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"!!!

Our deck is under 2 large oak trees. The sap accumulates on the deck and when dry turns black. Until I bought your cleaner, I have been unable to remove the sap. It does take work but the results are worth it. I will upload before and after photos next time.

Thank you for the 5 STAR REVIEW! Please consider proactively using Corte Clean, especially under those "2 large oak trees", "at least twice yearly, spring & fall or when stains appear." Mix Corte Clean up, at up to the reduced strength on its label, spray on and let dry, as long as it is not turning dirty or discolored before it rains or snows. Stay off the deck until the Corte Clean is thoroughly naturally rinsed. This will generally SAVE you much "work", TIME & MONEY keeping your composites thoroughly clean, as Corte Clean will get under the sap stains in the pours of your composites and easily remove them from the bottom up rather than the top down when the deck receives moisture. Please call us if you wish to thoroughly discuss. (415) 924-9500 1

Cleans ChoiceDek composite decking of mold & grease from Lowe's without the stink of chlorine or causing rust stains around the Swan screws. Costs a lot less time and money to keep the deck clean than using other products for mold and barbecue mess. Highly recommend!

Corte-clean is fantastic. I wish i had "before" pictures of my deck this year--covered in black leaf stains. I gave my handyman a bag of Corte Clean and left the house. When I got home, it was as though I had just had a new deck installed. In the 10 years I've had my deck, i've never found anything like it!

This cleaner worked so well on our Trex deck that had been ignored for many years. It removed all the unsightly mold and spotted areas. It was quite time consuming preparing the area as we have a high deck over a cement slab with furniture underneath. All this had to be moved. When rinsing the deck we needed a person under it with a hose spraying everything, consequently getting soaked trying to hose the underside of the Trex. No matter how much we sprayed it still left white streaks. The top of the deck looked great, but sitting under it, it's quite unsightly. It's too high to reach with a brush to try and scrub while hosing. So, while the cleaner is quite effective, it is too hard to repeat the process for upkeep with only my husband and me tackling it.

I have staining on my composite deck from sun-tan lotion. The deck cleaner cleaned the deck and was able to lighten the stain area where I had brushed harder. I should be able to get out more and more stains out with a couple more attempts. This product has done more than others that I've tried.

Thank you for the 5 STAR Review! Unfortunately, most use Corte Clean reactively to clean a composite deck. When one uses Corte Clean reactively, like maintaining most things, it generally costs more time and money. Corte Clean is no exception, especially when cleaning sun-tan lotion or other common stains. If you are reactively cleaning this specific stain, one (1) Corte Clean application will likely not get your composites thoroughly Corte Cleaned, as you have unfortunately experienced. This is why the Corte Clean label directions state “•Rinse with water. Water magnifies stains. If stains are still visible, repeat application process. Composites that have tough stains, been neglected or previously cleaned with other products and/or sealed may require several applications & additional Corte Clean.” It is extremely important to do this to a thoroughly dry composite surface. We HIGHLY suggest you then follow the final Corte Clean 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 Corte Clean before your composites receive moisture from rain or snow. In the future, should you decide to generally spend up to ½ the money and approximately 2/3rds less time keeping your composites clean, we highly suggest you “•Use Corte Clean at least twice yearly, spring & fall, or when stains appear” in this fashion as the Corte Clean label directions state. Corte Clean will then soak into the pours of your composites and activate and re-activate any time it receives moisture until thoroughly rinsed. Generally, if sun-tan lotion or other common stains land on your composite deck and it receives moisture, the stains just disappear. This is because the Corte Clean has soaked into the pours of your composites and can easily remove the stain from the bottom up, rather than the top down. Additionally, if the sun-tan lotion has been blocking the sun from evenly bleaching/fading/weathering your composites, you may experience weathering issues which will generally go away in 10 to 20 weeks on their own. Please carefully review www.corteclean.com and call if you have any further questions, as we wish to save you time & money keeping your composites thoroughly clean. (415) 924-9500 X 1

Thank you for the ***** Star Review! Please consider never letting "tough stains, mold, moss, and grease spots" on your composite deck by proactively Corte Cleaning it. Generally "moss, mold" only occurs on composites that are severly neglected and not properly proactively Corte Cleaned "at least twice yearly, spring & fall, or when stains appear" as atated on its label directions. Proactively Corte Cleaning will generally save you up to 1/2 the MONEY and takes approximately 2/3rds less of your valueable TIME. The best way to do this is "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 Corte Clean before your composites receive moisture from rain or snow. If grease stains are noticed, immediately proactively Corte Clean it, as composites expand and contract with heat and cold, opening composite pours and solidifying the grease and oil allowing it become more difficult to clean. If the composites are then allowed to contract with cold weather and the grease/oil is allowed to freeze, it can be more difficult (cost more TIME & Corte Clean or Money) to remove, especially if Corte Clean is not proactively used. Please save yourself time and money keeping your composites clean by proactively using Corte Clean. If you wish to thoroughly discuss, please give us a call. (415) 924-9500 X 1

Wow! This cleaner just works, and the effort is minimal. I followed the directions in the video, which were very clear. The results were stunning. My deck looked as good as the day it was installed. We had a cookout with friends the day after I cleaned the deck, and everyone was so impressed with how beautiful it looked.

The top of my deck railing is composite wood and hadn't been cleaned in 2 years. I scrubbed it down with plain water two days ago and let it dry. This morning I sprayed on a coating of Cleaner,let it set briefly, sprayed on another coat and took the scrub brush to it. Then I sprayed on another coat and brushed it again. After about 20 minutes (it was still wet) I rinsed it off with the hose. Not everything came off but it looks 100% better. This didn't work as well as I had hoped but the rail was in bad shape. I wouldn't want to do the entire deck floor like this. Overall, I'm satisfied.

