Bare, I would get a second opinion as well. Can you spray it with clorox? That's my cure for all ills
. Seriously, I am a clorox freak. Did you look on the net to see if you can find a simple fix? Are you sure this guy isn't full of crap??
OK, I just looked. Seems clorox doesn't kill mold. I saw all sorts of things that do ,however.
