We started with the goal of creating a cleaner that actually worked for cleaning composites. We had previously used common brand name deck cleaners, other cleaners, chlorine bleach and home remedies we found on the internet or that were recommended by composite manufacturers (thank god we did not poison ourselves) with little if any success in an attempt to resolve mold staining and other common staining issues. They did not get the composites clean. We found that most cleaners only made mold staining and other common staining issues worse, especially when repeatedly used! There had to be a better solution. We then spent the next few years traveling around the United States, cleaning composite decks with different formulations, that were developed by several reputable chemical engineers with over 40 years of designing and manufacturing cleaning chemicals (one who actually owns a TREX® deck) that biologically/chemically/scientifically understood the many problems sodium hypochlorite, oxalic acid and phosphate based products cause, in an attempt to resolve claims related to cleaning issues for a major composite manufacturer when their customers could not get their composites clean. Eventually, we developed a proprietary, eco-responsible cleaner that safely resolved most common composite staining issues, especially those caused by mold! When composite owners started contacting us and asking "where can we purchase your cleaner", we formed Corte L.L.C. and named our cleaner Corte-Clean®, after the town of Corte Madera, California and began selling it. We would like to thank all the people & companies that have supported and encouraged our efforts and helped us to prove our product for safely, routinely, cleaning composites of all common staining issues.
