Dirt, including soap scum and moisture are key ingredients for mold, the others being still air, warmth and darkness or shade which are conveniently provided by boat covers. The removal of one or more of these ingredients will prohibit the formation and growth of mold and their associated stains and health hazards.
Boat covers can be safely and thoroughly cleaned with free rinsing FABRI-KLEAN fabric cleaner and waterproofed with CANVAS SHIELD water proof spray. FABRI-KLEAN will not leave a soap residue. CANVAS SHIELD will not support mold growth and because of its deep penetrating power, it encapsulates and protects the underside of the threads in the fabric as well as the exterior side, giving it better protection.
Mold spores are ever present in the air. When they land on a suitable host they rapidly grow and multiply. The visible mold that you see and even wipe away is the bloom, like the flower of a dandelion. You can remove it but unless you remove the root or inhibit it from growing, it will continue to grow and the root will burrow deeper and become stronger and more tenacious. The bloom releases spores into the surrounding air to propagate more mold and the root continues to devour the material under the surface. It’s this degradation under the surface that gives the indelible mold stains visible on vinyl seats, inflatable boats and synthetic fabric boat tops and cushions. Removal of the mold stains usually causes even more damage to the substrate.
Regular cleaning with free rinsing FABRI-KLEAN and annual re-application of CANVAS SHIELD plus proper ventilation under the boat cover can easily double or even triple the life of your boat canvas.
