This is the first time in 15 years, I used Corte-Clean to clean my deck. It literally cleaned up all the gunk(bird dropping, algae, oil etc). The Trex flooring looks completely new, shiny and brand new. Happy with the product will use it every year.

I've had ChoiceDek in for well over a decade in Tennessee. I use to use Clorox for the mold, until it really did a number on the plastic. The plastic railing became rough and the deck turned solid black. It no longer worked for the mold. I then tried Corte Clean. It worked perfectly. I have been using it for years, spring and fall. I just purchased more today.

We have been using Corte Clean on our deck for a few years now and don鈥檛 consider using anything else. We have a Trex deck that was built about eight years ago and in areas that don鈥檛 get enough air flow underneath, we get spots of dark mold. The Corte Clean makes such an amazing difference! We clean it in the springtime and along with spraying and waiting the suggested time, we also keep a stiff bristle broom and give the section a little scrub and rinse. It鈥檚 an easy process and once it鈥檚 done, the deck feels so clean and feels good on bare feet. We really enjoy our deck after it鈥檚 cleaned.

We have a Trex deck located in Minnesota that is approximately 10 years old. We bought it because it didn't need to be painted so it would last. After about a year, it started getting black mold spots all over it. We went online and found out Trex was known for this problem. Had I known Trex had this problem, we would have rather installed a wood deck and just painted it. We contacted the Trex company and they were not helpful. We went to Lowe's and discovered Corte Clean. Unfortunately, it was beyond its expiration date, and didn't work! I called the Corte Clean company on a Saturday and they resolved the problem. Corte Clean is the only stuff that got the deck clean. Lowe's no longer carries it, so we order it from the company. We have now been using Corte Clean for 10 years.

I have been using Corte Clean to clean my Trex deck of mold for years and just love it. It got rid of the oil stains too. It's amazing!

I found out about Corte Clean from my father-in-law, who use to own a house with a composite deck. We use to order it together. I have a 12 X 14 second story Timbertech deck with stairs down to the ground level in New Jersey. It has lots of trees around it and gets mold. I take the pressure washer to it to remove them, then use Corte Clean. I do this twice yearly, in the spring and fall. I have been using Corte Clean for 10 years. The deck still looks brand new, excluding where it wasn't properly installed with proper drainage gaps.

We get black mold spots on our composite deck. I have two types of composite decking, as we extended the deck. It's about 400 square feet total in Iowa. This is my 4th time purchasing Corte Clean. I tried some old Corte Clean and it didn't work. I noticed the date was expired from 2018. Fresh Corte Clean works pretty darn good! I just bought two more today.

We have been using Corte Clean to clean our composite deck for 10 years, mostly for mold. My son in Cincinnati uses it too. We are happy with the results.

My husband and I installed a TimberTech composite deck to replace the old rotted out wood deck on our condo in Ohio. We didn't want to have to sand, paint and seal anymore. We were looking for less maintenance. To our surprise, mold showed up, so we bought a pressure washer to clean it. Using it was a lot of effort and didn't get the deck clean! Additionally, we were worried about permanently damaging the expensive decking, as so many of our neighbors have done. Most are now black with mold. Their decks look awful and they cover them with rugs. I called TimberTech and they recommended Corte Clean. I am very happy with the product. We have now been using it for 3 or 4 years. It works so well, I sold the power washer because I no longer need it. I am very happy with the product and the way it cleans.

I've had a TimberTech deck for 12 to 15 years. I bought it at Heartville Hardware here in southern Ohio. It gets black and green mold because its on the shady side of the house. The first time I used Corte Clean, I was sold. The deck looked like new. It also works great on my concrete driveway.

I used Corte Clean for the last 10 years. The absolute best composite cleaner on the market. Last year i didn't plan ahead and the local stores were out, so i tried another product. Big mistake. I ended up online and ordering the REAL DEAL Corte Clean. I clean the deck twice a year because it looks so awesome and makes it look new again. Thanks Again for such a great product.

We have an expensive large Fiberon Horizon PVC coated deck we installed approximately a decade ago here in Kentucky. It's actually 3 decks, on 3 levels, with stairs handrails, balusters, etc., around 400 square feet total. It is the textured decking that looks like wood with deep grooves that traps dirt and derbies. It gets real dirty and difficult to clean. I tried another product, but it excessively bleached and permanently damaged the deck! I can still see where I used it today, which makes me mad. I called the manufacturer, Fiberon, and they recommended Corte Clean. It is awesome! It is easy to use. You can see it work. We have been using it ever year since we found out about it. I use to buy it locally but now buy it directly form the website. I don't mind this, as it is fresher & works better. As long as we own this deck, and live in this house, we will be using Corte Clean to keep our deck clean. God bless you.

