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 wish to help! (415) 924-9500 X 1
Please leave a message if we fail to answer the phone.
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"!!!

“My composite deck is a mixture of TimberTech & Trex. It is located in Ohio. I have been using Corte Clean for 8 years to keep it clean of mold, spring and fall. Unfortunately, this year, I missed the spring cleaning, but have just ordered more to clean it.”

“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.”

Thank you for the testimonial. Fortunately, Corte Clean generally takes less time than using multiple cleaning products, while costing less money and does not have the risks of using non-compatible chemicals that can produce toxic, poisonous gas. Once neglected composites are cleaned and the underlying tannin issue with the wood fibers and/or dirty recycled plastic has been cleaned, it should take approximately 2/3rds less time to apply and a lot less effort and up to 1/2 the Corte Clean, especially if one applies before it rains, at the "routine cleaning" strength "at least twice yearly, spring & fall, or when stains appear" to keep composites clean. One mixes the Corte Clean, sprays on "When Corte Clean no longer turns dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces. Corte Clean is designed to continue to clean any time it receives moisture. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse composite prior to using." Proactively applying prior to the composites receiving natural moisture from rain or snow to "thoroughly rinse" eliminates time & effort. Please call if you wish to thoroughly discuss.

“We have a 5 year old Trex deck in Baltimore, Maryland. It gets the black mold spots! We have tried many other products without success. We now can't live without Corte Clean. We routinely use it to keep the deck clean. We can't live without it. We love it so much, we have given it to my parents and friends that own composites as a gift.”

“Our composite deck was badly stained from years of neglect. The deck was stained with barbeque grease, mildew, planter rings, and organic material (leaves, bird droppings, etc.). We tried cleaning with a mild detergent which did nothing. We tried a power washer which started to damage the material. I bought Corte-Clean as a last hope of restoring our deck. Used as directed, it delivered as promised. I could not believe the difference! Even the barbeque grease stains were significantly improved. Corte-Clean does not promise to remove every stain, but it was definitely worth the money. I will continue to use this product and just purchased it for the second time to treated the rest of the deck.”

Wow! Your composite deck was a mold stained NEGLECTED mess! All stains will generally come out. Made sure you do not skip any Corte Clean label direction, especially the one that states "Rinse with water. Water magnifies stains. If stains are still visible, repeat application process. Composites that have tough stains, been NEGLECTED, or previously cleaned with other products and/or sealed may require several applications & additional Corte Clean." which you unfortunately need to complete the job. The Corte Clean label directions then go on to state "When Corte Clean no longer turns dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces. Corte Clean is designed to continue to clean any time it receives moisture. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse prior to using." By following these label directions, your composite deck should be 100% stain free. If Corte Clean won't remove the stains, they are likely permanent, however, your deck doesn't appear to have any permanent stains Corte Clean won't remove by following these steps. Failure to follow these steps will likely result in stains returning sooner rather than later. To show our appreciation of your review, especially with pictures, we want your deck to look 100% clean and are sending you FREE Corte Clean to complete the job. Once you get your composites thoroughly Corte Cleaned, please consider proactively using "Corte Clean at least twice yearly, spring & fall, or when stains appear to keep your composites clean. We would suggest using Corte Clean 3 or 4 times per year for the first year or two to keep your neglected composites clean. If stains are returning, you are waiting too long to Corte Clean. The goal is for your composites to stay clean for longer & longer for less & less. It is best to proactively use Corte Clean at the "routine cleaning" strength before it rains so the natural moisture can "thoroughly rinse". The trick then becomes to see how little Corte Clean can be proactively used, how little money can be spent, how eco responsible one can by using less Corte Clean be to keep your composites Corte Cleaned, not just of mold stains, but all common stains. Please call if you wish to thoroughly discuss.

“We have had a Trex deck for over 12 years. Corte Clean is the only thing we have ever used to clean it of mold and dirt in Indiana. I love that I have never had an issue with my plants surrounding the deck. I would like to use it 2X per year but lately have only used it once per year. The product works so good that I have recommended it to my cousin.”

“We previously had a Trex deck for 7 years. We lived on a rain forest in British Columbia. Moss and algae were a major issue. Corte Clean got everything out of the grooves and left us with a pristine like new deck. We recently built a new home and installed Trex decking. We will be getting more of the Corte Clean as this is the best product we have found for cleaning composite decking. The instructions and process are easy to follow and it cleans quickly and efficient. Thanks for making such a great product!”

