Shrinkit mold7/14/2023 ![]() ![]() Proactively routinely using Corte*Clean®, at least twice yearly, Spring & Fall, at the reduced strength, prior to the composites receiving moisture is the best way to insure composites remain clean, even if the composite looks clean.įailure to proactively Corte*Clean® composites generally results black mold stained composites, when the composites receive moisture, if mold spores are in the air. If the spores are removed from the composite, prior to the composite receiving moisture, mold stains can not generally occur. If properly proactively Corte*Cleaned®, before the composites receive moisture, hatch, and root into the composites, it generally takes a lot less labor/time and Corte*Clean® (expense/money) to maintain a composites clean appearance. The below photo is what mold stains look like after mold spores (seeds) land on composites, receive moisture, grow and root into composites. Picture of a ChoiceDek® Plus® with black mold stains rooting into the recycled PE plastic & Oak wood fibers from which it was made.Ĭommon mold stains generally start out as black, oily looking, spots on composites when it appears. Unfortunately these composite owners don’t find out that most composites get dirty, with all kinds of common stains, including those from common black mold stains and other common stains until they shows up. Rather, composite owners choose to believe claims that composites are absolutely “NO MAINTENANCE” and will never need to be cleaned often propelled by the uneducated at retailers or installers. Unfortunately most composite owners do not read composite literature before purchasing and installing an expensive composites, which generally state to clean at LEAST twice yearly (2X), Spring & Fall, or when stains appear, so they are unaware. Is moisture getting in from the end cuts & screw holes, watering the fungi allowing it to grow? Will this lead to de-lamination, especially in freeze thaw environments? Is that black mold growing under the “CAP”? If so, we don’t believe any cleaner, including Corte Clean ®, can get under the PVC “CAP” to clean the mold stains growing in the wood & plastic core. Newer 2nd generation PVC “CAPPED” composite with recycled wood & plastic core. Unfortunately, most of these yet unproven composites haven’t stood the test of time & some owners are already starting to have issues. Manufacturers generally disclose that fungi can occur as “biofilm” on these products exterior. The second generation of composites, which are generally made from PVC exterior “CAP”, with a recycled wood & plastic core, state “mold & mildew” and/or “fungus” are only claimed to be “resistant”.