Thank you for the review! Are you aware that most composite manufacturers recommend proactively cleaning composites at least twice yearly, Spring and Fall, or when stains appear? Please keep in mind that Corte Clean was/is designed and intended to be used “at least twice yearly, spring & fall, or when stains appear” as its label directions state, not every “2 years” when stains have been allowed to deeply saturate or root and generally cost more time, labor and money to properly thoroughly Corte Clean, especially in Ohio where mold spores, moisture, heat & cold lead rapidly to dirty deeply stained composite decks. Please consider this in the future if you wish to save. While Corte Clean works great for reactively cleaning composites, its label directions must be carefully followed or time and money are wasted Corte Cleaning and the desired results won’t be fully achieved, as you have unfortunately experienced. We are not sure why you “sprayed on a coating of Cleaner, let it set briefly, sprayed on another coat and took the scrub brush to it. Then I sprayed on another coat and brushed it again” when the Corte Clean label directions clearly state “Allow composite to thoroughly dry before applying Corte Clean” and “Rinse with water. Water magnifies stains. If stains are still visible, repeat application process. Composites that have tough stains, been neglected or previously cleaned with other products and/or sealed may require several applications & additional Corte Clean.” The KEY to success is allowing Corte Clean to “thoroughly dry before applying Corte Clean” or one does the “repeat application process”. Applying three (3) Corte Clean coats, one after the other, without allowing “composite to thoroughly dry before applying Corte Clean” or re-applying Corte Clean is generally a waste of time and money and will not generally get composites thoroughly Corte Cleaned as you have unfortunately experienced resulting in “Not everything came off but it looks 100% better. This didn't work as well as I had hoped but the rail was in bad shape. I wouldn't want to do the entire deck floor like this.” Did you follow the final Corte Clean label direction of “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 Corte Clean before composites receive natural moisture from rain or snow. If you haven’t done this final step, please consider doing it, as it will likely remove any remaining stains, especially if you choose to proactively Corte Clean your composites in the future before letting your composites get into “bad shape”. Please call us if you wish to thoroughly discuss, as we wish to help you spend up to 2/3rds less time and up to approximately ½ the money keeping your composites thoroughly Corte Cleaned.

After speaking with the customer, his composite railing was approximately 15 years old. It had been previously cleaned 2 years ago. Corte Clean had never been used previously. The composite had heavy green fungus growth stains on it. Customer noted the composites "looked even better than when he wrote the initial review." Hopefully this customer upgrades review once Corte Clean directions have been completely followed and composites are thoroughly cleaned and allowed to evenly weather. We thank the customer for returning our call.

I have used this product for four years on my Trex deck. As long as you follow the instructions you will have excellent results. Make sure your deck is dry and leave the product on and keep it wet for the allotted time and you will have good results. Also make sure you check the date on the bag to be sure it hasn't expired old product will not have the same results.

Thank you for your FIVE STAR REVIEW! Please consider calling the Trex Company and telling them. In the future, please consider proactively using Corte Clean, "at least twice yearly, spring & fall, or when stains appear" as the product was designed and intended and label directions state. This generally will SAVE you TIME & MONEY. When proactively using Corte Clean, preferably before composites receive moisture and stains occur or saturate, Corte Clean should be used at the “up to 2.5 scoops for routine cleaning” per “1 gallon of water” strength saving money. One can apply Corte Clean proactively in any condition, day or night as long as the composites are thoroughly dry. This is why the Corte Clean label directions state “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 clean any time it receives moisture. A white residue may remain until thoroughly rinsed. Thoroughly rinse composites prior to using.” The best way is to “thoroughly rinse” is to apply before it rains or snows and the natural moisture rinses it saving you time. Please call us if you wish to thoroughly discuss. (415) 924-9500 X 1

Corte Clean worked as advertised, now that i know the process and timing i will use it again. I was using a pressure washer and this product seems to be a little easier and less time consuming. Hope it will also extend the life of the deck. Used on Timber Tech.

Thank you for the review! Pressure washers are excellent for prepping TimberTech prior to Corte Cleaning to remove loose dirt and debries. Generally, as you likely have noticed, one can get TimberTech 80% to 95% clean with a power washer alone, however, one can exacerbate cleaning issues with a power washer by driving the stains deeper into the pours and perminantly scaring or damaging the composite. If you choose to proactively "Use Corte Clean at least twice yearly, spring & fall, or when stains appear", you likely won't ever need to use a power washer again. Proactively using Corte Clean as TimberTech recommends will generally save you much time and money. 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).

The product worked fabulously...better and easier than I had anticipated. It's easy to mix and works quickly on the areas that need treatment. It will last for quite some time so it is well worth the money. And my deck looks brand new. I was careful when researching which products would be safe for my deck and this was the one... I have not used anything else. My deck is only 2 years old so will not need to try any other product.

After attempting unsuccessfully to clean my three year old grey composite decking with the products I use to clean my vinyl siding I turned to the internet and discovered Corte' Clean. Initially I purchased two bags and began the cleaning process. The results varied but when I called customer service to express my concerns they once again reviewed the cleaning process and ensured me that if I followed the process. The customer service person also asked about my location and went on to share that high humidity in my area was the cause of staining problems. They also suggested a cleaning schedule that would not only reduce the cost of the produce per application but would also reduce the effort needed. What I liked most about my interaction with customer service was that someone helped me who knew the product being sold. I use a squeeze to remove water from the service of boards to enhance drying between applications of the cleaner.
