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"!!!

I have used this product for many, many years and it does a great job. If you have well water you should mix it with bottled water for best dissolving results

Thanks for the 5 STAR review! Corte Clean was designed to be used with pure water. If you have hard water, you can use bottled water or LESS Corte Clean per gallon of water (4 scoops insted of 5). To increase the strength, you can then sprinkle Corte Clean powder on the area already wet with Corte Clean and brush. Additionally this can save money in areas with stubborn stains.

Thanks for the FIVE STAR review! Please consider using Corte Clean proactively, "Spring & Fall or when stains occur". This generally saves YOU much time & money, especially when used before the deck receives moisture and stains occur, deeply root or saturate. Please see the website or call us if you wish to discuss.

This stuff is great. (Can I end it here?) My composite deck looked awful with black mildew over about a third of it that lies under tree branches. I used it as directed last fall (it took a little more than "light" scrubbing), and it looks 100% better. I plan to use it again probably in March or April, and after that, I see easy maintenance with Corte-Clean from now on. I've uploaded a photo, but it's rotated 90 degrees, for some reason.

My composite deck had not ben cleaned with a chemical cleaner since it was installed more than five years ago. I had used soap and water to remove the pollen over the years, but the mold was virtually unbeatable. I used Corteclean as directed and in one application the results were excellent. The mold has disappeared from 95% of the decking. I have a couple small areas that I will clean again and expect that all evidence of the mold will be removed. When I cleaned the deck, half of the deck space was in bright sunlight and half in the shade. It appears that the cleaner was most effective where direct sunlight was reaching the deck.

Product was very effective in cleaning the composite deck. The deck had not been cleaned thoroughly since it's installation 5 years ago and there was significant buildup. The product effectively cleaned the surface.

Thank you for the 5 STAR Review! To generally save yourself much TIME & MONEY, please consider proactively using Corte Clean “at least twice yearly, spring & fall, or when stains appear” as its label directions state. Corte Clean was designed and intended to be used in this fashion, as most composite manufacturers too recommend. Hopefully you followed the final instruction on the Corte Clean label directions, which are designed to ensure your composites are thoroughly clean and stay clean for longer, and state “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. Thoroughly rinse composite prior to using.” The best way to “thoroughly rinse” is to apply before the composites receive moisture from rain or snow and let it naturally rinse saving time and water. The reduced Corte Clean strength of “up to 2.5 scoops for routine cleaning” per “1 gallon of water” is for proactively Corte Cleaning and will generally have you saving money because you are using up to ½ the Corte Clean. Whatever you do, please don’t let stains deeply saturate into your deck for “5 years” and “significant buildup” to occur unless you wish to waste a bunch of time and money keeping your “composite deck” clean, especially in San Francisco, CA where the fog and morning dew can exacerbating cleaning issues. Please let us know if you have any further questions. (415) 924-9500 X 1

Works great for cleaning common mold and barbecue grease or oil from Trex in one product. Once you proactively use it, for a few seasons, your deck starts staying clean for longer and self washes when it rains. The key is to apply, at the reduced strength, before it rains and let the moisture rinse it. You end up spending a whole lot less time and money purchasing and using Corte Clean.

My Trex deck had become a daily gathering place for up to 15 Peacocks so you can imagine how much dried up mess they had made. I had previously tried to clean it with a hose and stiff brush without much result then I discovered Corte Clean and it was gone with just the one application, I am very impressed with your product and will continue to use it on my deck.

I never heard of Composite Deck Cleaner until a deck builder told me about it. It is fabulous. It gets rid of all kinds of dirt from Bird droppings to mold and concrete stains. Easy to use.

Thank you for the 5 STAR Review! Our small one product family run American made business greatly appreciates it. Now that you have found Corte Clean "Easy to use", hopefully you will choose to spend less time & money keeping your composites clean. Proactively Corte Cleaning, Spring & Fall, at the reduced Corte Clean strength is generally the key to doing this. THank's to your contractor too for recommending our product.

Can't rate it yet because I haven't received it yet. Ordered 9/24, reported to be Shipped 9/26. Received at Fed Ex Sacramento 10/5, Shipped from there 10/6. With these delays in shipping and still not sure when I'll receive this product, I'll be reluctant to purchase it again.

