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"!!!

Does a great job of getting the winter dirt off our deck including green moss! We have used this product for several years now.

Live on Colorado and the harsh weather can wreck havoc on your deck. Used the cleaner on 2015. The results were wonderful. Make sure to rinse or cover objects before starting. It will leave a trace on Windows and furniture. They recommend this as well. Watch the video to get the process down. Will order again and will maintain my Trex deck. Highly recommend this product.

I have been using Corte Clean on my composite deck for 2 years and it does an excellent job of removing mold and dirt. You have to follow the directions carefully and use it in the Spring and Fall here in the Northeast where there is much moisture. Whenever I called the company they were very helpful. If you are in a store and it is hard as a rock, do not buy it. It is outdated. I buy it online from Corte Clean.

After having tried nearly every other cleaner on the market, I discovered that Corte is the most effective and longest lasting cleaner available for my composite decking. There is no reason to ever use anything else.

This cleaner did a very good job with algae control and general spot removal. The foaming action seams to penetrate the surface of the deck better. Just make sure you use it before the expiration date.

product does the job best of all tried. The only slight downside is the delay due to the waiting-period for each app to work.

I have tried several composite deck cleaners over the years and Corte-Clean worked best for me. However, it's a LOT of work, the product is very expensive, I almost always have to do two cycles of cleaning and I still have 5 to 10% of the dirt / mold remaining when finished. I would also feel better about this survey if it was addressed to the right name in the e.mail. Joel ALtus

Mr. Altus, Thank you for the review! If you have previously "tried several composite deck cleaners", cleaning up the mess they cause, especially if they contained sodium hypochlorite, the active ingredient in Chlorine bleach, which exacerbates mold issues can make it "a LOT of work", as you unfortunately experienced. When Corte Clean is proactively used, as its label directions state, "at least twice yearly, spring & fall" from the time composites are newly installed, it's never "a LOT of work" and is a whole lot less "expensive"! When using Corte Clean proactively, you should "Use up to 2.5 Scoops for routine cleaning" per gallon of water. Because you are using Corte Clean at 1/2 strength, you are spending 1/2 the money making it a lot less "expensive". This is why the Corte Clean label directions state “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. A white residue may remain until thoroughly rinsed.” It is best to proactively apply Corte Clean prior to the composite receiving moisture from rain or snow, as the natural moisture will rinse it. Always “Thoroughly rinse composite prior to using.” It generally takes “two cycles” or repeat applications to a thoroughly dry composite to remove stains when they are not routinely Corte Cleaned "at least twice yearly, spring & fall or when stains appear.” This is why we put enough Corte Clean in each bag to clean approximately 300 Sq. Ft. at maximum strength with “two cycles” or repeat applications. Proactively using Corte Clean at the reduced strength, the bag is designed to cover approximately 500 Sq. Ft. in the spring and 500 Sq. Ft. in the fall, or a total of 1,000 Sq. Ft. As you can see, this makes Corte Clean a lot less expensive! Now factor in that Corte Clean is not just a mold & mildew stain remover. It also cleans grease & oil, rust & tannin stains, and most other stains. You don’t have to purchase and laboriously use one product to clean mold & mildew stains, a second product to clean grease & oil and a third to clean rust (generally caused by the mold & mildew product) & tannin stains. This makes Corte Clean even less “expensive”. Corte Clean is actually the least expensive PROVEN product on the market when all is considered. If you “still have 5 to 10% of the dirt / mold remaining when finished”, you really need to do another application, as this is why the Corte Clean label directions state “Rinse with water. Water magnifies stains. If stains are still visible, repeat application process”. This in conjunction with “When Corte Clean no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces.” Should be applied to your composite deck to insure it is thoroughly cleaned and mold doesn’t immediately return when it receives moisture. Please see www.corteclean.com or call us to thoroughly discuss as we are really interested in making sure you spend less time and money Corte Cleaning your composite deck.

We had dark stains on our composite deck and could not get them clean. We were having the whole house power washed and they were unable to remove the stains as well, but said a prior customer had luck removing them with corte. We looked it up online and ordered right away. It is easy to use if you follow the directions. Our decks looked like brand new. That was 2 years ago. We will be using it again this Spring as some other spots are visible and we know corte will remove them.

We replaced our pine deck with a "maintenance free" TimberTech deck because we were sick of the upkeep. To our chagrin we realized after a couple of years even these types of decks require annual maintenance to look their best. Regular cleaners and scrubbing wouldn't remove the blackish spots so we did an on-line search for cleaners and found Corte Ckean was recommended for TimberTech. We found it at a local hardware store and tried it. One small bag easily cleans our approximately 15x21-foot deck. After thoroughly sweeping, hosing and overnight drying, we apply Corte Clean the next morning with a pump sprayer in full sun. Stubborn spots require a light scrubbing and re-application of the cleaning solution. After a morning of work the deck looks like new again! Local stores stopped carrying it so we're grateful to be able to order on-line. If it weren't for this product we probably would have replaced the deck with a patio by now!

I have used Corte Clean for several years now on my composite deck. It is easy to use and does a great job, especially on removing the sticky bud casings from cotton wood trees. Have not found another product that works as well and my deck looks great after I have finished.

We have used Corte*Clean on our deck for the last two years. We are very please with the results and the simplicity of the treatment. We will continue to use Corte and recommend it to anyone wanting to clean their composite deck.

This is a very good product. The only real downsides are that it is difficult to mix/dissolve even in warm water. Also the fact that the temperature needs to be just right during application causes the product to dry quickly. With a large deck it was more work than expected just keeping the areas wet. I will use again though.
