I have a composite deck in Wisconsin which I purchased from Menards. It gets mold, especially in the shade. It use to take me 6 hours of power washing to get it clean. It now takes me 10 minutes with Corte Clean. I love that you can see it working when it hits the stains, as it foams up and turns dirty. This is my 3rd year using Corte Clean. While this product is not cheap, it is definitely worth the money. I have recommended it to my brother, whom also purchased a composite deck from Menards. I will say, the first time I used it, I wasn't that impressed, until several days later, after the morning dew, the deck then looked amazing! I will be using Corte Clean spring/fall and just ordered more today. Keep up the good work Corte Clean!

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.

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 am the owner of a restaurant called The Office in Ukiah, California. Corte Clean is the best product ever for cleaning our composite deck & stairs.

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.

Corte clean is amazing! I highly recommend it to everyone. I used other cleaners because I couldn't find anything else and my brother in law recommended corte clean and I couldn't be happier. I thought my deck was stained forever but NO, it came very clean. Pricey but well worth it!! thank you corte clean!!

Corte Clean does the job. I clean my trex composite deck 2 times a year and have very good luck with Corte Clean. I try and keep ahead of the game and Corte Clean does that job. I am very pleased with the product.

I have Trex decking installed in 2009. It gets mold. I have tried many other products. Corte Clean works like magic. It is the only stuff that works.

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.

Got rid of deep embedded mildew in some old trex decking. On newer composite it keeps the black spots from appearing. The new formula even works better.

I have used many different products and Corte clean always works the best. It takes time to apply but is well worth the effort. Make sure the Corte clean is not expired and follow all of the directions You will be happy with the results

Bought this product for my deck in Lakewood, Colorado. This Trex deck had oil, grease, rust, mold, and unknown stains all over it. After using this product the deck looked nearly brand new! I highly recommend Corte Clean composite deck cleaner for any composite cleaning job.

I just tried corte clean for the first time and I am thrilled at the results! I will be ordering more in the spring and plan to follow the cleaning suggestions to clean my deck twice a year. I did very little scrubbing too which was a plus! Thank you!

We routinely use Corte Clean. The mold really isn't that big of a deal any more.

We've tried other products in the past to clean our TimberTech deck in Massachusetts. We now only use Corte Clean. I ordered more today.

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.

We have a Trex deck around the pool in NY that is 6 or 7 years old. It gets grey mildew spots. I love Corte Clean and have used it three times in the past. I have told many people about this great product who now use it too.

I have been using Corte Clean for many years on my Timbertech deck. I'm in Maryland and the mold on my deck is brutal, I use Corte Clean and the product brings the deck back to new. I would suggest using bottled water if you have well water as it dissolves much better.

After only a few years of use my deck had all these ‘stains’ and black spots and was disappointed I bought it. After searching the internet I found Corte clean. I am pleased to say after using this product, going by the instructions, my deck looks like new! Now regular maintenance!
Review by Assanaru Swinbank3 months ago
I have been using CorteClean for nearly 9 years now and it works great on my TimberTech deck. I follow the directions carefully, using in the spring and fall, and it removes the mold and black spots every time! I use to be able to get it at a local hardware store in the next town, but they no longer carry it. Very disappointing. Thank goodness I can buy it directly from Corte-Clean!

Just wanted to share these photos of my deck! After four applications of Corte clean, it looks fabulous!! There is not a mold/fungus spot to be found! I can’t tell you how thrilled and thankful I am to have found you and your product!! I can tell by speaking with you that you genuinely believe in Corte Clean and I’m glad I did, too. After speaking with even professional deck cleaning companies, I had resigned myself to the fact that my deck would be covered in black mold spots. I was literally told they would never be able to be removed!! I am so excited and wanted to share my photos and my satisfaction and appreciation for your time and guidance. Thanks again, you have a customer for life!!

We have a Trex deck in Ohio under a maple tree. It doesn't get much son. Corte Clean works. It is good stuff. 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. I just ordered more for the fall cleaning today.

For years, I use to drive 30 miles to buy Corte Clean. Then, the retailer here in Georgia no longer stocked it? I then started buying it directly from the company. I have been doing this for 4 years. I called today to order more, so this is my 5th. In total, I have been using Corte Clean to clean Trex for almost a decade. The mold doesn't come back any more. I am a very happy customer.

I’ve had an AZEK composite deck for 5 to 7 years. I get black mold and dirt in Illinois. The first year I used Corte Clean to clean my deck, I hired someone to clean it, as I didn’t want to do the work. I now use Corte Clean spring and fall; however I may do it three times this year. Corte Clean is a great product that I have ordered again this year.
