PLEASE READ BEFORE POSTING A NEGATIVE REVIEW!!!

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 been using Corte Clean for many years on my Timbertech deck. I'm in Maryland and the mold on my deck is brutal, I use Corte Clean and the product brings the deck back to new. I would suggest using bottled water if you have well water as it dissolves much better.”

“I have a Tek deck in Columbia River Washington which gets mold. My daughter has one in Oakland California, which too gets mold. I ordered too much Corte Clean, so I gave the rest to my daughter. We both loved it. My neighbor has a Tek deck too. She saw how well the Corte Clean worked, so now she will be using it too. I have ordered more, but unfortunately, the weather isn’t quite right to clean the deck, so I will wait. I love the YouTube Corte Clean video. It reminded me to only use Corte Clean when the weather permits.”

“I’ve had an AZEK composite deck for 5 to 7 years. I get black mold and dirt in Illinois. The first year I used Corte Clean to clean my deck, I hired someone to clean it, as I didn’t want to do the work. I now use Corte Clean spring and fall; however I may do it three times this year. Corte Clean is a great product that I have ordered again this year.”

“I have a TimberTech composite roof deck which was installed in 2012. My contactor recommended Corte Clean to clean it. I have been using it once per year ever sense to clean bird poop, oil, dirt, black & green mold, etc. The deck gets lots of sun, so the mold isn’t too bad. I use a pump sprayer and stiff brush to clean the deck. The rain does an excellent job of thoroughly rinsing it. I just bought another four bags for my yearly cleaning today.”

“I had a Trex deck installed here in Pennsylvania in 2006. It has the Trex Railing. It began to get green mold and the occasional wine spills. I originally purchased Corte Clean from my local Lowe's. When they no longer carried it, I began buying it from its website. I believe this is my 7th season, so I think I have been using Corte Clean for approximately 10 years. I use Corte Clean to clean my deck every April and October and just ordered today.”

“Had used another composite cleaner previously which required many more steps and more preparation and did not even work as well as Corte. I highly recommend Corte cleaner”

We are sorry to hear you wasted time with another composite cleaner. Did the composite cleaner that you previously used contain sodium hypochlorite or oxalic acid? If so, please have a professional check your structural metal decking hardware (screws, nails, joist hangers, etc. to make sure it is safe. Corrosion caused by the use of corrosive to metal cleaning chemicals is currently the #1 safety issue facing composite owners that ignore structural metal decking hardware corrosive cleaning chemicals disclosures by following retailer, chemicals & composite manufacturer corrosive cleaning chemical recommendations! Hopefully you choose to use Corte Clean proactively, “at least twice yearly, spring & fall, or when stains appear”, at the “routine cleaning” strength, preferably before composites receive moisture to prevent stains. This is proven to cost less time & money to keep composites clean. Thanks for the review!

“Amazing Product We have Choice Decking on our porch, front steps and back steps with multiple stains/mold on all. After using many different products, Corte-Clean was the ONLY product that made any impact and removed most stains. This company REALLY does care and took the time and effort to work with me directly on how to remove the stains and care for my decking. My only regret is that I wish I knew about this product before wasting my time, effort and money on other products. Highly recommend this product and 5 stars to Greg, the representative I dealt with.”

Thank you for the review! Corte Clean will generally remove ALL the stains from your ChoiceDek, however the stubborn deep stains will generally come out with the proactive use of Corte Clean, if they didn’t come out during the initial cleaning. Please consider using Corte Clean proactively, at the reduced “routine cleaning” strength (which saves money), preferably before the deck receives moisture, to prevent new stains, while continuing to remove the most stubborn deep stains. If Corte Clean won’t remove the deepest stains from ChoiceDek, it is likely nothing will. Do not skip any part of the Corte Clean Label Directions, especially the part that states “When Corte Clean no longer turns 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 prior to using.” The best way to thoroughly rinse is to apply Corte Clean prior to it receiving moisture, if you wish to generally save time & water. Unfortunately, your previous routine use of the multiple other cleaning products at the recommendation of the ChoiceDek manufacturer, for cleaning the mold stains, grease, etc., in addition to the rubber mats you used to hide the stains, when the ChoiceDek recommended cleaners failed, made it more challenging to thoroughly clean due to the stains deeply rooting & saturating. This greatly exacerbated the cleaning issues with your ChoiceDek. Additionally, based on the photos your ChoiceDek, it has weathering issues caused by the stains & rubber mat blocking the sun from evenly bleaching/fading your decking. The weathering issue will naturally weather away once thoroughly Corte Cleaned, over time, by exposure to the sun. Those that follow the ChoiceDek manufacturer cleaning instructions, BE WARNED, it generally costs more time & money to thoroughly Corte Clean ChoiceDek once the multiple products they recommend ultimately exacerbate cleaning issues & fail while causing weathering issues. Please keep us posted, as we want to make sure your ChoiceDek gets thoroughly Corte Cleaned, stays clean for as long as possible, & you are spending the least amount of time & money keeping it clean. Corte Clean has been proven to do this specifically with ChoiceDek, by ChoiceDek owners, for approximately 15 years.

