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 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"!!!

“I thought I was going to have to rip out my Evergrain composite deck, and replace it to the tune of $6,000 or 7,000 dollars! It was a mess. Mold and you name it. I talked to Corte Clean customer service, purchased Corte Clean and cleaned my deck last fall. To my surprise, and more importantly, my wife’s, it is still clean this spring. Regardless, I just completed my spring application of Corte Clean to keep the deck clean, as we are about to get 2" of rain here in Wisconsin after a miserable winter and spring so far.”

“I’ve had my TimberTech deck for 9 years. After the first couple of years, it got black mold all over it. This is to be expected here in Wisconsin. I have been using Corte Clean to clean it for 6 years. I just called and ordered.”

“I just re-ordered Corte Clean. I have been using Corte Clean to keep my Trex deck clean of black and green mold for 4 or 5 years. It gets especially bad under the railings and in the other shaded areas here in Virginia. Corte Clean even cleans the mess under the barbecue too.”

“We installed our supposed no maintenance expensive Trex deck 5 or 6 years ago. Within a year, it started getting black spots all over it. I had no idea what it was. I tried several deck cleaners from the local stores. Nothing worked. I then went on the internet and searched. I found Corte Clean, called the company and they explained what was going on, with the black mold and how to clean it and keep it clean. I purchased the Corte Clean and cleaned my deck. It took a more time and Corte Clean, the first time to get clean. I could see all the dirt and mold coming out of the deck. The black spots disappeared. I now proactively apply Corte Clean in the spring, middle of summer and in the fall or when my deck starts to look dirty. This requires one bag of Corte Clean per year to keep my deck clean. Here in Minnesota, we just received two feet of snow two weeks ago, which has since melted, after a long winter. My deck doesn’t really look that bad, but I just re-ordered Corte Clean for the spring cleaning, which I generally do at in April or May when the weather permits. Corte Clean is a great product for keeping Trex decking clean.”

“I have a Trex deck that gets mold and other stains, especially on the stairs. I use to purchase Corte Clean locally, here in St. Charles, IL but no longer can find it. I tried the other products from Lowe's, Home Depot, Menards, etc., some that the Trex Company recommends, without the same success. The mold comes back within weeks!!! Some also color fade worse than Corte Clean. I guess they want to sell what keeps you coming back to the store. I just purchased Corte Clean directly from the company. Great product.”

“I have been using Corte Clean spring and fall since we installed our TimberTech deck 10 years ago in Michigan. I just re-ordered. It keeps our deck clean of black mildew spots and other stains. Our deck looks like new.”

“Corte Clean works AMAZING on TimberTech! I just re-ordered. In Mass, our deck turns green and gets dirty. I have tried other products from the box stores, such as Home Depot & Lowe's when I wasn't willing to wait for shipping or not available locally, and nothing comes even close to Corte Clean.”

“We live in a townhouse with 72 units in Illinois. We replaced our deck with Trex 7 years ago. Corte Clean works great in keeping it clean. It looks like new. I just ordered more so our son can clean it when it stops snowing. We tell everyone in our community about Corte Clean.”

“I have a Trex deck which was installed in approximately 2001 here in Kenmore, WA. We get lots of rain. This winter I think we have had only 3 or 4 sunny days. My Trex deck gets green with mold and other stains when I neglect it. I have been using Corte Clean for years to clean it. It works! I just re-ordered and will be proactively using it to keep my deck clean. I just installed a new composite deck, not Trex, from Home Depot. We will see if I need Corte Clean to keep this deck clean too?”

“I have an approximately 10 year old TimberTech in Michigan. I have tried the Olympic Deck Cleaner, but noticed the mold getting worse, especially in the shaded areas. I then tried Corte Clean. I just returned from Florida and it is time for the spring cleaning, which I have been doing for years. I just re-ordered it for the spring cleaning. Great product. here it is.”

“By far the only thing that will work, due to my deck being 15 years old, and never has been cleaned,I will have to do again this fall, the amount of dirt and mold that this product took off was amazing.”

“I've use Corte Clean for about 4 years and it really brings my deck back to life after a miserable Chicago winter. I spray it on and let the rain activate the cleaning process. Using it 2x a year really keeps it looking great. If there are a few dark, moldy spots left after the winter, I give them another shot and wait for the rain, unless I'm really impatient. That one time I just sprayed it on again, let it "work" for a few minutes, and then used an old push broom to brush over them. However, since I'm basically lazy and would rather do something else - I just pop a suds and wait for the rain.”

“long time to receive the order.”

Thanks for the Corte Clean review! It generally takes 1 to 5 business days for Corte Clean to be delivered via FedEx Ground in the Continental United States. If you are on the East Coast it generally takes 5 business days (See FedEx Ground Map for delivery times on the Corte Clean website from which you purchased). If we could ship it faster, we would. This is generally just enough time to properly prep composites prior to Corte Cleaning. Planning ahead and pre-purchasing is highly suggested, “at least twice yearly, Spring & Fall”, as most composite manufacturers recommend and Corte Clean was designed and intended. Please let us know if you have any further questions.

“The product worked as advertised on my TimberTech deck and stairs. I just followed the directions on the packaging as well as the website and it worked! My deck and stairs look like new. I wish knew of this product before wasting time with other products that did not even come close to cleaning my deck with three times the effort.”

If only every customer that used Corte Clean "just followed the directions"...

“I have a 5 year old Trex deck here in Florida. I used to buy Corte Clean at Lowe’s but now buy it direct, from its website. I have noticed that the fresher Corte Clean is, the better and faster it removes stains. The Best If Used By Date is incredibly important, and I get the freshest product when I order it from its website, unlike when I purchased it at the retailer. This saves me time. I have noticed that with proactive use, my deck stays clean for longer periods of time, so I proactively use this product four times per year. I don’t mind paying for products that work, and this one does, as I have tried other products. I just ordered more, as we received incredible amounts of rain with hurricane Irma and it is again time to clean my deck.”

Thank you for your 5 Star Review and pointing out how critically important the Corte Clean “Best If Used By:” date is, when purchasing at retailers, using the product proactively, as it was designed and intended, when the composites have received rain, which results in fungus stains if spores exist. Proactively applying Corte Clean, preferably before it rains, to remove loose spores, before they root and cause stains is always best. Corte Clean is no longer available through Lowe’s, but is available through many other retailers or directly from its website.
