Composite Deck Cleaning Facts
Corte*Clean® cleaning a heavily mold stained Lowe’s® ChoiceDek®.
Notice how the black mold stains no longer spot, but have infested the composite boards, on the above ChoiceDek®. This generally results in deeply rooted worst case mold stains infesting each composite board. This was caused by the previous routine use of “sodium hypochlorite”, which was recommended by the manufacturer of this deck, to clean it of mold. The owner did this until it no longer had any effect. Perhaps you have experienced this? Scientifically speaking, this explains why so many composite owners have had much frustration and aggravation in keeping composite decks clean of mold. Scientifically, this will be explained on the coming “Advantages page” of this website. As you can see, Corte*Clean is foaming up and cleaning this nasty deck.
Corte*Clean® cleaning mold stains & tannins from exposed wood fiber.
If Corte*Clean® has not been used before, it will clean composites of the tannin, from the dead organic material, such as wood fiber, from which most composites are partially made. Unlike sodium hypochlorite and/or oxalic acid based products, which only bleach then brighten the wood fiber, Corte*Clean® will stop what is commonly referred to as “tannin bleeding.” Failure to thoroughly remove the food source that fungi feed on generally exacerbates fungus growth.

Tannin Bleeding. Composite above is dry and needs another application of Corte*Clean, as the wood fibers are not cleaned of tannins.
It generally takes two (2) “repeat” applications of Corte*Clean® at “maximum strength” to clean new composites of tannins and stains when first noticed. A bag of Corte*Clean® is designed to clean approximately “300” square feet of composite at “maximum strength” with two (2) “repeat” applications. If the composite intended to be cleaned has excessive tannin bleeding, has been neglected, or previously cleaned with other products, especially those that contain sodium hypochlorite or oxalic acid, additional “repeat” Corte*Clean® applications may be necessary to thoroughly Corte*Clean®, requiring the purchase and use of additional Corte*Clean® to initially clean the composites.
When Corte*Clean® is proactively used, as it is designed and intended, prior to stains occurring, one (1) bag of is designed to maintain the clean appearance of approximately 500 square feet of composites, with one (1) application, twice (2x) per year, Spring & Fall, or before stains appear. It is always best to proactively Corte*Clean® composites before it rains or the composite receives moisture. Proactively Corte*Cleaning® prevents the build-up of mold spores, pollen and other debris that cause fungus stains, while naturally rinsing any remaining Corte*Clean®, saving time and water.
