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.”

“We have had a composite deck for ~15 years. We have tried other deck cleaners over the years, but Corte Clean is the ONLY one that gets our composite deck clean. You do need to use the product as described on the instructions and it works perfectly every time!”

“Works great on my composite deck. Spray it on. Let it soak and rinse. 30 minute job on my 300 square foot deck. Looks great all summer long. My neighbor spends hours with his power washer.”

Thanks for the testimonial! Please let your neighbor know that using a pressure washer for mold stains is like pulling weeds from a garden or lawn, not getting the roots, then turning on the sprinklers. This generally results in the stains rapidly returning; wasting their valuable time/labor/money while exacerbating the problem and can permanently scar/damage composites. Perhaps they've noticed this already? Thanks again for the testimonial!

“I use Corte Clean twice a year on my deck. When used properly does an excellent job. Have used over 10 years since my composition deck was built. Highly recommended!”

“I have used this product for about 9 years. It definitely works. If you're not happy with results its user error. I know, because it took me a while to figure it out. For the most part, after using Corte-Clean for the first time, I realized I needed another bag to get really good results. Since I started out with one bag, and was too cheap to order another, I tried to stretch the " dosage " and thats where user error comes in. I have Trex deck and after a Cleveland winter, the black spots covered pretty much the whole deck needing a concentrated cleaning. In which case, you go through one bag really quick.”

When you first use Corte Clean, you generally need more to remove the tannin's from the wood fibers, which generally bleed yellow, until thoroughly Corte Cleaned. If the composites are made from recycled plastic, this generally requires the additional repeat application of Corte Clean to thoroughly clean. If other chemicals, specifically those that contain sodium hypochlorite, such as chlorine bleach or unscrupulous deck cleaners, this generally requires even more Corte Clean to thoroughly clean. Once thoroughly Corte Cleaned, generally less is necessary when proactively used to keep composites clean, as you have noticed. Thanks for the review!

“I covered my 16x40 weather-treated deck with Quick Cap composite planks six years ago and tried cleaning it with Simple Green mixed with bleach, which didn't work very well. I found Corte Clean during an Internet search, saw the reviews and ordered some. The first cleaning was the most difficult but every year I'm getting more familiar with how it works. I found that using warm water and a paint mixing attachment on my battery drill works best to dissolve all the cleaner granules. I spray with a one gallon Chapin sprayer, keeping the deck wet all the time then doing a little scrubbing with a stiff brush on tough spots. One bag of Corte Clean can do my whole deck. I'm extremely pleased!”

“I live in PA and have a Trex deck that was installed in 2010. It gets black mold. My wife ordered Corte Clean for the first time around 2012. I have since used it spring and fall. It becomes easer with every use.”

“I installed a composite deck from Lowe's approximately 10-15 years ago. I believe it was called Choice Deck. The salesperson from Lowe's recommended Corte Clean. My deck looks great and like new once I have cleaned it. I installed the same deck at my mom's a couple years later. I use Corte Clean on it too. It looks the same. I tell everyone that has a composite deck about Corte Clean.”

“We have a 16 year old Trex deck in Massachusetts. It looks brand new. We have been using Corte Clean almost since it was new. Corte Clean works like a magic eraser. One year we forgot to clean it and were worried Corte Clean wouldn't get the stains out. Not a problem.”

“We installed our composite deck approximately 23 years ago in Ohio. We discovered Corte Clean thereafter. It is wonderful! We recommend it to our friends. I have forgotten the name of our decking. It cleans the deck so well, you can see the recycled plastic from which it's made. Our deck still looks brand new.”

“We are now on our second home with a composite deck. The first home was an older composite that was not properly cared for. Using Corte Clean worked very well. This made me a believer in the product. In our current home the deck is new. Now we use Corte Clean each year and it's a simple maintenance process that makes the deck look clean and new each year. Would I recommend Corte Clean? My brother-in-law let their deck go for 20 years without cleaning. It was so bad I wasn't sure how it would clean up. I purchased the Corte Clean for him. For his mold and mildew I was concerned it wouldn't do a good job. It took some light scrubbing cause it was so bad, but it made a huge difference!! "WOW" was what my brother in law said. I tell everyone I know about Corte Clean and encourage them to give it a try. When you do it every year, it's spray on and rinse off, no scrubbing needed just as the directions tell you.”

“I live in rainy Washington State where mildew and mold are constant during the Spring and Fall months. We built a Timbertech deck thinking we wouldn’t have to clean and stain it each year. We chose gray for the color to match our house. Six months later we realized that our gray deck had mildew and needed cleaning. In addition, we have a Sequoia tree near the deck that sheds bark and needles with tannin that stains the deck in the fall. I found Corte Clean on the internet and got it because it did not contain bleach. I’ve used Corte Clean for maybe ten years. Twice a year, in the Spring and Fall I clean the deck and it looks great. It even removes tannin stains on our light colored deck. I also spray plastic deck chairs that are outside all year round and they easily come clean. Corte Clean is the only cleaner I will use on my deck.”

“This the only product for composite decks that really works for my 3 decks. Recently, worked on some nasty suntan lotion that left an ugly dark stain. Soaked my stain in the sun and scrubbed lightly then rinsed With my hose- no need for power wash- and did the rest of the deck- spectacular results. My 10 year old decks look new as I clean them with this product every 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.”
