“I’ve used corte clean twice in the four years I’ve lived here and have been pleased with the results.”

Posted 4 years ago

“Our TimberTech deck is thirteen years old. Its color is beige and we chose to have the "grain" side up installation. We cleaned with Corte Clean in July only because where we live (Omaha, Nebraska) the weather is very unpredictable and, many times, the weather does not meet the requirements to use the product. Plus, it was just time to clean the surface of dirt and mold. Our deck is mostly in shade with our house and a tree blocking the assisting sun. The temperature at application was between 75 and 90 degrees, it took six hours to clean. Corte Clean worked wonderfully for us. I think at the higher temperatures we had, the necessity of sun is lessened. We used a maintenance level of cleaner (2.5 cups of cleaner) and, even though it had been two years since the last cleaning, it worked its magic. Using Corte Clean is rather labor intensive but well worth the effort. Thank you Corte Clean.”

TimberTech composite decking located "mostly in the shade" should definitely initially be cleaned between "65 to 85 F". This allows the composites to expand, pours to open, so the Corte Clean can deeply clean & remove the stains, especially those caused by molds! Depending on how many Square Feet your deck is, it can absolutely take "six hours to clean", especially if neglected for "two years since the last cleaning", allowing the stains to deeply saturate or root. It is highly recommended you proactively Corte Clean your TimberTech, as recommended in the TimberTech "Care & Cleaning" literature and on our product's label directions which states "at least twice yearly, spring & fall, or when stains occur" at the reduced "routine cleaning" strength to prevent deep stains. If you do this, it should generally only take you 45 minutes to an hour to apply & you should be using up to 1/2 the Corte Clean, or less, saving you MONEY. DON'T skip the final label direction that states "When Corte Clean no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces [ESPECIALLY IN SHADED AREAS]. 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 before it rains & let the natural moisture do the labor. Please call if you wish to thoroughly discuss, as we wish to make sure your TimberTech remains clean for as long as possible with the least amount of cost, time & labor. Thanks for the testimonial!

“We installed a 62 1/2 foot Trex deck in 2016 in the mountains of Georgia. I worked for ACE hardware for 20 years. A friend of mine in Pennsylvania, that owns a ACE store recommended Corte Clean. Told us it was the only product to use. We used it last year and just ordered it again this year. This is a wonderful product.”

“Corte Clean is our go to deck cleaning product for our composite deck. There's no other cleaner we've found that can do such an amazing job! The process of cleaning is simple...we have a rather large deck and my husband and I can have the entire deck cleaned in an hour or so with the help of Corte Clean. I've even managed it by myself. We built the deck roughly 12 years ago and, after each Corte Clean cleaning, it looks brand new! Prior to finding the product, we looked into having the deck professionally power washed and it didn't come out that well and the price was hefty. Corte Clean leaves our deck looking new and for a very reasonable price. We are huge fans of this product and use like clockwork each and every year. Thanks Corte Clean!”

“🙂 hi I bought your product last year but never got around to using it until today Just thought I would let you know that it was easy to use any just unbelievable results I’ve use many products and nothing would clean the tree sap and other dirt I could go on and on but suffice to say I am so happy I found corte clean Keep up the good work Your product is awesome 👏”

Thanks for the testimonial! Now that your deck is clean, please consider proactively using it "at least twice yearly, spring & fall, or when stains appear" at the reduced "routine cleaning strength". Those that do generally end up spending up to 2/3rds less time/labor & up to 1/2 the money because they are using up to 1/2 the Corte Clean. Don't skip the final label direction 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 any time it receives moisture until thoroughly rinsed. 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 & allow the natural moisture to do the work.

Thanks for the testimonial with pictures! You win a FREE bag of Corte Clean. We'll ship it today. We want to make sure your composite deck remains clean. Please use it to proactively apply Corte Clean "at least twice yearly, spring & fall, or when stains appear" at the reduced "routine cleaning" strength, preferably before it rains, so the natural moisture can "thoroughly rinse". Hopefully you didn't skip the final label direction 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 any time it receives moisture until thoroughly rinsed. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse composite prior to using." With proactive use, you should generally notice your deck staying clean for longer & longer while using less & less Corte Clean per gallon of water. When it rains, stains caused by spills such as grease & oil, rust, tannin's, etc. generally disappear. Please call if you wish to thoroughly discuss. Happy 4th!

