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 have been using Corte Clean twice a year for the last 4 years and have found that Corte Clean works the best of all the products on the market. We have a trex front and back deck. We follow the instructions and it works great. I would recommend Corte Clean to anyone. Here in Indiana the mold get bad and Corte Clean use twice yearly does WORK”

We love hearing from customers that have used other products! The label direction that states "Use Corte Clean at least twice yearly, spring & Fall, or when stains appear" at the "routine cleaning" strength generally prevents deep stains while costing less time, labor and money to keep clean. Thanks for the testimonial! Please let us know next time you need Corte Clean. We'll give you a discount.

“I have tried other products, after trying Corte Clean, to clean my 10 year old TimberTech deck. I did this because Lowe's no longer carried it, so I tried what they and others had. Don't waste your time. In NJ, these decks get dirty, especially in the shade. I find a lite brushing in these areas helps remove the mold faster. I find that purchasing it directly from the company I get the freshest product and it works better/faster. I just purchased more today. I love your product!”

Thanks for the testimonial & order today! We discounted your order by an additional $10 to show our appreciation. Our small, 1 product family run business can't thank retailers enough for all the customers, that once bought Corte Clean at their local store(s) & now buy direct, from our website, especially this year with Coronavirus. It's always great to hear of the inferior products retailers replace Corte Clean with. It's unfortunate that so many composite owners waste time and money purchasing and using these products.

“This is the first time in 15 years, I used Corte-Clean to clean my deck. It literally cleaned up all the gunk(bird dropping, algae, oil etc). The Trex flooring looks completely new, shiny and brand new. Happy with the product will use it every year.”

Thanks for the testimonial. You've earned a discount on your next order. Please contact us when you need more. Please consider following the label direction that states "Use Corte Clean at least twice yearly, spring & fall, or when stains appear" at the reduced "routine cleaning" strength if you wish to generally spend less time, labor & money keeping Trex deck Corte Cleaned. Hopefully you didn't skip the final label direction, especially with your 15 year old neglected Trex deck, 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). Thoroughly rinse composite prior to using. This generally deep cleans neglected composites and prevents future deep stains while preventing new ones. Try to see how little you can mix to a gallon of water to keep your composites clean. Apply before it rains to allow the natural moisture to thoroughly rinse.

“We use to buy Corte Clean at Lowe's, till they stopped carrying it. We now buy it direct, from the website. We have been using it for at least 10 years to keep our 20 year old Timbertech deck clean, especially of the mold. We've tried other products and wouldn't think of using anything else again.”

We have had a lot of customers that use to get Corte Clean at a local retailer, but now buy it online, direct from us. Most retailers aren't loyal to a specific product or brand. They are more interested in the margin they make & perceived low price points. Most buyers for retailers don't understand the problem of cleaning & keeping composites clean, as they don't own a composite deck, and believe claims of "NO MAINTENANCE". They choose to sell "The Chlorine Bleach Scam" by selling deck cleaners that contain sodium hypochlorite to clean mold. Only those that have properly used Corte Clean to thoroughly clean composites, then try something else, especially to clean mold stains, can understand this, especially when the molds rapidly return. Thanks for the testimonial and order today. We gave you FREE SHIPPING ($6.99 OFF), plus an additional $2 off, for a total of $8.99 to show our appreciation of your testimonial, loyalty & order today.

“I have been using Corte Clean Composite Deck Cleaner for at least 5 years on my Trex Brasilia deck. Prior to using Corte Clean, I used to use a mixture of bleach and water combined with a cleaning solution that was once recommended by Trex, as well as, using a pressure washer from a distance. I wish I had found Corte Clean much sooner, because the other solution really took the color out of the decking and the power washer probably contributed also. The first time I used Corte Clean, it was a noticeable difference, as the black spots, green mold, leaf residue and grease stains near the grill were taken away by simply applying with a pump sprayer and then lightly scrubbing the deck surface with a brush. To achieve excellent results, you must follow the instructions, which are not difficult, but require patience. Also, the weather conditions, such as temperature and sunlight, should be favorable for this product to really clean well. I use this product each year to clean thoroughly in the Spring and then lightly in the early fall. What I love most about it, is that it seems to leave an invisible residue on the decking that activates in the following weeks after cleaning whenever it rains, which keeps the mold spores from returning.”

“We've had our large Timbertech deck on the back of our house for 14 years. It gets moldy in Ohio. I clean it every year, when I can see it coming back. Corte Clean works pretty darn well. I have a half a bag left over from last year and just ordered another.”

Thanks for the testimonial! Please consider using Corte Clean "at least twice yearly" at the reduced "routine cleaning" strength, preferably before it rains & stains appear. "Spring and Fall", before you put out the patio furniture for the summer, and when you put it away for the winter, is best. This should save you time & money. To show our appreciation, we have not charged you for shipping on your order today.

