Ozone
Bob, Steve, John and all... As I understand it Ozone (O3) is the primary cleaning agent in OxiClean. I believe that sail material has to be able to stand up to some of the harsh environments we put them in. Sun, rain, salt water, strong winds, rough handling all will take an eventual toll. Even mice and mud daubbers are a problem in some areas.And I never would have guessed that mildew might be a problem in the Okla. City area. However, your points are well taken and I enjoy hearing differing points of view.. Thanks to all. Jim Why knot!!
