“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.”

“Corte Clean is the only composite deck cleaner that I have found that will properly clean a composite deck. Multiple applications is required for tough stains, but it works.”

“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”

“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!”

“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.”

“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 .”

“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!”

“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.”

“The product worked very well as advertised. It cleaned my TimberTek deck using a power washer as well as the PVC rails. I would recommend it.”

“I just cleaned my deck so I cannot say how long it will look good, but this stuff did a great job in cleaning my deck. It got older stains off and algae that had been on there for several months.”

“My composit deck was in terrible shape with stains from a wide variety of sources. I followed the recommended directions and what a wonderful surprise. An almost clean deck. After one application the years worth of stains have significantly deminished. I want to follow up with a second cleaning. I believe, from what I have already experienced, that my eight year old deck will look as new as the day I finished building it. I wish I had taken some before and after pictures. Oh well. What I am going to do is order two more bags. Then I will reorder in the fall. Great product! I am a satisfied customer.”

“The pictures on the web site were impressive but I found them hard to believe. We live in the Northwest where it rains at least half of the year, and our deck is almost completely shaded by large trees, so moss and mold are a given. For two years I tried so many things to clean the moss and mold off of our deck, and none of them worked very well. I was always left with black spots. We don't know for how many years the deck was neglected before we bought our home, but as you can see from the photo, by spring it is really a mess. I bought Corte Clean out of sheer desperation and as a last resort before just replacing the deck. I added 4 scoops of Corte Clean to a gallon of water (nearly maximum strength), sprayed it on, and scrubbed the deck with a deck brush. After 20 minutes, I thoroughly rinsed it. When it dried, we were shocked to see how clean it got. It was a miracle! It was like getting a new deck. I never would have believed it if I hadn't done it myself. I can't recommend Corte Clean highly enough!”

“Great stuff especially for first generation composite decks. We put our deck in, in 2005 and we have tried every thing you can think off to clean it and this is the only thing we have found that really works. Be sure to follow directions and buy fresh product!”

“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.”

“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.”

“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!!”
