All of you are addressing the killing of the mold. Mold spores are everywhere. They hide in the fabric
and fissures of the spaces around you. They float in with the air. Killing them is only one side of the discussion. What makes them keep coming back is that they have access to MOISTURE. Reduce the moisture and they cannot flourish. The calcium chloride knockoffs (Damp Rid, etc.) merely suck water
out of the air and collect it in a bowl. We live in an environment
that sits in water
. You are simply wasting time and money
and hope in trying to eliminate moisture with chemicals. It is far simpler and effective to reduce moisture through the circulation of outside air flowing through the boat and the higher humidity inside. Make an active pathway for air circulation using open ports
or dorades OF SUFFICIENT CAPACITY to allow passing breezes to sweep through the boat. Use fans to SUCK the air out of the aft end of an anchored boat, or the downwind portion of a docked boat. Make an inlet of fresh, outside air at the windward part of the boat. Move lots of air and you won't need to wash with vinegar, use hygroscopic chemicals to suck up excess moisture, or suffer the irritating odors of Lysol, vinegar, etc. Eliminate the excess moisture and eliminate the mold that grows because water's available.
Sabray, you forget that we shed skin cells, bacteria, hair, that breezes carry dust, that critters too small to see are living and dying around us and their residues are collecting on every available surface. That makes food
for the mildew spores, who then need only water, collected from the air, to survive and prosper. Nobody keeps their boat so clean as to be sterile.
