Denatured is what we always used to clean tape player/recorder heads. Isopropyl had something in it that left a film on the head that was not good for the tape or the music transfer, can't remember. I "think" denatured is what you would use with wood, not the Isopropyl, but let's let the mor knowledgeable ones on the matter answer that. Jim.
