mica suggested, and who wouldn't follow her advice, that i purchase 100% pure, organic lemon oil to keep my fretboards in top shape, and to bring dried out fretboards back to life. i went to a health food store and found the pure, unadulterated stuff w/o any problem. my other alembics were older and the oval inlays had some wear and discoloring, a patina if you will, to them. my new mark king possesses absolutely clean, bright, pristine oval markers. so, if and when i oil my fretboard, does any care need to be taken to avoid getting the oil on the oval fret marker inlays? will they discolor or can the oil get in behind the inlays and discolor them or cause other problems w/them? are the inlays somehow sealed so there would be no problems? anyone know? mica? val?
