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"!!!

“Our Trex deck was so bad, we hired a professional to clean it as whatever we tried didn't work. The person that came out to do the job used CorteClean and it turned out to be an unbelievable transformation. He told us how to order it and to keep our deck looking this good recommended that we do it twice a year but at half strength. This has worked very well and it is an amazing product. We discovered it quite by accident and I do fault Trex for not making their customers aware of the fault of this composite deck. Apparently the Trex decks are made differently today but as ours has been here for about 15 years or so, we had to make do with what was here. We would highly recommend CorteClean and also would encourage users to keep up with the maintenance. This makes it much easier. Also the customer service is outstanding. We were given advice on how to make the job easier and have been very satisfied. Palatine, IL.”

“Just follow the directions and wear rubber gloves. This cleaner works very well. Our weather in Western Pennsylvania has plenty of rain which, causes algae-the green color that appears on composite decking material. The Corte Clean removes the algae with a little scrubbing involved. It's best to clean your deck several times each year with this cleaner.”

“I have used this product for years and have found that it is the only product on the market that returns my composite deck to its original state. No mold, no stains. I have found that a "lite" treatment in the fall will save a lot of scrubbing during the spring treatment.”

“This cleaner was easy to use, we sprayed it on and let it sit then scrubbed lightly with a long handle brush. The deck came out like new. We used it on a year and a half old deck, grey Trex reliaboard. Its a great product!”

“The product is easy to use and works effectively. The brown color indicates that the product is working and after light scrubbing a simple rinse is all that is needed. Power washing with other products can't remove those black spots like Corte Clean. Very satisfied.”

“Exceeded my expectations!!! After 4 years the TimberTech decking became quite stained with mildew residue spots created by rain. I power washed it a year ago however it did not remove the deep stains. Two weeks ago I used the Corte*Clean, following the instructions carefully! It really worked - the stains are gone and the deck looks nearly as it did when first installed!!! Note that after applying the Corte*Clean solution on the deck, letting it absorb for 10-20 minutes, scrubbing it with a brush, I power washed the deck, instead of just rinsing with a hose. The hose rinsing alone left some stain residue (though much less than after just power washing, but still noticeable) - so my recommendation is to power wash to rinse!!! One happy customer ...”

“The product worked very well as advertised. It cleaned my TimberTek deck using a power washer as well as the PVC rails. I would recommend it.”

“Joe from uniontown Pa. I have used corte clean ever since I had a timber tec deck installed eight years ago. This is the only product that really cleans my deck. A composite deck is not maintenance free. It does grow mold and mildew and corte clean is the product that gets it out. I give it a 10. Would recommend it to all.”

“I live in the extremely rainy, mossy and mildew growing Northwest. Over the years, I've tried many products formulated for decks, but none made much of an improvement in the appearance. However, after an application and good cleaning of our Trex deck, Corte Clean produced was the best result I've ever obtained. Some visual permanent staining from years of inadequate cleaning are still seen, but very inconspicuous. And cleaning the second spring was much, much easier.”

“Have a 3 year old Trex "Enhance" deck about 15% of which was markedly affected by animals and leaves from the tree canopy overhead. The remainder of the deck, though no where near as bad, was still in need of a cleaning this spring. Purchased Corte Cleaner based on the reviews and followed directions on package and your website. Was amazed at how quickly the deck was cleaned. Your product performed as advertised. I have ordered enough for the rest of this year and next. I will not even look at a substitute. Apply at the stronger concentration and rinse the area repeatedly to avoid any residue. A good pump sprayer, long-handled brush (together with any other brushes to get in odd nooks) and pressure washer are all the major tools you will need. Both the lightly and more heavily stained areas now look alike. My neighbor even commented on how much the deck now appears brand new! Couldn't ask for an easier project. About 3 hours for a 1000 sq ft deck.”

“Deck was really dirty and full of black spots . Corta Clean spiffed it up and looks so much better. We should have gotten to it last year but better late than never. We used Corta Clean a few years back as we purchased it from Costco. Now, the only way we can purchase it is directly on line. The product works and so we will order it again . Great product .”
