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 a trex deck in a new construction home with 2 dogs. The grass just got installed last year along with the deck. This year the deck was so muddy and dirty I thought it would never look like it did last year. I followed the instructions exactly as it was stated and the deck looks brand new. I cannot believe the difference. I did have to rinse it very well to get all of the white residue off. I wish I took a before picture. The results are amazing. I will continue to use the product year after year.”

“I have used Corte Clean on my Timbertech decking for many years. Great results! It is very easy to use. I live in the NC mountains where extremely high pollen count in spring, high humidity and cool mornings contribute to mold/mildew on my decking. Corte Clean makes my 14 year old porches look like new! I expect to use your product for as long as I live in my house!”

“this is our second year using Corte Clean to clean our composite deck. and it was much better this year. following the direction and using the maximum ounces per gallon our deck came out 90% better. We were very impressed with how clean it came out. We used a power washer to assist with the rinsing and it saved time. We will be doing it again in the fall since our deck is 14yrs. old. The instructions recommend cleaning the deck twice if it was in bad shape. Our needed some serious cleaning and now that we got it 90% we are shooting for 100% Thanks for making a good product to clean decks.”

“A long-time neighbor, who I'd never met before covid, mentioned to me that her husband was home washing their trex deck while we were out walking. I responded that we also had a trex deck, but a very old one. We got to talking about trex and how we maintain it: I've always used power washing and diluted bleach over the last 25 years. She told me that's exactly what the recommend I NOT do! So I asked what she used and she threw out a name I'd never heard of before. I tried to Google it when we got home but my search hit a dead end. Later that week I asked her to write down or take a picture of the product she uses for the deck. It was Corto-Clean. At first I thought it was expensive but I decided to buy 2 bags of the product to give it a try. If it didn't work, I was out $90 but if I liked it, I probably wouldn't need to use as much going forward. Well she stopped by while I was cleaning the lower deck and I was so thrilled with the transformation even after only one application. The second application the next day made the deck look almost new again! The other deck, which is now a porch, had a very old stain from where we used to have our grill. While it didn't remove the stain entirely, it made a huge difference. I'm confident that I can make it nearly disappear with future applications. Only a small amount remains of the 2 bags I bought. Rugs & furniture cover my problem areas but I definitely will be cleaning with Corto-Clean at least annually, if not again in the Fall. I'm so glad she recommended your product & I'm thrilled with the results. So is my husband! Respectfully Rose Weed”

YOU WIN FREE Corte Clean [not "Corto"]! Generally, as we state on the website, it takes several applications to remove stains from Trex, especially if it has been previously power washed and/or chlorine bleached with sodium hypochlorite based products. Your are correct, your "other deck" will become clean with future applications because the deeper stains are allowed to saturate or root, especially when they are power washed into the composites, the composites expand and contract with heat and cold, the grease and oil deeply saturate, especially if it is not allowed to solidify on a warmer day, the more applications are necessary to thoroughly remove. Ultimately, your Trex deck should end up costing less time, labor and money or Corte Clean to keep clean when routinely used because less and less is used, once your Trex deck has been deeply cleaned of the tannins from the exposed wood fibers and dirty recycled plastic from which it's made. Most find that Trex then begins staying clean for longer periods of time once thoroughly Corte Cleaned and when routinely used. Please contact us when you need your free Corte Clean.

“We have both Trex and TiberTech decking and I use Corte Clean at full strength to clean all of this material each year. It does an excellent of cleaning stains, mold and other stains on the decking material. It works best if you use a brush to scrub the deck after application and rinse when done. A good rain storm will remove any corte clean left after rinsing. I have used Corte Clean for 10 years and I am very pleased with it and the results.”

I love that when I call, if they don't answer, I know I will always get a call back. I just signed up for the yearly subscription.”

“We've been using Corte Clean every year for 13 years to clean our double Trex decks since they were new. It does what we need it to do in moist Virginia. It's a great product! We've never used anything else and our Trex looks almost new when cleaned. We learned of Corte Clean from our contractor and/or in the Trex literature. We use to buy Corte Clean at Lowe's but they stopped carrying it and we have been buying it direct online from its website ever since.”

“I wish I could remember how I found out about Cort Composite Deck Cleaner, so I can thank them for tell me about such a fantastic product. We have a light grey composite deck, which gets dirty and develops small dark spots. This is the only product that has worked, making the deck look like the day it was installed. The photo shows the difference this cleaner makes!”

“I called TimberTech and they recommended Corte Clean when their other recommended product failed in cleaning the green from my deck. The other product was an expensive hassle, as I was having to clean my deck 3 times per year. The green just kept coming immediately back! Corte Clean keeps the deck clean on my condo in Ohio for nearly a year. It looks brand new after I use it. I have now been using it for 6 or 7 years. I just ordered more for the spring cleaning.”

“I have used Corte Clean for over 10 years and have found it to be the best solution to cleaning my composite deck. most of my deck is grey so it is difficult to detect any weathering. I clean it every Spring. I know I should clean it again in the Fall, but I'm too lazy (and cheap)! It would make the Spring cleaning easier. All things considered, I am very happy with this product.”

Thanks for the testimonial! Don't be so "cheap"! It's likely costing you more time, labor & money/Corte Clean by skipping applying in the fall; as most composite manufacturer's recommend & our product was designed to be used. Proactively using Corte Clean at the "routine cleaning" reduced strength (up to 1/2 strength) will generally result in savings, especially if you apply before the composites get deep stains. This has been proven for we'll over a decade.

The more routinely Corte Clean is generally initially used, less & less is generally needed, the longer composites are generally known to stay Corte Cleaned; sometimes for years. It is critically important to get composites thoroughly cleaned of the tannin bleeding issue which with exposed wood fibers and/or dirty recycled plastic can feed fungi! Failure to thoroughly Corte Clean composites of all stains is generally a waste of time, labor & money/Corte Clean. Thanks for the testimonial!

“I tried everything to clean my composite deck, including power washing and various cleaners. I just could not get some of the stains out, including grease (from grill) and mold. I purchased the cleaner and long-handled brush. Using it was able to get most stains out. I have done this for the past two Springs and will do it again next year.”

Thanks for the testimonial! If all the stains didn't come out on the first application, "repeat" the application process at "maximum strength" and DO NOT skip the final label directions 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 anytime it receives moisture. A white residue may remain until thoroughly rinsed(use a brush if necessary). Thoroughly rinse composite prior to using." The best way to thoroughly rinse is to apply before it rains or snows. If your deep stains don't come out, they generally come out over time with routine "Spring &Fall" proactive cleanings over time with problematic composite decks. Please call if you wish to thoroughly discuss. Happy Holidays!