“This product worked wonders on my Timbertek steps and railings. Cleaned the mold right off. Then I used the had some solution left over and I treated my concrete patio. It worked like magic. With just a little scrub the concrete patio looked like new. An outstanding product.”

“I am a long time user of this product and a believer in its ability to keep black mold at bay. Our ChoiceDek has been in place for more than ten years now and I first started out using other products but none of them have performed as well as Corte Clean. I only need to use 2 to 3 cups per application and I do a cleaning each spring and fall.”

Thanks for the Corte Clean review! You likely meant 2 to 3 scoops of Corte Clean powder, not cups, for routine cleaning. If you are using cups, you are likely wasting money by using too much Corte Clean per gallon of water. The trick then becomes how little Corte Clean powder can be used proactively, per gallon of water, to keep composites clean. It’s kind of like trying to maximize fuel economy, of a vehicle, on a road trip, to save money. Proactively Corte Cleaning composites, before they receive moisture and mold stains occur, or other stains saturate, generally costs less money, time & labor to keep Corte Cleaned.

“Corte*Clean does a great job on our 10-year-old TimberTech deck. We've tried other products, but nothing works like Corte-Clean. This is the 1st year we had to deal with several grease spots - and we're happy to say they disappeared! We are so pleased with the appearance of our deck - it looks great. We are late cleaning the deck this year because of several months of heavy smoke in Medford, having roof work done and getting the house painted, so we were lucky to have beautiful weather in October to finish this project.”

“I have an AERT ChoiceDek Premium Plus composite deck which I purchased from Home Depot well over a decade ago, likely 2002 or 03. I was part of the class action lawsuit. They sent out a crew to clean my deck, but the mold came right back! They eventually refunded the entire purchase price of the deck. I then began purchasing & using Corte Clean from my local Lowe’s, lumber or hardware stores. This product keeps the mold at bay, so I have decided to keep my deck. They no longer carry it, so I began purchasing it directly from the company in 2013. I use Corte Clean spring and fall to keep my deck clean. The only problem we have had is related to the hard water here in Davidson, NC, dissolving the product when used at maximum strength, which has now been resolved with warm water and using less Corte Clean powder per gallon of water to keep my deck clean. Great product & customer service!”

“I have been using Corte Clean to clean my TimberTech composite deck of mold stains once per year. They generally come back where the deck doesn't get any sunlight. I should use Corte Clean more than once per year, but it has been hard to find a handy man. I just ordered more Corte Clean today and think I will clean it myself and begin using it more than once per year to keep the deck clean.”

“I bought my composite deck several years ago from Lowe's. It turns green and black with dirt and debris, especially where people walk and track it on the deck. I have only used Corte Clean, in the fall, to clean it. I use to purchase it at my local Lowe's here in Virginia, then from my local hardware store, but they no longer carry it. I called the phone number on the back of the bag and ordered it direct today. Corte Clean makes my front and back decks look like new.”

“I’ve used CorteClean for the last several years on my composite deck. (I don’t know the brand). It has always worked well. I cleaned again last Fall and it made a great difference in the Spring. I’m going to order more today.”

“I use Corte Clean to every 2 years to clean my TimberTech deck of mold. It generally takes this long for it to come back, usually in the shaded areas first. My deck was installed in 2003 in Minnesota. This product does a great job cleaning my 400 to 500 square foot deck and gets the brown dirt out too. I introduced this product to my neighbors and they now use it too.”

Thanks for the review! Generally, once the underlying infestation of funguses & tannin issue with the wood fiber, of which your TimberTech deck has been partially made, that can feed molds has been thoroughly cleaned, and “tannin bleeding” has been eliminated, composites start to stay clean for longer & longer periods of time. The key is to proactively Corte Clean composites more often than not for the first year or two, getting ahead of the problem, while using less and less Corte Clean per gallon of water, which costs less & less money and labor or time. If the mold stains are returning, you are waiting too long to proactively Corte Clean. Getting ahead of the problem is the key for those who wish for composites to stay clean of all common stains, not just those caused by molds, for less & less money & time or labor.

“I used Corte Clean on my trek deck and am very pleased with the results. This is the third time I have done this. This time I used the maximum recommended amount and it worked much better than in the past when I used the minimum amount. It looks great and plan to use regularly as I am sure I should but sometimes time is an issue!”

“I have Tendura composite decking, which is no longer manufactured. It is grey colored with wood grain. Most of the porch is covered. Where it gets sunlight and is exposed to moisture has faded and gets moldy. I installed the deck here in PA in 2006 or 07’. I didn’t know about Corte Clean until approximately 2011, when I started using it. I have used this product 5 or 6 times and generally only use it once per year. I just ordered it again today!”
