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"!!!

“Great stuff especially for first generation composite decks. We put our deck in, in 2005 and we have tried every thing you can think off to clean it and this is the only thing we have found that really works. Be sure to follow directions and buy fresh product!”

“The pictures on the web site were impressive but I found them hard to believe. We live in the Northwest where it rains at least half of the year, and our deck is almost completely shaded by large trees, so moss and mold are a given. For two years I tried so many things to clean the moss and mold off of our deck, and none of them worked very well. I was always left with black spots. We don't know for how many years the deck was neglected before we bought our home, but as you can see from the photo, by spring it is really a mess. I bought Corte Clean out of sheer desperation and as a last resort before just replacing the deck. I added 4 scoops of Corte Clean to a gallon of water (nearly maximum strength), sprayed it on, and scrubbed the deck with a deck brush. After 20 minutes, I thoroughly rinsed it. When it dried, we were shocked to see how clean it got. It was a miracle! It was like getting a new deck. I never would have believed it if I hadn't done it myself. I can't recommend Corte Clean highly enough!”

“My composit deck was in terrible shape with stains from a wide variety of sources. I followed the recommended directions and what a wonderful surprise. An almost clean deck. After one application the years worth of stains have significantly deminished. I want to follow up with a second cleaning. I believe, from what I have already experienced, that my eight year old deck will look as new as the day I finished building it. I wish I had taken some before and after pictures. Oh well. What I am going to do is order two more bags. Then I will reorder in the fall. Great product! I am a satisfied customer.”

“Corte Clean is the only composite deck cleaner that I have found that will properly clean a composite deck. Multiple applications is required for tough stains, but it works.”

“Wonderful product. I have a 8 year old 16' x 22' composite deck. I had some black mold spots in an area that was shaded by the house. I first used an electric pressure washer very gently (not blasting it) so not to damage the composite. It helped, but the black mold spots quickly returned. I purchased 6 bags of Corte Clean. I only used 3 bags to do the job. This stuff really works. Very happy. The bags have an expiration date. I have not used the other 3 bags yet. I'll see what happens when I use it this year. Did the job 2 years ago.”

Thank you for the amazing review! Corte CLean does not have an "expiration date", but rather a "Best IF used By: date". Corte LLC only provides a "Guarantee & Limited Warranty" till this date. We don't suggest buying more than you will use in 3 to 6 months, from our website or right away from a retailer, as this date is 1 year from the manufacturer date. Corte Clean looses strength and will not likely remove difficult to remove stains, such as those caused by common Black Mold, Grease & Oil, Rust & Tannin, etc. If it has been "2 years" since you purchased it, it likely won't do the job and you will need new fresh Corte Clean. As you likely know, Corte CLean is designed to be used proactively, "At least twice yearly, Spring & Fall, or when stains appear" as its label directions state. Are you aware that most composite manufacturers recommend the same? Proactively using Corte Clean is this fashion will generally have you spending approximately 2/3rds less time and approximately 12/ the money or less. Failure to use Corte Clean allows mold roots to deeply root into composites and other stians to deeply saturate, costing more time and money to thoroughly clean due to the need to repeat the application process to a properly prepped thoroughly dry composite surface at maximum strength. Please consider saving yourself time and money, proactively clean your composites. Please let us know if you have any further questions. (415) 924-9500 X 1

“I have used this product since we got our composite deck over 10 year's ago. We live in the woods so we have a lot more debris on our surface. Corte clean does the job every year. I don't have to worry about any stains or mold . would recommend this to every one”

“Great product in that it goes beyond simple pressure washing to provide a uniform, unblemished look. A minor inconvenience is the need to cover the glass and rinse the siding below our deck to prevent white residue/spotting.”
