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’m not a review writer but I was so impressed with Corte clean I had to say something. Deck is 13 years old and I probably cleaned it once maybe eight years ago. It was a mess, you name it, black mold/mildew spots, lichen, moss, you name it. Light gray correct deck. As I filled the sprayer the dogs had to go out, when I came back, the sprayer nozzle was spraying a spot (trigger was locked on accidental) about 4ft in diameter for the couple minutes I was gone. The deck looked brand new! I was amazed. I continued to clean the remainder of the deck and highly recommend Corte clean. I ordered another bag to clean another deck. I’m going to follow the recommended cleaning intervals going forward.

Our Trex deck is along the coast in NJ. It's around 10 years old. I use hurricane Sandy as a benchmark. It turns green with mold. Corte Clean makes it look new, when my son cleans it. We use to buy Corte Clean at Lowe's, but now buy direct. Great product!

This Deck Cleaner is one of the very few cleaning products that delivers on all of its promises. For us, because we let the deck go for 2 years, there was some scrubbing to do, but unlike other cleaners, the deck was really clean and bright when we finished the work. We will be using it regularly.

I have had a Trex deck for 17 years. It was installed in 2000. It didn't get dirty for the first few years here in ON, Canada. Then it got mold and other stains. I tried many products, at the recommendation of the Trex Company. They contained sodium hypochlorite and oxalic acid. They temporarily only bleached out the mold. When the deck received moisture it came right back, costing me more time and money to again clean. Season after season it got worse, until it took over the deck. I then discovered Corte Clean at a retailer. I haven’t found anything that works as well, for as long, and proactively using it is the key. I just phone ordered 3 more bags. Proactively applying Corte Clean costs less money and time to keep my Trex deck clean.

I am 3/4 of a century old but got out on my veranda to give it a scrub with Composite Deck Cleaner, using the extensive directions provided. Honestly, I did not indulge in a heavy scrub, on my knees of course. Rinsed with the hose, let it dry and voila, magic, all the grease spots and others that would not be removed in the past are gone! I am more than pleased. My neighbours are begging for a bit to try. You may have more customers. Definitely 5 star plus satisfaction.

Thank you for the review. One shouldn't have to ever "heavy scrub, on my knees" ever when using Corte Clean, provided it is being used as per its label directions. Now, the trick is to keep your Veranda composite decking clean, which should generally cost you much less time, labor, and most importantly MONEY, when properly proactively used as our product was designed and intended. Generally, using Corte Clean, at the reduced strength, "at least twice yearly, spring & fall, or when stains appear" is proven to do this, especially in Washington, which gets so much routine moisture. Please let us know if you wish to thoroughly discuss. (415) 924-9500 X 1 P.S. You and your neighbors should order Corte Clean together, if you wish to generally save even more money.

We haven't heard from you? It is always best to Corte Clean composite decks of grease stains when the temperature is warmer, the grease has been allowed to solidify, the plastic composite has been allowed to expand and its pours open up, in direct sunlight, especially if Corte Clean hasn’t been proactively used as it was designed and intended "at least twice yearly, Spring & Fall, or when stains occur". The Corte Clean has to work from the top of the composite pour down, rather than from the bottom up. Corte Clean generally requires multiple applications to a thoroughly dry composite surface to remove grease stains when Corte Clean hasn’t been properly proactively used. Hopefully you didn’t skip the final Corte Clean label direction which states “When Corte Clean no longer becomes 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).” The best way to “Thoroughly rinse before using.” Is to allow natural moisture from rain to rinse. Generally, when this final step is done, and a composite deck has received moisture, stubborn grease stains or other difficult to remove stains disappear. Hopefully you followed this final label direction and the grease stains are now gone? This is generally the case. If they still exist, please consider trying this final label direction or proactively using Corte Clean and the stains will likely disappear. We can't help those that don't contact us, so please do if you have any further questions. (415) 924-9500 X 1

This is the best product out there to clean composite decks. It is hard work, but totally worth the effort. I paid a lot of money to have the deck built and I want to take care of it and ensure I have years to enjoy this beautiful deck. I have used it exactly as directed and no short cuts. It will keep your deck looking amazing! I just don't understand why it's not available in my local Lowe's anymore, so now I order it online. I've tried other stuff and it doesn't work as well or even at all.

Corte Clean shouldn’t be “hard work” if you are proactively using the product as it is designed and intended. All you should be doing is spraying it on, at “up to 2.5 scoops” to “1 gallon of water” strength, before your deck receives natural moisture, generally once in the Spring and once in the Fall, or when stains occur, such as after a BBQ, etc. This is why the Corte Clean label directions 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.” Letting natural moisture “thoroughly rinse” eliminates the one step of the “hard work”. Please review the Corte Clean website and call if you wish to thoroughly discuss, as this generally saves much time & money too. (415) 924-9500 X 1. Unfortunately, Lowe’s couldn’t properly inventory Corte Clean. Stores were always out of stock or product was left on the shelf beyond its “Best If Used By:” Date. This resulted in product failure for those customers that couldn’t read and follow this CRITICAL label direction, as Corte LLC does not provide a “Guarantee & Limited Warranty” for product beyond this date, as stated on the back & bottom of every Corte Clean 2000A bag. We now only sell to independent retailers and direct to customers like you online. Thanks for your business & 5 Star Review! Barbara, please call next time you need Corte Clean, reference this review & we will give you a discount.