“In 2011 we installed an AZEK composite deck in New Hampshire. Our son recommended Corte Clean when our deck started getting black and green mold in addition to other stains, as he too has a composite deck. Corte Clean does a really good job. We have been using it for years.”

Posted 4 years ago

And the AZEK company tells us the PVC composites they manufacture don't need Corte Clean. LOL! We thank your son for the recommendation. Next time you all need our product, let us know. You've earned a discount. Thanks for the order today.

“I have used this product for the last five year and there are no other products that produces the results this product does. I have a Trex deck in Virginia and the product removes all of the black stains on the deck.”

Posted 4 years ago

“I purchased this product, based on recommendations. I had blackish spots on my light grey composite decking. I cleaned it throughly, but still had these darn spots. I searched for how to remove these spots, and saw a lot of recommendations of this product. I followed the directions for this cleaner, and could not believe the results. It’s foams up the dirt, and then you just rinse it away. Tougher spots need a little agitation with a soft brush, but that’s it. Attached you can see the cleaned boards and next to it, the spited boards I hadn’t cleaned yet. What a difference. I have already repurchased this product, in anticipation of cleaning my dock, since it is eco friendly, and plan to reclean everything in the fall. I highly recommend this product. It did exactly what everyone said it would do.”

Now that you are happy with Corte Clean, we wish to make sure you are spending less time, labor & money keeping your composite deck clean. Proactively using Corte Clean, as stated on it's label directions, "at least twice yearly, spring & fall, or when stains occur" at the reduced "routine cleaning" strength is the key, preferably before composites receive moisture and stains occur or deeply saturate. Don't skip the final label CRITICAL direction, 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 any time it receives moisture until thoroughly rinsed. 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 so the rain does it naturally for you. Thanks for the testimonial!

“I have a Tendura composite decking covered porch, which was installed approximately 20 years ago, and is no longer manufactured. It's located in Virginia. Corte Clean is the only product that gets the mold stains out. I use to use chlorine bleach. It took two seasons of cleanings to get the impeded stains out the chlorine bleach caused. Additionally, don't use Soft Scrub, as it took several years to get the white out that this product caused. I've been using Corte Clean now for years. I use to buy it locally, but they stopped carrying it, so I now order online.”

Posted 4 years ago

We try to warn composite owners about the use of chlorine bleach or other sodium hypochlorite based products for cleaning mold! Unfortunately, most go down that path, exacerbating mold problems, often at the recommendation of manufacturers & retailers that ignore science in-order to promote & profit from The Chlorine Bleach scam . The longer one routinely uses this biocide, the deeper the mold roots, the more it excessively bleaches the color of composites beyond what most manufacturers disclose under "weathering", the more repeat applications it takes to thoroughly Corte Clean. Unfortunately, sodium hypochlorite can cause irreversible corrosion to structural metal decking hardware, the #1 SAFETY issue in the decking industry that is 100% preventable by not using it or other corrosive cleaning chemicals such as those that contain acids. Soft Scrub is a great product, but were not sure why any person would use it on a composite deck or for any purpose not stated on its label directions. Thanks for the review & call us for a discount on a future order.

“We did find 3 new bags at the Lehighton 84 lumber (I kept calling them because you had mentioned that they placed an order). What a difference fresh product makes!!!!! I figure if we have any left over we will use it in the Fall. I’m hoping if we do like April/September each year with one application, that it will do the trick to maintain the work we’ve done. Thanks again for the great customer support/service.”

The "Best If Used By:" date is critically important when cleaning deeply mold stained decking like yours. Once you get your composite deck thoroughly Corte Cleaned, proactively using it at the reduced "routine cleaning" strength is the key to generally spending less time, labor & money keeping it clean. Generally, this has the added benefit of composites staying clean for longer periods of time. Thanks for the testimonial! You've earned a discount on a future order, so just call.

“We have a TimberTech deck in MI. It gets grease and oil, in addition to mold, mostly in the shaded areas. We learned about Corte Clean from a friend and have ordered before. It's powerful and a great product.”