We have used corte clean for years and have always been pleased with it! And we always clean our deck twice a year because our rear of the house faces north and cedar trees around it. Glad to see we can still order on line.. sincerely Bill

I have a 2,500 square foot TimberTech composite deck in Toronto Canada. I installed it in 2015 or 2016? No one told me it got moldy when I bought it, especially on the north side of the boat house! I tried the sodium hypochlorite chlorine bleach based products. Don't waste your time! After doing a lot of research on the internet, I finally found Corte Clean. It was the only website that explained the problem as it relates to the wood fiber tannin's and molds. This was the deciding factor in going with Corte Clean. Unfortunately, there wasn't a retailer near me, so I drove approximately 2 hours, each way, to the 84 Lumber in Buffalo, NY. They only had 2 bags of Corte Clean or I would have bought more!!! I took them home & used them. The label directions are crystal clear. This is the only product that works. I know a lot of people with composite decks and will be recommending this product. I just ordered 8 more to complete the job this spring. Thanks Corte Clean!

The composite deck had been in place for 10+ years and never cleaned. It was it pretty bad shape!! We used the Corte Clean on a cloudy day so we could allow it to soak for the recommended time without drying out. The deck isn't perfect, but the difference is AMAZING. Very little scrubbing, very little effort and the deck looks so much better. We truly were not sure what to expect as this deck was in bad shape. Still a little more work to do, but I believe with another cleaning this Spring, it will look GREAT. Very pleased with the results. FTM: Dover Delaware

Corte clean did a fantastic job cleaning my deck. Although I still had a few residual stains after cleaning, they were much lighter than they had been and overall the results were better than I had ever achieved in the past 15 years of owning the deck. My primary concern was black mildew stains that were almost completely eliminated. The mildew staining under my grill mat was so improved that I got rid of the mat. Grease stains were reduced but required other cleaners to get to my satisfaction. I wouldn't give Corte clean five stars for its cleaning ability and the great customer support I received. The reason I gave the product for stars was because there are a couple matters you need to keep in mind when using Corte clean. Corte clean insists that you follow the instructions carefully. This means af fair bit of prep work and also that you apply the product during the appropriate weather conditions. In my area, which is Maryland, having the necessary warm weather without rain, so it can be a challenge. so it's a waiting igame to be able to clean the deck. Also, application of the product is not as simple as spray and wash it off. It requires care where you put it down, protecting plants around the deck, and scrubbing the deck well while it's still wet. It will take time but the results will be worth it.

I live in Tampa Florida and have an EverGrain composite deck, which was installed years ago. I, like everyone else, get black mold stains. I have tried all the cheap products sold at Home Depot and Lowe's. Most just excessively bleach the color of the deck and don't get rid of the mold or last. I then tried Spray & Forget with no results. I called the company and they told me it would take up to 6 months to work. I told them I didn't want to wait till after Christmas for my deck to be clean or buy the company. I then tried Once and Done, which only lasted for a minute. Needless to say, I had previously used Corte Clean and you get what you pay for. I just ordered more and won't be again wasting my time or money with anything else.

Tried a couple other products that were just bleach. I was surprised after using Corte Clean the first time that it brought the color back.

We have a large Trex composite deck and, over the years, tried pretty much every cleaning product out there, with less than satisfactory results. We tried Corte Clean this year and found it to be the only product which could "get the job done" with regard to removing both black and green mold and other stains. Our deck has gone from unsightly to looking "like new", simply by following the Corte Clean directions and applying the product at the recommended intervals. Corte Clean is a product which does exactly what the manufacturer states it will do. We'll never even consider using anything else.

I have a Trex composite deck in Ohio on the back pouch that is 5 X 10 with steps that has been installed for 5 years and been using Corte Clean spring and fall to keep it clean. It has worked very well. I buy it at 84 Lumber.

I have a Nexwood composite deck with white vinyl railing that was made in Canada. I installed it in 2004. The manufacturer no longer exists. It is approximately 18' X 25' raised above the ground with two platforms and lots of steps. My deck was a mess! I barbecue on it year round, including the winter. It had grease, oil, rust, mold… You name it, it was stained. I was about to replace the deck, as it was that bad. I thought nothing would get it clean. I bought Corte Clean last year and couldn't believe how well it worked. It did take some time to clean, however that was to be expected, as I worked small sections. Honest to god, it now looks brand new. I just bought more about a month ago to keep it clean this fall and/or again in the spring.

Our Timbertech deck was installed in MN in 2007. It began to get black mold. Perhaps the ash trees around it had something to do with it? I used Corte Clean for the first time last year. It really cleaned it up. I have ordered more today to do a fall cleaning.

I have been using Corte Clean for years to clean the veranda made of Trex on my house. This product removes the barbecue grease and oil, rust from the cast iron bench, in addition to the mold. Not only does it work on the decking, but on the vinyl siding and cedar roof shingles to clean mold. I put it on in the spring and fall, especially the fall on the north side of the house. The rain and snow rinses it. It makes these items look like new.
