“We built our house with a new Trex deck in 1999 or 2000. It's the newest house on the street, as it's in an old neighborhood, where I owned the lot. It's in Wisconsin. We've got lots of trees around it. It gets mold, especially under the seats. I've tried numerous other products over the years. Nothing works as good as Corte Clean. I just ordered more.”

“I've heard recommendations of your product on the web and read reviews on your website but have not seen anything specific to my issue. I had a Trex Escapes deck installed about 7 years ago and overall it has been fine but over the past 3 years I've had a large silver maple tree grow over it and it seems to be dropping dirt combined with sap on our roof, gutters and trex deck. It appears simply as ground in dirt that I can't remove so I can only assume the tree sap is part of it. There is no obvious sap to be seen. I've had a power washer (electric, 1800) that has been able to clean it off (water only) over the years but it's gotten to be too much for it now to remove via pressure washing. I've tried to scrub w/vinegar but doesn't seem to do much. The first bag of Corte Clean did wonders with my deck so I just ordered more. It was amazing how it would break down the black mold so effectively!”

Most composite owners think Corte Clean is only for mold stains. Thanks for mentioning grease & the testimonial! Those that use multiple expensive laborious non-compatible cleaning chemicals, to clean specific stains, as commonly dangerously recommended by composite manufacturers & retailers can put themselves at risk of releasing toxic dangerous poisonous chemical fumes and/or be corrosive to structural metal decking hardware leading to early expensive replacement or collapse, when generally under load from people! This is the #1 SAFETY issue in the composite decking industry!!! You've earned a free bag of Corte Clean with your next order for adding pictures.

“This stuff is awesome! I use it to clean my TimberTech deck in NY. It was installed around 2010. My sister has a composite deck too. She was only power washing it and saw mine. She asked me how mine looked so new? I gave her a bag of Corte Clean. I just ordered more today.”

“My 12 year old composition deck was cleaned this spring with corte clean and it looks like new. Because I had power washed it previously it was a bit of a mess so I did clean it twice with corte clean.l NOW I will clean it spring and fall. I just stand back and admire it. Also, I had some questions about using the product and the company answered with great advice.”

Power washers are great for those that are extremely careful when prepping composites generally a week or more before using Corte Clean, to allow them to thoroughly dry out, to remove loose dirt & debris such as leaves pine needles, etc. Use of pressure washers alone, to remove fungi stains from common black & green colored molds, will generally exacerbate the problem, as you have unfortunately likely found, because they drive it deep into the pours & water it allowing it to deeply grow & root. This generally results in the need to repeat the Corte Clean application process, as you have found. We hope you admire your clean composite deck while spending less time & money. See how little Corte Clean you can proactively use to keep it clean. Thanks for the testimonial!

The people I spoke with recommended Corti Clean. It worked like a miracle ,deck was as clean as brand new.Spray it on ,let it sit ,clean with hose. I'm older and it was easy for me .Strangers still ask if my deck is new.”

“Our TimberTech deck is thirteen years old. Its color is beige and we chose to have the "grain" side up installation. We cleaned with Corte Clean in July only because where we live (Omaha, Nebraska) the weather is very unpredictable and, many times, the weather does not meet the requirements to use the product. Plus, it was just time to clean the surface of dirt and mold. Our deck is mostly in shade with our house and a tree blocking the assisting sun. The temperature at application was between 75 and 90 degrees, it took six hours to clean. Corte Clean worked wonderfully for us. I think at the higher temperatures we had, the necessity of sun is lessened. We used a maintenance level of cleaner (2.5 cups of cleaner) and, even though it had been two years since the last cleaning, it worked its magic. Using Corte Clean is rather labor intensive but well worth the effort. Thank you Corte Clean.”

TimberTech composite decking located "mostly in the shade" should definitely initially be cleaned between "65 to 85 F". This allows the composites to expand, pours to open, so the Corte Clean can deeply clean & remove the stains, especially those caused by molds! Depending on how many Square Feet your deck is, it can absolutely take "six hours to clean", especially if neglected for "two years since the last cleaning", allowing the stains to deeply saturate or root. It is highly recommended you proactively Corte Clean your TimberTech, as recommended in the TimberTech "Care & Cleaning" literature and on our product's label directions which states "at least twice yearly, spring & fall, or when stains occur" at the reduced "routine cleaning" strength to prevent deep stains. If you do this, it should generally only take you 45 minutes to an hour to apply & you should be using up to 1/2 the Corte Clean, or less, saving you MONEY. DON'T skip the final label direction that states "When Corte Clean no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces [ESPECIALLY IN SHADED AREAS]. Corte Clean is designed to continue to clean any time it receives moisture. A white residue may remain until thoroughly rinsed. Thoroughly rinse prior to using." The best way to "thoroughly rinse" is to apply before it rains & let the natural moisture do the labor. Please call if you wish to thoroughly discuss, as we wish to make sure your TimberTech remains clean for as long as possible with the least amount of cost, time & labor. Thanks for the testimonial!

“We installed a 62 1/2 foot Trex deck in 2016 in the mountains of Georgia. I worked for ACE hardware for 20 years. A friend of mine in Pennsylvania, that owns a ACE store recommended Corte Clean. Told us it was the only product to use. We used it last year and just ordered it again this year. This is a wonderful product.”