Sorry for the delay. Corte Clean became back ordered due to so many routine customers purchasing and doing the recommended FALL cleaning. The factory did not inform us of the delay. Good news is that your Corte Clean will be the freshest product available. The fresher it is, the better it works.

I have tried everything I knew of to clean my parents deck. They had Timberteck decking installed. The deck is mostly in shade and surrounded by trees. I would have to pressure wash it every year due to the sap, leaves, and debris from the trees. After a few years, I found a few areas where it just would not come clean like it used to. Found out that these area retained water for longer periods of time and became moldy. I tried soap, lemon juice, baking soda, and mild detergents. Nothing seemed to help. I searched online for other possible solutions and found Corte Clean Composite Deck Cleaner. I decided to order and give it a shot. All I can say is - WOW!! The areas are clear and the deck looks like its new again. I filled the sprayer with the solution and sprayed the deck. Following the instructions of keeping the area wet and giving it time. I did use a medium/soft bristle brush to lightly scrub the bad areas. The results are amazing. Thank you Corte Clean. I have already recommended the Composite Deck Cleaner to friends and family that have composite decking and they have had similar results.

We thought our deck was lost to black mold spots. We had tried several cleaners available in hardware stores to no avail. Our contractor encouraged us to order the Corte-Clean because we had used it 3 years earlier and was happy with the results at that time. It worked great on getting off the black mold spots and unlike with all those other cleaners the spots have not returned. Our contractor was so impressed with this product that he kept the empty bag so he can recommend it to future customers. We'll never waste time and money on any other cleaner. Thank you Corte-Clean!

Thank you for the 5 Star Corte Clean Review and taking the time to write a testimonial! Most of those “cleaners” purchased from “hardware stores” contain sodium hypochlorite, the active biocide in chlorine bleach, which is not scientifically proven effective for cleaning “black mold” by an Oregon State University scientific study. However, sodium hypochlorite is highly effective at corroding out the structural metal decking hardware! This generally leads to expensive replacement or failure. The is the #1 issue currently facing composite deck owners. Many Corte Clean customers have done exactly what you have done, used Corte Clean then tried other products for whatever reason. They always come back for the same reason… RESULTS! With proactive routine use, at least twice yearly, Spring & Fall, generally composite owners notice the “spots have not returned” and never should. Proactively Corte Cleaning composites, before composites receive moisture and “black mold spots” appear is the key to generally spending up to half the money and generally 2/3rds less time. This is because, as the Corte Cleans label directions state, “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.” The best way to “Thoroughly rinse composite prior to using” is to apply before it rains or snows. This can be done in any condition, day or night, as direct sunlight and temperature don’t matter. While this generally won’t have that instant WOW effect of immediately removing stains, generally they will disappear. Climates that receive routine moisture should be proactively cleaned more often. Example: Winter, Spring, Summer & Fall. Should one have parties, track, spill or drip oil & grease, or notice rust, this should be immediately cleaned. Please consider saving yourself time and money by proactively routinely using Corte Clean at the reduced strength, especially when the stains are first noticed. Please let us know if you have any further questions and let your contractor know of our program for recommending our proven product and tell him to call us. (415) 924-9502 P.S

This product isn't just good - it is SUPERB!!! I told the CorteClean customer rep that I purchased their product because it was one cleaner listed in the TimberTech maintenance instructions. I had used the cleaner twice - each time scrubbing the deck using a stiff bristle brush. However, within a couple of months I could see some black mildew spots. The CorteClean rep recommended I should be lazy - put a couple of scoops of CorteClean in a gallon of water, spray the deck liberally, then sit down and have a beer and let the deck dry....the next rain will activate it. So I followed his recommendation....2 days later it rained....and 2 months later the deck still looks spotless and brand new!! The hardest I worked was to pump the sprayer....and open a beer. You cannot go wrong with this product!!!

The best Corte Clean review ever! We are always happy to hear when we save our customers time & money keeping composites clean. If only every customer understood it really is this easy to keep composites clean, when Corte Clean is proactively used, as it was designed and intended. Hopefully, because of your review, more customers will choose to enjoy beverages on composite decks and less time and money keeping them clean.
