have learned in the last few years, and I look forward to an easy cleaning this year. My advice is BUY this product and follow the instructions to the letter. Call the company if you have any questions or problems and only use the product if the expiration date has not been exceeded. Good Luck Don Heide -New York”

“I have used this product for a number of years! Tried other products one year, but was very dissatisfied with them. Applies easily not time comsuming, and rinses of with just water hose. As for price it's like the old saying, YOU GET WHAT YOU PAY FOR.”

“So, I read the instructions on the website and ordered 2 bags of Corte*Clean for my 600 square foot deck. I installed the Trex 6 years ago and since it was "Maintenance Free" haven't done much more than wash it with soap and water and elbow grease. We finally got decent weather here in northern Illinois (I had a completely dry deck at least) and since it was on the cooler side, decided today was the day to try the product since it wouldn't dry to fast in the sun. I have a 4 gallon backpack sprayer, so I mixed up 4 gallons at maximum strength. As I was using the included scoop, I was surprised to barely get 10 scoops out of a bag. Glad I ordered 2, wish I had ordered 5! I applied it, brushed it, applied again, keeping the product wet on the deck for the 20 minutes. While I was waiting the 20 minutes I sprayed the next section, keeping everything wet. When the 20 minutes was up on the first section, I only had the stairs left to treat. I rinsed the first section off then treated the steps. Got to the rest of the sections on time and had just enough product left to treat the first piece a second time. What a difference! Definitely need to order more next time. I was skeptical but am now a believer!”

“My north facing composite deck in Wisconsin accumulates the usual dirt but much of it also begins to develop a green stain. This product is very effective, relatively easy to use and really does the job. I highly recommend it.”

“Excellent product! I have been using it for the past three years. The product is easy to use and gets the job done. The customer service is excellent and the delivery of the product is outstanding. I would highly recommend Corte Clean. It is a product I will continue to use in order to keep my deck looking like new. One important feature is the product keeps on working in the rain and snow. Great feature!”

“Our deck gets the Northwest intense summer sun and the long, dreary, moldy winter. We also get a big dose of road grime since we live next to a US highway. We needed a great cleaner and Corte Clean is it. So glad I found it on the internet. It shouldn't be a secret!!”

“I've tried quite a few cleaners and it's the only one that works. I buy it every spring as it performs best when it's fresh. Tough spots may require two cleanings. It may not look like it's doing much while the deck is still wet, but give it a chance. Once dry, your deck will look great.”

“I've been using this product since 2008 and always get great results. I use on my composite deck, pvc deck fence and rails, and even vinyl siding. Just have to be careful not to get it on the windows. This product is recommended by the deck manufacturers and that is how I found it originally. Never tried anything else as this does a great job. Customer service is excellent and shipping is quick.”
