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 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've used corte for close to twenty years on my composite deck. I purchased you product from Lampert's where I bought the deck lumber. I bought it there a few years ago and it didn't work very well. a friend told me it was probability old. I didn't know it should of had an expiration date. I ordered it directly for your company and it worked fine.”

Thanks for being a long time customer. Unfortunately, many retailers don't properly manage their inventories on a first in/out basis. This has been a major problem in the paint & sundries category, which includes deck cleaners, not just at independent retailers, but the home improvement warehouses too. Like many products, chemicals don't last forever. They degrade over time. Cleaners don't clean as well, as they degrade and loose strength. Many products have a code, like a can of tuna fish, that alert customers at point of purchase. Well run retailers will put these items on sale in order to move them months before they go beyond the date and not sell products beyond a manufacturer date for all the obvious reasons. Corte Clean has a very noticeable "Best If Used By:" date on the lower right hand back of every bag. Corte does not provide a guarantee or limited warranty, as clearly stated on the bottom of every bag, beyond this date because we know it will likely fail. Just like you wouldn't want to eat out of date rotten tuna fish, you don't want to waste your time with out of date chemicals. Thanks for the testimonial. Please call next time you need to purchase Corte Clean so we can give you a discount for taking the time to write this testimonial.

“We are longtime fans and users of corteclean. Our deck is Weatherbest board and fiberon rails and it looks fantastic The deck frame is pressure treated wood, which has moss/ mold stains. Can we use it on that? In places where Corteclean drips through, the wood is clean. While we are again doing the deck, we would just like to clean the whole structure ….”

Thanks for the testimonial! You pretty much answered your question. It's always a good idea to re-apply the treatment used to protect treated wood once cleaned, if you want it to last as long as the decking. It's always best to contact the manufacturer of the treated wood to find out what they recommend. An examples of products are manufactured by Green Products, C0. Their Green Wood Preservatives such as Copper-Green comes in the colors of green, brown & water based clear.

Thanks for the testimonial! If you have previously used chlorine bleach or any sodium hypochlorite based product, especially in an attempt to remediate (routinely clean) mold, and exacerbated the problem in addition to causing corrosion stains around structural metal decking hardware (black or red stains), and not cleaning other common stains from grease & oil which this biocide does not generally remove, it can definitely take more time, labor and Corte Clean to INITIALLY thoroughly clean most composites. Once thoroughly Corte Cleaned, it should generally takes approximately one (1) hour to keep the average 300 Sq. Ft. composite deck clean, of all common stains, not just those caused by molds, when properly proactively used by following the Corte Clean label directions. This has the added benefit of using UP TO half (1/2) the Corte Clean at the "routine cleaning" strength, so you'll be spending up to 1/2 the money and you will not dangerously corroding your structural metal decking hardware. Those that properly proactively use Corte Clean generally find their composites staying clean for longer & longer while using less & less. Please call if you wish to thoroughly discuss.

“We have a Mendards UltraDeck in Illinois that was originally brown but the sun faded grey. Corte Clean cleans all the stains from it. You name it, it cleans it. It is the only product that works. I use it once per year. I have been using it every spring for years. I love the product. I originally found it on Amazon.com but now buy it directly from the website.”

Thank you for your order today, being a long time customer & your testimonial. We have given you $10 off your order today to show our appreciation. Corte LLC has NEVER SOLD CORTE CLEAN or authorized any vendor to sell Corte Clean on Amazon. Amazon has allowed the sale of counterfeit and/or Corte Clean that is beyond it's "Best If Used By" date which generally will fail to be sold on their website. Corte does not provide a Guarantee or Limited Warranty for counterfit Corte Clean or Corte Clean that's is beyond it's "Best If Used By" date. This has resulted in dissatisfied customers. Do not purchase Corte Clean from Amazon or any retailer where Corte LLC is not the vendor, any retailer not on the Corte Clean store locator or product that's beyond its "Best If Used By" date. You too will likely be dissatisfied!

“Every time I use Corte Clean on my Timber Tech Deck, I feel like my deck is brand new! It's so effective and easy to use. I also appreciate the awesome customer service. A couple years ago I called and spoke with a super helpful associate who tipped me off to ways to keep my deck in good shape all year long, even though it's exposed to some winter weather in Pennsylvania. Late last fall, I purchased some composite deck furniture and this spring Corte Clean made those look fabulous as well. I'm a faithful customer and tell anyone I know who has a composite deck about Corte Clean.”