“This will be our 3rd year of using Corte Clean to clean our composite deck. It gets easier and quicker to clean each time.”

Once the underlying flaw of "tannin bleeding" and dirty recycled plastic from which most composites are made, which literally can feed the root of the problem, has been thoroughly cleaned, most end up using up to half or less Corte Clean to keep composites clean with "routine cleaning". This saves money while having the added benefit of being more eco responsible because less is used. Thanks for the testimonial.

“I've used Corte Clean to clean my Trex deck for about 10 years. I live in central NJ and without treatment my deck develops green and black mold spots. I tried a different product one year and was very disappointed. I use Corte Clean proactively twice a year as recommended and it is fast and easy to keep my deck looking like new. Additionally, customer service is very helpful with suggestions and instructions.”

“I've had ChoiceDek in for well over a decade in Tennessee. I use to use Clorox for the mold, until it really did a number on the plastic. The plastic railing became rough and the deck turned solid black. It no longer worked for the mold. I then tried Corte Clean. It worked perfectly. I have been using it for years, spring and fall. I just purchased more today.”

Thanks for the testimonial. We have discounted your order by $10 to show our appreciation. The recommendation and use of chlorine bleach or other sodium hypochlorite biocide based cleaning products, to clean mold, has been the problem in the composite decking industry for all the reasons we point out on the website. Unfortunately, most don't find out till they have used it, as unfortunately has happened to you.

“We have been using Corte Clean on our deck for a few years now and don’t consider using anything else. We have a Trex deck that was built about eight years ago and in areas that don’t get enough air flow underneath, we get spots of dark mold. The Corte Clean makes such an amazing difference! We clean it in the springtime and along with spraying and waiting the suggested time, we also keep a stiff bristle broom and give the section a little scrub and rinse. It’s an easy process and once it’s done, the deck feels so clean and feels good on bare feet. We really enjoy our deck after it’s cleaned.”

“We have a Trex deck located in Minnesota that is approximately 10 years old. We bought it because it didn't need to be painted so it would last. After about a year, it started getting black mold spots all over it. We went online and found out Trex was known for this problem. Had I known Trex had this problem, we would have rather installed a wood deck and just painted it. We contacted the Trex company and they were not helpful. We went to Lowe's and discovered Corte Clean. Unfortunately, it was beyond its expiration date, and didn't work! I called the Corte Clean company on a Saturday and they resolved the problem. Corte Clean is the only stuff that got the deck clean. Lowe's no longer carries it, so we order it from the company. We have now been using Corte Clean for 10 years.”

“I found out about Corte Clean from my father-in-law, who use to own a house with a composite deck. We use to order it together. I have a 12 X 14 second story Timbertech deck with stairs down to the ground level in New Jersey. It has lots of trees around it and gets mold. I take the pressure washer to it to remove them, then use Corte Clean. I do this twice yearly, in the spring and fall. I have been using Corte Clean for 10 years. The deck still looks brand new, excluding where it wasn't properly installed with proper drainage gaps.”

“We get black mold spots on our composite deck. I have two types of composite decking, as we extended the deck. It's about 400 square feet total in Iowa. This is my 4th time purchasing Corte Clean. I tried some old Corte Clean and it didn't work. I noticed the date was expired from 2018. Fresh Corte Clean works pretty darn good! I just bought two more today.”

“My husband and I installed a TimberTech composite deck to replace the old rotted out wood deck on our condo in Ohio. We didn't want to have to sand, paint and seal anymore. We were looking for less maintenance. To our surprise, mold showed up, so we bought a pressure washer to clean it. Using it was a lot of effort and didn't get the deck clean! Additionally, we were worried about permanently damaging the expensive decking, as so many of our neighbors have done. Most are now black with mold. Their decks look awful and they cover them with rugs. I called TimberTech and they recommended Corte Clean. I am very happy with the product. We have now been using it for 3 or 4 years. It works so well, I sold the power washer because I no longer need it. I am very happy with the product and the way it cleans.”

“We have an expensive large Fiberon Horizon PVC coated deck we installed approximately a decade ago here in Kentucky. It's actually 3 decks, on 3 levels, with stairs handrails, balusters, etc., around 400 square feet total. It is the textured decking that looks like wood with deep grooves that traps dirt and derbies. It gets real dirty and difficult to clean. I tried another product, but it excessively bleached and permanently damaged the deck! I can still see where I used it today, which makes me mad. I called the manufacturer, Fiberon, and they recommended Corte Clean. It is awesome! It is easy to use. You can see it work. We have been using it ever year since we found out about it. I use to buy it locally but now buy it directly form the website. I don't mind this, as it is fresher & works better. As long as we own this deck, and live in this house, we will be using Corte Clean to keep our deck clean. God bless you.”
