If it's what I'm thinking of, there may be a powdery clay in the mix. I guess trying the Isopropyl Alcohol can't hurt. I'll research more tomorrow. Otherwise, hello belt sander and/or grinder. It may be necessary to just put on a new surface on top of everything just to keep from breathing in whatever in dust form during allergy season and/or keep your sanity.
