I've been buidling a vivarium, but I didn't seal this piece of wood before I permantly foamed it to the background. This wood deals with constant running water, misters, fogs, and its been creating mold. Is der anyway to permantly remove the mold. I can't use any toxic substance, due to living habitats created for Dart Frogs, but I've been putting my frogs in quaritine, and I really want to move themi into the vivarium.