“My Trex deck is about 12 years old. I did not know that it could get mold... black spots. Trex was being marketed as “no maintence decking” at the time, if I recall correctly. So what was happening and how would I address the problem? A google search eventually led me to Corte Clean and after trying it and seeing the results, I am just so grateful to have discovered this product! I have been using it for years. I live in the northeast and have discovered that the best time for me to clean the deck is at the end of May, when the morning reaches at least 65 degrees and is sunny... but the humidity is low. I can get it done much more quickly. I have also started using a more diluted cleaning in the Fall. The results are that the deck is not as problematic in the Spring. This is a wonderful product and the service is always very friendly and helpful when I call. ALWAYS buy a fresh bag before cleaning. If you don’t, it will not work as well. And if you do, it will do the job VERY well!”

Thank you for the testimonial! You WIN a FREE 2000A Corte Clean bag + FREE SHIPPING. Please call when you need it. Yes, using FRESH Corte Clean and not skipping the FALL cleaning is critically important, especially with your generation of Trex. Unfortunately, most weren't aware that the Trex Company recommended "spring and fall" cleaning for "Mold and Mildew". Corte Clean was designed to be used "at least twice yearly, Spring & Fall, or when stains occur" because it cleans all common stains, not just those caused by molds (mildew is a mold and not common on Trex), therefore, most never notice grease & oil, rust & tannin's and other stains. When Corte Clean is properly proactively used, at the "routine cleaning" strength, so Trex owners can generally save, by generally spending/using less, which makes it more ECO RESPONSIBLE, when it rains or is thoroughly rinsed, stains just disappear, however it may not have that instant WOW cleaning effect. If stains are coming back, one is generally waiting too long to proactively use Corte Clean, especially with Trex or other composites made from recycled wood & plastic that are located in moist climates.

“This is a long story... I have a 5 year old Trex deck. Trex does not tell you how really ugly the deck gets and how hard it is to clean. Many people of complained about this. Last year I discovered this wonderful product and have not been happier. The first cleaner I used was recommended for composite deck and was a chlorine based product that was super expensive, la or intensive and solution expired in 30 days. It also did not get out all the mold and mildrew. I should mention I live in western Washington and it is wet here. Okay. So I get my little bag of Corte Clean and think how in the world is this going to be enough to get my deck clean. I pout the powder into my sprayer and spray on. Leave it on for 30 minutes and then wash off. I did scrub a little bit on tough spots. Now I noticed there were still stains and was a little disappointed but low and behold it rained a couple of days later and deck was cleaner. Consequently each time it rain the deck improved. I was pleasantly surprised. I even sprayed products on my Hardiplank siding and fence and it worked wonderfully. My neighbor put in Trex and had exact same problem....no other composite deck cleaners work as well as Corte Clean. I only wish that Trex would have put that information ontheir website when I was researching composite decks and cleaners. The key to happiness with this product is reading the directions and waiting for deck to vet wet in my case by rain which reactivates the product. Best of luck to this company and customers. Thank you for listening.”

Thank you for the Trex testimonial! The previous use of the product you have used, or any sodium hypochlorite based product, does unfortunately generally result in it taking more time for Corte Clean to remove mold stains. This is why it is critical not to skip the final Corte Clean label direction. You win a FREE 2000A bag of Corte Clean for recommending to your neighbor and discounted Corte Clean for future orders. Just call should you need more.

“We have owned the lake home with an AZEK composite deck for 10 years in MN. The trees were dripping sap all over it. Nothing would remove it. I called Corte Clean customer service and they told me to use it at 2.5 scoops per gallon of water. I watched the YouTube Corte Clean video, which everyone should watch before using this product. It was absolutely wort the 6 minutes. I applied the Corte Clean, watched it bubble up and the sap stains disappear. I will be proactively using Corte Clean in the future. I couldn't be more thrilled! The product is simple and easy to use and the customer service is excellent! I will be recommending to my local hardware store and anyone whom owns a composite deck.”

“We have had a composite deck for about 10 years. I was under the impression when we went to the expense of putting in composite material that we would not need to clean it....wrong. We tried several products from box stores with no luck until we found Corte Clean. It removed mold spots and stains from leaves and grease from the grill. We’ve been using it ever since. The product is easy to use and works wonders with seasonal grim.”

Now the goal is to make sure your deck remains looking this way, for the lowest possible cost, with the least amount of time & labor, while being as eco responsible as possible, by using the least amount of Corte Clean. Proactively using Corte Clean “at least twice yearly, spring & fall, or when stains occur” at the “routine cleaning” or up to ½ strength is the key. Please call if you wish to thoroughly discuss, as no one wants to waste time & money cleaning anything, especially composites.