“Corte Clean is our go to deck cleaning product for our composite deck. There's no other cleaner we've found that can do such an amazing job! The process of cleaning is simple...we have a rather large deck and my husband and I can have the entire deck cleaned in an hour or so with the help of Corte Clean. I've even managed it by myself. We built the deck roughly 12 years ago and, after each Corte Clean cleaning, it looks brand new! Prior to finding the product, we looked into having the deck professionally power washed and it didn't come out that well and the price was hefty. Corte Clean leaves our deck looking new and for a very reasonable price. We are huge fans of this product and use like clockwork each and every year. Thanks Corte Clean!”

Thanks for the testimonial! Now that your deck is clean, please consider proactively using it "at least twice yearly, spring & fall, or when stains appear" at the reduced "routine cleaning strength". Those that do generally end up spending up to 2/3rds less time/labor & up to 1/2 the money because they are using up to 1/2 the Corte Clean. Don't skip the final 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 until thoroughly rinsed. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse composite prior to using." The best way to thoroughly rinse is to apply before it rains & allow the natural moisture to do the work.

“In 2011 we installed an AZEK composite deck in New Hampshire. Our son recommended Corte Clean when our deck started getting black and green mold in addition to other stains, as he too has a composite deck. Corte Clean does a really good job. We have been using it for years.”

“moved into new (for us) house three years ago and had done "NOTHING" to this deck so we decided to try Corte-Clean as it was listed as a good product to use. Once we got the hang of it was surprised how well it went on and did a "GREAT" job. Only used one of the two packets and have the other one ready for the FALL season.”

Now that you got your deck clean, you should be using up to 1/2 the Corte Clean, to keep it clean. Try to see how little you can proactively use. The less you use, the more you save. The remaining bag of Corte Clean should not only do the fall cleaning, but next springs cleaning too. Thanks for the testimonial on reviews.io.

“I purchased this product, based on recommendations. I had blackish spots on my light grey composite decking. I cleaned it throughly, but still had these darn spots. I searched for how to remove these spots, and saw a lot of recommendations of this product. I followed the directions for this cleaner, and could not believe the results. It’s foams up the dirt, and then you just rinse it away. Tougher spots need a little agitation with a soft brush, but that’s it. Attached you can see the cleaned boards and next to it, the spited boards I hadn’t cleaned yet. What a difference. I have already repurchased this product, in anticipation of cleaning my dock, since it is eco friendly, and plan to reclean everything in the fall. I highly recommend this product. It did exactly what everyone said it would do.”

Now that you are happy with Corte Clean, we wish to make sure you are spending less time, labor & money keeping your composite deck clean. Proactively using Corte Clean, as stated on it's label directions, "at least twice yearly, spring & fall, or when stains occur" at the reduced "routine cleaning" strength is the key, preferably before composites receive moisture and stains occur or deeply saturate. Don't skip the final label CRITICAL 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 until thoroughly rinsed. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse composite prior to using." The best way to "thoroughly rinse", is to apply before it rains so the rain does it naturally for you. Thanks for the testimonial!

“I have a Tendura composite decking covered porch, which was installed approximately 20 years ago, and is no longer manufactured. It's located in Virginia. Corte Clean is the only product that gets the mold stains out. I use to use chlorine bleach. It took two seasons of cleanings to get the impeded stains out the chlorine bleach caused. Additionally, don't use Soft Scrub, as it took several years to get the white out that this product caused. I've been using Corte Clean now for years. I use to buy it locally, but they stopped carrying it, so I now order online.”

We try to warn composite owners about the use of chlorine bleach or other sodium hypochlorite based products for cleaning mold! Unfortunately, most go down that path, exacerbating mold problems, often at the recommendation of manufacturers & retailers that ignore science in-order to promote & profit from The Chlorine Bleach scam . The longer one routinely uses this biocide, the deeper the mold roots, the more it excessively bleaches the color of composites beyond what most manufacturers disclose under "weathering", the more repeat applications it takes to thoroughly Corte Clean. Unfortunately, sodium hypochlorite can cause irreversible corrosion to structural metal decking hardware, the #1 SAFETY issue in the decking industry that is 100% preventable by not using it or other corrosive cleaning chemicals such as those that contain acids. Soft Scrub is a great product, but were not sure why any person would use it on a composite deck or for any purpose not stated on its label directions. Thanks for the review & call us for a discount on a future order.

“We did find 3 new bags at the Lehighton 84 lumber (I kept calling them because you had mentioned that they placed an order). What a difference fresh product makes!!!!! I figure if we have any left over we will use it in the Fall. I’m hoping if we do like April/September each year with one application, that it will do the trick to maintain the work we’ve done. Thanks again for the great customer support/service.”

The "Best If Used By:" date is critically important when cleaning deeply mold stained decking like yours. Once you get your composite deck thoroughly Corte Cleaned, proactively using it at the reduced "routine cleaning" strength is the key to generally spending less time, labor & money keeping it clean. Generally, this has the added benefit of composites staying clean for longer periods of time. Thanks for the testimonial! You've earned a discount on a future order, so just call.