My wife found your product on-line, She said it cleans those ugly black spots we have on our deck, I was skeptical and some of your reviews were not favorable and the price was high, I must say I was amazed how well it worked if the directions were followed exactly, especially the sunlight requirement, there is one area of my deck that was in shade, black spots in that area were not removed. I waited until later in the day when the area was sunlit and dry the second cleaning removed the spots. The best recommendation I can give is my second purchase. Thank You Paul K

Thank you for the 5-star review! Composites in shaded areas should be proactively Corte Cleaned more often than not or “least twice yearly, spring & fall, or when stains appear” as the Corte Clean label directions state. Those that follow this label directions should never have a mold problem. Composites in shaded areas don’t allow water to evaporate as fast, providing more water to the fungus, allowing it to root deeper, making it generally cost more time & money to thoroughly Corte Clean! It is extremely important to follow the Corte Clean label direction that states “•When Corte Clean no longer becomes 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 until thoroughly rinsed.” It is best to proactively apply Corte Clean before the composites receive natural moisture, so the moisture can “Thoroughly rinse.” Generally, difficult to remove stains come out after several days, if not immediately. If not, “repeat application process”. Please consider saving yourself time & money by proactively Corte Clean your Trex deck. Call us if you wish to thoroughly discuss. (415) 924-9500 X 1

My Trex deck is now 14 years old. I use Corte Clean every spring to pressure wash it and it looks like New. This is a great product . . . Best material for this application.

Thanks for the 5 Star Review! While we don't recommend Corte Clean be used with a pressure washer, nor does Trex for your generation (see Trex literature), your deck looks great! Generally, when Corte Clean is proactively used "Spring & Fall, or when stains occu" you shouldn't need a pressure washer. Please call us if you wish to thoroughly discuss, as we wish to help you generally spend less time and money on Corte Clean to keep your BEAUTIFUL Trex thoroughly clean.

Thanks for the FIVE STAR Review! The key to keeping your composites clean, especially of mold stains, but all other common stains too, is using it proactively. Proactively cleaning, at least twice yearly, spring & fall, or when stains appear, as most composite manufacturers recommend and Corte Clean was designed and intended will generally have you SAVING TIME & MONEY too. Please consider & let us know if you have any questions.

I love this product. I have a large deck that gets black spots on it. I spray Corte clean on, let it stand for a few minutes, brush the stubborn stains and rinse it off. I'm a 67 year old woman and am able to do it. It's easy.

Thank you for the 5 Star Review! Since you are proactively using Corte Clean, you shouldn't have to brush. To rinse, please consider applying before it rains or snows and allow the natural moisture to thoroughly rinse. While Corte Clean won't generally have that instant WOW effect in removing stains, generally, your deck will look clean a few days later. Please call if you wish to discuss, as we wish to save you even more time & money now that you are a loyal customer. (415) 924-9500 X 1

I installed a new composite deck in 2010. Materials used were Timber Tech and Trex products. The contractor recommended I use Corte-Clean do remove mold and midlew. I apply the product twice a year as recommended. The results have been quite good and I would not use any other deck cleaner. For me, the key to success has been to stay "ahead of the game" and not let the mold & mildew get a head start. I would recommend this product to anyone wanting to keep your composite material looking good through the years. D. Henderson (Ohio)

Thank you for the 5 Star Review! If only every composite deck owner read & followed Corte Clean label directions they would all generally save much TIME & MONEY, not just cleaning Mold & Mildew stains, but also Grease & oil, rust and tannins, flower pot, sunscreen, etc. and just about any other common stains. Unfortunately, most ignore product label directions and choose to waste time & money by reactively cleaning composites???

I live in northern Illinois and we are able to use our deck for approximately 5 months starting in May. I have been using Corte-Clean every spring for 5 years and this year I'm planning on a fall application so I can use a lower concentration next spring. I have been using a 3 scoop per gallon mix. I apply the Corte-Clean with a pump up sprayer and leave it on. The first spring rain after application removes the black mildew stains and even seems to bring the appearance of the decking material back to its original condition. I'm very pleased with the end results and ease of application of the Corte-Clean composite deck cleaner.

Our deck is under 2 large oak trees. The sap accumulates on the deck and when dry turns black. Until I bought your cleaner, I have been unable to remove the sap. It does take work but the results are worth it. I will upload before and after photos next time.

Thank you for the 5 STAR REVIEW! Please consider proactively using Corte Clean, especially under those "2 large oak trees", "at least twice yearly, spring & fall or when stains appear." Mix Corte Clean up, at up to the reduced strength on its label, spray on and let dry, as long as it is not turning dirty or discolored before it rains or snows. Stay off the deck until the Corte Clean is thoroughly naturally rinsed. This will generally SAVE you much "work", TIME & MONEY keeping your composites thoroughly clean, as Corte Clean will get under the sap stains in the pours of your composites and easily remove them from the bottom up rather than the top down when the deck receives moisture. Please call us if you wish to thoroughly discuss. (415) 924-9500 1
