Thank you for all the imput on mildew prevention in a stored boat. I noticed that all of it dealt with absorbing excess moisture in the air. However, this does not deal with decks, fenders, material under tarps etc or when mildew has already started to happen. On plastics, of course, surface wildew is easy to remove with mild bleach treatment and/or cleaners. Once it penetrates deep down, as in vinyl seats or in white hypalon inflatable boats, I know of no chemical treatment that can both kill the mildew and removethe stain once deep penetration has occurred. The best thing is to prevent this from happening. How? Use our Cleanser/Conditioners, SEA GLOW for white and brightly colored plastics and CLEAR for beige, brown etc. These impregnate the plastic with anti-mildew (and anti-oxidant) conditioner. Then the surface is sealed to prevent penetration by mildew spores and to keep the conditioner in - this is done with SILKENSEAL. NOTE: actual test results can be seen on our website www.IslandGirlProducts.com under "uses, vinyl". What about carpet and soft fabrics? I use a shop vac and then microfiber cloth to soak up. You have to be VERY CAREFUL about the use on bleack on fabrics. On a mohair-type convertible top, I have used soap and water with very dilute bleach, then a dilute water emulsion of CLEAR to add a little anti-mildew to the fibers for future protection. I am also testing Lysol spray (that has anti-mildew properties) on all the soft fabrics. I'll let you know what happens with the car top and carpet! Thanks Jim Willis What about soft fabrics