“Corte Clean Composite Deck Cleaner is the best product we have found to keep our deck looking as close to new as possible. We have had this deck since 2010 (uncapped version), and when it is cleaned with Corte Clean, it looks great. We are Seniors and are still cleaning it ourselves--mostly my husband, but I have done it a time or two in his absence. To quote him, "Cleaning a deck is never easy, but CorteClean makes it rewarding." Reading and following directions are also important to get the best result. Customer service has always been helpful and courteous. Their delivery has been reliable all the years we have used this product. Not sure if photo actually attached, but if it did, you can see the results of cleaning with Corte Clean on the boards on the right. Those spots on the boards on the left are after being wetted down, and before cleaner is applied. Amazing results!”

“We have Lowe's ChoiceDek that was installed in 2010. The deck gets mold, as it is located in Tennessee. We've previously used chlorine bleach products which appear to have damaged the deck. We switched to Corte Clean 5 years ago. This is a great product which I just ordered more today.”

Unfortunately, some manufacturers recommend chlorine bleach or other sodium hypochlorite based products for cleaning mold? They do this even though science has shown these products exacerbate mold, excessively bleach/fade or weather composites color beyond what is generally disclosed & corrode structural metal decking hardware. These are the top 3 complaints with composites that lead to the #1 SAFETY issues & expensive early replacement. This is known as THE CHLORINE BLEACH SCAM! Thanks for the testimonial & your order. We have discounted your order by $10 today.

“I have a TimberTech deck that was promoted as "no" maintenance. I should have done additional research before having it installed. Within 2 years I knew I had a problem. I found Corte Clean online and called to discuss my situation. They could not have been more helpful and gave me very detailed instructions. It was a lot of work because I had to protect the wood rails and aluminum balusters, but the result was worth it. Last year I tried a product that was guaranteed for 3 years and did not requires as much prep work. Five months later I am back as a 5 time Corte Clean customer. The results are much better! It is worth the time and money. I will be ordering more today. Thank you Corte Clean!”

Generally, it's a lot of work the first time Corte Clean is used because composite owners have neglected or used other products exacerbating cleaning problems, especially those caused by mold. This unfortunately generally costs more time & money/Corte Clean to initially clean. Protecting items regardless of what you use is key! Not only is Corte Clean cleaning the stains, it's cleaning the "tannin bleeding" from the wood fiber of which your TimberTech is made & can feed molds. We love it when people try other products & report their failure, especially those that have previously used Corte Clean. Unfortunately, these products can exacerbate cleaning issues, costing more time & money to again Corte Clean. It's almost funny that people spend $10K to $20K on average for a composite deck then try to spend as little money as possible to clean it? We don't blame them, but you get what you pay for with Corte Clean. Those that proactively use Corte Clean, at the reduced "routine cleaning" strength "at least twice yearly, spring & fall, or when stains appear" won't find a more cost effective PROVEN product for keeping composites clean, of all common stains, not just those caused by molds. Most other products have low perceived price points, and/or make lofty claims, but you have to buy two to four times as much, use it more often & buy other expensive products to clean specific stains. You get what you pay for with Corte Clean. Please call if you wish to place an order, as you get a discount for your testimonial.

“We used Corte Clean Composite Deck Cleaner on our very neglected almost 20 year old composite deck. This product did an awesome job with minimal effort. We will be using this product for future cleanings!”

“I've first used Corte Clean approximately 12 years ago to clean my Trex deck. I use to buy it from my local True Value in MD. They stopped carrying it, so I have tried many other, including some of the other oxy type products, as they are less expensive. The biggest difference is you don't have to scrub. Many of the other products are less expensive, but you get what you pay for. I'm back to Corte Clean and just bought more today.”

“1,000 Square feet of lite colored TimberTech 2010, which they discontinued right after we installed it because it didn't hold it's color. It gets black mold and stains around the flower pots where the irrigation overflows. Been using Corte Clean in MD for 6 years.”

“We have a TimberTech deck in Ohio. I originally thought we had a defective deck, as I thought black oil was coming out of it. I talked to the contractor that installed it and he recommended Corte Clean. Fantastic! Works.”

“Corte Clean Composite Deck Cleaner is the best cleaner of composite deck I have ever used.”

Posted 4 years ago

We wish every customer thought the same thing! Unfortunately, there will always be those that don't purchase enough to initially thoroughly clean composites or read, comprehend & follow it's label directions, therefor, no matter what we do, will never be happy. For us, accepting this fact, no matter how hard we try to help, has been difficult for us to understand. Thanks for this testimonial, especially after the last downer. You get a discount on your next order, just call.