Thanks for the testimonial. We do not currently sell Corte Clean in Canada retailers. Generally, across the US/Canada boarder a short drive from you, 84 Lumber Tonawanda, NY stocks Corte Clean. (760) 695-3784. Unfortunately, currently the US/Canada boarder is closed due to Covid-19. Hopefully it opens in the coming days or weeks. Additionally, we can ship Corte Clean to a forwarding company address in the US that pays Canadian taxes and delivers to Canadian addresses via phone order. Sorry for the inconvenience.

“I have a light grey composite deck that had dark stains on it. I tried power washing and other cleaners and thought I would have to live with a stained deck. I saw Corte Clean on a forum and thought, why not. I made the leap and purchased this and was completely amazed as it is as good as people said it was. All the stains on our deck are gone and it looks brand new.”

There's good reason the Corte Clean label directions state what they do. Those that carefully read, comprehend & follow them generally spend less time, labor & Corte Clean (MONEY) initially cleaning & keeping them clean. Unfortunately, those that are unhappy with our proven product fail to do this or initially order enough to thoroughly clean expensive composites, especially if they have neglected or previously used sodium hypochlorite for mold. We've given you an additional discount on your most recent order. Thanks for your testimonial & order. a few seconds ago

“This is the best cleaner for our deck, work's GREAT and last all summer for us.”
Helpful Report
Posted 3 years ago
The reason Corte Clean "lasts all summer" for you is because once porous composites are thoroughly cleaned of the tannin's, from the wood or other organic materials from which they are partially made, and/or dirty recycled plastic, which can feed molds, in addition to other common stains stains, the Corte Clean soaks in. This is why the label directions state "Corte Clean is designed to continue to clean any time it receives moisture. A white residue MAY remain until thoroughly rinsed." If the "white residue" isn't visible, but oxygen bubbles are noticed when the composite "receives moisture", Corte Clean will "continue to clean" anything that lands on the composites, such as mold stains, grease & oil, rust & tannin's, etc., lifting stains from the bottom of the pours up, not top down, which takes more time & costs more Corte Clean. In summery, the longer Corte Clean remains, the longer it can remove difficult deep stains and/or the longer composites remain clean. However, we always recommend that composite owners always "Thoroughly rinse composites prior to using." Once the owner is done using the composites, it's a great idea to re-apply at the "diluted" "routine cleaning" strength "at least twice yearly, spring & fall, or when stains appear", preferably before the composites receive moisture, especially if mold stains are the primary cleaning issue. Those that do this correctly, more often than not, especially when initially using Corte Clean with composites that are notorious for mold, generally find that they use less & less Corte Clean to keep composites clean while they generally stay clean for longer & longer. Some owners have reported their composites have remained clean for years, however this is unusual, especially if composites receive frequent routine moisture. Thanks for the testimonial.

“I have a 16 year old Trex deck on the north side of my house in Wisconsin. About 10 years ago, it began getting black and green mold on it. One of my neighbors recommended Corte Clean, after she tried countless other products on her deck, then her builder recommended it to her. She gave it to me to try. I'm very happy with the product and just ordered more. It works good.”

I discovered this on the internet when I was looking for a miracle cleaner and to my surprise this was my miracle cleaner. I was so impressed the first time I tried it! My deck is a light color so it starting showing mold stain within a year or so. Corte Clean removed the stain. Highly recommend to everyone!”

Thanks for the testimonial! We've given you FREE SHIPPING on your order today. If you generally wish to save more TIME & MONEY, please consider using Corte Clean as its label directions state, "at least twice yearly, spring & fall, or when stains occur" at the reduced "routine cleaning" strength of "Up to 2.5 scoops" per "gallon of water". Try to see how little Corte Clean powder can be used to keep the composites clean (1 scoop up to 2.5???, as it depends on what wood & plastic the composite is made from) "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 prior to using." The longer the Corte Clean remains on composites, the deeper it soaks into the pours of most composites, the longer they generally stay clean. The best way to "thoroughly rinse" is to apply before it rains or snows. Let the natural moisture do the work. Always make sure the composites are thoroughly rinsed prior to using by children, people, pets or anything living. Generally applying prior to putting the patio furniture out in the spring, and when it's put away in the fall is all that's necessary, however, composites located in moist areas or where dirt/derbies/etc. can need additional applications to keep clean.
