Mold stains on unfinished interior wood trim
Dennis Racine

Anyone out there know how to remove mold stains from unfinished interior wood? Several years ago, I had new skylights installed on my home. I don't think the contractor insulated properly, resulting in a condensation moisture problem during the winter thaws on the interior wood trim of the skylights. (Since corrected with some spray-in foam. You'd think professional contractors could figure that out!) I think I've killed the mold with, last year, a 50:50 water & chlorine bleach solution and, this year, a 4:1 water to Borax solution. I'd like to get rid of the remaining mold stains (if possible) before I stain and polyurethane the wood trim around the skylights. If not, I guess I'll have to think in terms of a dark stain that will hide the mold stains and I really would like to avoid that.
