Iso ONLY on vinyl.
Don't know what to use (regarding mold) on shellac coatings et cetera.
There was a recent thread in which care of the older materials used was addressed (not mold though) that I'll look for (think I posted to it).
Will do so later tonight, or tomorrow, as I have to get dinner going.
I've read about using UV light, but most non-commercial UV devices are not up to snuff from what I gather.
