About Corte Clean Composite Deck Cleaner:

DISCATISFIED CORTE-CLEAN® CUSTOMERS (anything less than a 5 Star Review)!

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 are a small, 1 product, family run, American made business. We will do our best to help you, as we are EXPERTS in composites & keeping them clean.

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"!!!

“We tried another brand that is available at home improvement stores and it did not work at all. We used Corte-Clean and with almost no scrubbing it cleaned the deck. Amazing.”

“I have a TimberTech deck in PA facing west. It is installed perfectly, facing west, so it took about 6 years for it to get mold. I tried other products and scrubbed my ass off. They never really worked and the mold rapidly returned. I then discovered Corte Clean at Lowe’s. This product works like stated. I have been using it for years and now buy it direct, from its website, and just again purchased. It sure is nice to get what you pay for and the deck stays clean for longer. I wish my buddy who had been using Corte Clean would have told me about it, instead of waiting for me to discover it!”

“I have three large Trex decks that were a nightmare for mold right from the start. Trex customer service would not help at all. I initially tried bleach based Olympic Deck cleaner which lightened my new deck and didn't last long. I found Corte Clean on- line about 8 years ago and followed the directions to success! It is an awesome product that really works and makes my huge investment in composite decking worthwhile. Also the customer service is top notch as they will help you with any deck cleaning problem you are having.”

“My large, multi-level deck is 11 years old, and I have used Corte Clean for many years because it was recommended by Timber tech. It has kept our deck looking like new. I tried a liquid product last year because the store said it was easier to use- the deck looked clean for only 3-4 weeks. I am now using Corte Clean proactively twice a year, which is quite easy, and the deck stays free of stains year around. This method was suggested by the Corte Clean staff- great customer service!”

“7 Year old Trex deck installed in 2011 in Virginia. It gets moldy, greasy and rusty. Corte Clean is the only product we have ever used that cleans it all and keeps it clean. We just re-ordered and are happy with the product.”

“I have a 12 year old Trex two tiered deck and have been using Corte Clean ever since it was installed to clean mold, grease, oil, rust, etc. For a few years in between, at the beginning, I have tried other products that the Trex Company recommended without the same success, as they were available locally at Lowe’s, Ace, etc. I tried them because I was in a hurry. They smelled so horribly of chlorine, the neighbor came over to complain! These products never really worked. Nothing else works quite like Corte Clean and I will never again use anything else again.”

“Best damn cleaner on the market. Blew my mind. For 12 years have been trying to clean ALL THE DIFFERENT KINDS of stains from our composite deck ( Timber Tech ) with different deck cleaners from Home Depot and Ace to name a few. Finally after using Corte-Clean and FOLLOWING the instructions we have a new looking deck. Had I known what was to follow I would have taken before and after pics so I could blow your mind. Thank you from a new lifetime user of your product. Loudon ,Tn”

“It cleaned my Timbertech uncapped decking very well. I had bought CorteClean last Fall, but waited for this Spring to clean my two year old deck. I was very pleased with it's ease of use. I have a small deck, so I used just 3 scoops of cleaner in a 1 gallon of spray bottle. I used a hand brush lightly after about a ten minute soak. Very happy with the results!!”

“OMG!!!! Corte Clean is amazing. We have had major problems with dark stains on our composite decking. We have tried 5 different cleaners and nothing got rid of them. I was getting frustrated because lets be real... composite decking is not cheap and ours looked dirty and gross. Then I found out about Corte Clean. So I figured Id give it a shot after reading and seeing before and after pictures on the website. I am estatic how well it cleaned my deck. My deck looks brand new! Ordering again to be prepared for a fall cleaning. Thank you, thank you, thank you!!!”

“I've been using Corte Clean Deck Cleaner for five or more years, I've lost track. I use it in the spring after the pollen season to get the winter stains from the deck. I was first able to buy Corte Clean locally but now order it direct since no one carries it here. Corte Clean is the best product I have ever used to make my deck look like new. It really lifts the stains from my Trex and protects it for the rest of the season. The product requires thorough mixing or it will jam your Hudson-type sprayer. I've learned to use a paint stirrer that fits on a drill for best results. Be sure to keep the treated surface wet for at least 20 minutes for best results. I use a power sprayer to remove it although Trex recommends against this. I also treat an area larger than 10' x 10' but keep it damp especially in the sun. It works for me and makes the job go quicker. I highly recommend Corte Clean and will use it for years to come. Just wish I could buy it locally. However, shipment from the company was quick and timely.”

“We have two composite decks, at two houses. One is along the California coast and one is not. The 9 year old TimberTech deck, with hidden fastiners, is on the coast, which gets lots of morning dew, due to the fog resulting in green and black molds. The grey Trex is inland and stays dry most of the year, but still gets dirty and moldy over the winter. Corte Clean works great for cleaning both. The mold use to grow up from the deck around the built in BBQ, onto its cover, damaging it. I sprayed the Corte Clean on the decking and bought a new BBQ cover, problem solved. Great product which I just ordered more for this season's cleaning. Be sure to use in direct sunlight for best results!”

“We have an older TimberTech deck in PA, where it has been raining for weeks. The installer told us to use Corte Clean, which we use to purchase at Lowe's and have used exclusively for years. It gets rid of the mold. We now purchase it directly and just again bought it for this year. The deck looks brand new when done.”

“Works great for cleaning black mold spots from composite decking. Love that it doesn't hurt the plants. I water them heavily. Been using Corte Clean for years, just purchased again. Not sure what brand of decking, but it was made in here in Green Bay, WI.”

“I have a TimberTech deck that had black mold spots all over it here in NJ. I purchased Corte Clean several years ago and used it. I havn't needed to clean it in at least 2 years because the black spots havn't come back. I'm now getting a little green lichen or moss. I have tried many other products prior to discovering Corte Clean, without the same success. This is truely a great product.”
