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"!!!

“Corte-Clean keeps our deck looking new--year after year.”

“The product works on it's own. Not labor intensive at all. Also your customer service is excellent. Spoke to representative on the phone while cleaning the deck and he solved the minor issues. Nice to know there are still some good American Companies left.”

“After only a few years of use my deck had all these ‘stains’ and black spots and was disappointed I bought it. After searching the internet I found Corte clean. I am pleased to say after using this product, going by the instructions, my deck looks like new! Now regular maintenance!”

Thank you for the black mold stained BEFORE (left of pictures) & AFTER (right of pictures) of what looks like Lowe's ChoiceDek. Following "the instructions" is the key to keeping composites clean & looking "like new!" Unfortunately, most composites require "regular maintenance." Fortunately, when Corte Clean is used "at least twice yearly, spring & fall, or when stains appear" at the "routine cleaning" reduced or UP TO 1/2 strength, one generally uses less Corte Clean, generally costing less money/time/labor. Most that neglect to properly proactively Corte Clean notice those stains caused by molds returning first & don't even notice that it clean all other common stains from grease & oil, rust & tannin's and more. Proactively Corte Cleaning composites before they receive moisture and stains return or deeply saturate on a routine basis is the key to generally spending less while being more eco responsible because less of our 100% biodegradable product is used. Thank you for your testimonial & you win a free bag of Corte Clean. Please call next time you need it.

“We've tried other products in the past to clean our TimberTech deck in Massachusetts. We now only use Corte Clean. I ordered more today.”

“I've had Trex for about 15 years. Corte Clean is the only thing I have ever used. It works pretty darn good. It has been so rainy in Wisconsin this year, I just ordered more to clean it.”

“I bought a composite deck 6 or 7 years ago, to replace a wood deck, thinking I never had to do anything to maintain it. I think it is TimberTech, as I have friends that work for the Trex Company here in Virginia. After about 2 years, it got black mold spots. I stumbled upon Corte Clean online. Corte Clean is the best thing I have bought to clean it. I have now been using it 3 or 4 seasons. I use to buy it locally, but just bought it online, as I want the freshest product available.”

“We have a Trex deck around the pool in NY that is 6 or 7 years old. It gets grey mildew spots. I love Corte Clean and have used it three times in the past. I have told many people about this great product who now use it too.”

“Started using Corte 3 years ago. My trex deck was badly stained. It took a little longer the first couple times I cleaned but now it’s much easier. Your helpful hints each year are very helpful. Appreciate your reminders. I use Corte twice a year as you say and my deck looks great. A Great product. I’ve recommended it to several people. Thanks”

“I can't review the product yet. Not until I may need to use it. Right now I am just reviewing the customer service. Talked to Greg the owner. Told him the stains on my Trex deck and before automatically selling me his product he suggested other means of cleaning that may resolve my issues before I spent money on his heavy duty cleaner. It's good to know there's still some quality customer service and honesty in this country.”

“Corte Clean is the best product I have used. It makes my composite deck look brand new. I purchased my deck from Lowe's and live in Virginia and love it. Ain't nothing no better.”

“We've had a Trex deck for approximately 10 years in Illinois. We had used other products in the past. We use to buy Corte Clean locally, at a hardware lumber store. They stopped carrying it??? I went online and now buy it directly. It is fresher and works better. We have alerady cleaned our deck this spring. I just bought it for a teacher friend with a dirty moldy dirty deck and am going to help her clean it.”

“10 Year old Trex deck in NJ. I have purchased Corte Clean 3 or 4 times in the past to clean deep dark mold. Ordered more.”

“We routinely use Corte Clean. The mold really isn't that big of a deal any more.”

“My Trex deck and vinyl fence is in Philadelphia. They get mold. I have previously bought and used numerous bleach products. Don't use them, they don't work! Don't waste your time. Corte Clean works miracles, not just on Trex, but vinyl too. I tell everyone about it. If it doesn't work for you, you are improperly using it. I have been routinely using this product for years and have bought more to again clean my composites.”

“I have a timber tech gray composite deck with white azek custom made large flower boxes. I have used the Corte Clean product every spring since I built the deck before I take out our outdoor furniture and accessories. After the fall and winter here in southern Connecticut the deck and flower boxes have green algae stains and are very stained from the falling leaves. This product works outstanding, as long as you follow the instructions. It does not harm our Koi in our pond which is located right off of our deck or my wifes numerous flowers surrounding it. It its well worth the investment. I am a Corte Clean user for life !!! Give it a try I think you might be surprised with the results..”

“I've had ChoiceDek for about 15 years. I've tried many products that contain bleach and vinyl siding cleaners to remove mildew. Corte Clean does the trick. This is good stuff.”

“My composite deck is a mixture of TimberTech & Trex. It is located in Ohio. I have been using Corte Clean for 8 years to keep it clean of mold, spring and fall. Unfortunately, this year, I missed the spring cleaning, but have just ordered more to clean it.”

“We have a Trex deck in Ohio under a maple tree. It doesn't get much son. Corte Clean works. It is good stuff. Our neighbors have come over, that too have the decking, and wonder how we keep it so clean. I showed them the bag of Corte Clean. They all now use it too. I just ordered more for the fall cleaning today.”
