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.

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 previously was using another chemical product that did a very good job. They seemingly are out of business. I tried Corte-Clean and it is a comparable product at 1/2 the cost. I used it on my composite decking with a chemical sprayer, deck scrub brush and garden hose. Easy to use and cleaned my deck as I hoped it would. Will be ordering again in 6 months!”

Thanks for the testimonial. When you again use Corte Clean in 6 months, hopefully you are using 1/2 or less, so you will again cut the cost of keeping your composite deck clean, then, you'll be saving 3/4 the amount you use to spend. Now think about how much you'd have been saving if you had been using Corte Clean since your composites were installed?

Those that properly use Corte Clean, by following its label directions & purchasing enough to thoroughly clean their composites of the underlying issue with the dirty plastic & wood fiber always do while generally spending less & less time labor & money to keep them clean over their life cycle.

Thanks for the testimonial. We once had a PayPal payment option. They charged a substantial service fee which customers refused to pay & couldn't be added to the cost of the product. Due to lack of use, we removed it.

“My husband loves the product! He uses it on our white vinyl horse fence which was installed in the year 2000. It turns green with mold. once cleaned, it looks like the day it was installed. He use to use Clorox, but it doesn't work nearly as well, requiring a lot more scrubbing and the mold returned faster. We use it on our TimberTech composite deck which was installed in 2016, siding and anything that gets mold. We're located in PA. I just ordered more.”

“We've used the protect for 4 years on our first generation Trex. Evidence of years of neglect disappeared, and we continue to use it on a maintenance schedule. We had some product splash on a glass storm door and first floor windows below the deck. Sticky and stuck-on. The solution is home-made, one I use to bring back badly stained glass shower doors: 1 t. Dawn 3-4 T Hydrogen Peroxide 2 T Baking Soda Simple cleaning does it and eliminates the project of taking off nearby glass.”

Thanks for the testimonial! It's always best to protect items not intended to be Corte Cleaned; specifically glass & aluminum, etc. as stated on its label directions. Painters plastic works great, as shown in the demo video. We gave you a discount on your order to show our appreciation for taking the time to write your review.

“As a rental house our decks were filthy, people don't clean up after themselves, so wine, food and suntan oil really left decks in a mess. Corte-Clean did a marvelous job, a little effort using the product but definitely worth it.”

If you are looking to use less effort keeping your composite deck clean, please consider using Corte Clean "at least twice yearly, spring & fall, or when stains occur." This is how Corte Clean is designed & intended to be used. Proactively using Corte Clean is proven to keep composites clean of all common stains while generally costing less time, labor & money with less effort. Thanks for the testimonial.

“Don't waste your time or money with anything else with Trex. Once the deck was initially cleaned with Corte Clean, I now routinely maintain it spring and fall. I now use less than 1/2 the product to keep it clean. It takes a lot less time and effort. I spray it on like clockwork or when I first notice stains, let it dry & let the rain rinse it off. Usually, the stains are gone. If there's stubborn stains, I repeat the application, but this is generally only necessary when I forget to be proactive. My deck looks brand new minus the sun fading and it is over 10 years old.”

“Simply the BEST composite deck cleaner. Once you use it, you’ll never try anything else. Removes all stains with very little elbow grease. Spray on with pump sprayer, let sit for 10 minutes and hose off. I have been using Corte clean for 11 years. It should be available everywhere. Thank you Corte Clean”

“We built our home in Bend, Oregon in 2001 with Trex decking. I'm a repeat Corte Clean customer. It works very good. I had some extra, so I gave it to my neighbor, whom I believe has Timbertech or Choice deck. He's now very happy too! I just ordered more.”

“I have used CorteClean for a number of years with great results but somehow last year during covid-19 I did not use the product and then this year when I cleaned my deck the stains did not come out. So I called Greg the company owner and explained what happened and he said the product I was using was more than a year old and had past the expiration date so it probably was not strong enough to clean the stains. He gave me a special price and I ordered a new bag of the product and applied it exactly according to the instructions using the Four Scoops per gallon ratio and I left it on the deck for one day until it rained and then the next day it came out perfectly spotless ( pictures attached ). Thank you Greg!”

Corte Clean has a "Best If Used By:" date that's exactly 1 year from the manufacturer date. Product used beyond this date will generally fail, as you've unfortunately noticed, because it looses strength. That's why we put the date on every bag. We don't provide a "Guarantee or Limited Warranty" beyond this date as stated on the bottom of every bag, because we know it will likely fail. If you choose to purchase Corte Clean from the website, please make sure you use it before it goes beyond this date or you likely won't be satisfied. The fresher it is, the better/faster it generally works. We only ship the freshest product available which is generally made every few weeks. YOU WIN A FREE BAG OF CORTE CLEAN FOR YOUR TESTIMONIAL WITH A PICTURE, so call us next time you need it.

“My Trex deck was installed in 2003. I bought the house about 10 years ago. It is near the water in Newburyport, MA. It gets difficult to remove green mold. My neighbor recommended Corte Clean. I have been using it for 3 years. You have a great product!”

Thanks for the testimonial! You WIN a FREE BAG of Corte Clean. Please call next time you need it and remind us of this review. The recommendation & use of "other products", especially those that are "homemade" and/or especially those that contain scientifically unproven sodium hypochlorite to clean common black mold has been a serious problem in the composite decking industry for owners for all the reasons stated on the Corte Clean website. Unfortunately, unscrupulous composite manufacturer's, retailers & websites continue to recommend & sell dangerous products or concoctions of chemical's for this purpose. Why do you think they do this? Think increased profits might have something to do with it? It'd be hilarious as to the scam they are pulling off if it wasn't so laborious/expensive & dangerous for composite owners. Unfortunately, most uneducated composite owner's think they'll be saving a few bucks by using perceived inexpensive product(s) or homemade concoctions which ultimately can end up costing a fortune. That's exactly what composite manufacturer's, retailer's and websites want you to do.

“I've been using Corte Clean for 12 years to clean my Trex deck, spring and fall, in Michigan. When I'm done, it looks clean and new. Last year, 2020, I went to Northville Lumber, and they were sold out, so I ordered online. I used one back in the fall of 2020, with the usual results and was going to use the second one this spring, but it was always raining so the opportunity did not materialize. The package I just used says best if used by 051521. For the past 11 years, I stored them in the climate controlled basement. This past year I stored it in the garage, which isn't climate controlled. The results were disappointing, it did not clean well at all, even after two applications. I used up the entire package doing a third time and it still looks bad- better, but not clean. Lesson learned. I just ordered more fresh Corte Clean.”

Thanks for the testimonial! We've given you a FREE BAG of Corte Clean with your order for bringing awareness to the "Best If Used By:" date and proper storage. Like most things in life, chemicals such as those in Corte Clean degrade over time. When they degrade they don't clean as well. Storage of Corte Clean in a "dry, cool, area", with consistent temperature, like a basement, especially those that are climate controlled, is best, as they degrade more slowly so they perform for longer periods of time. Garages, where temperatures greatly fluctuate, hot & cold, especially in MI, is not recommended.
