Best cleaner IMHO. Takes care of all the finishes, but just don't apply directly on nitro cracks or old-worn surfaces. Regarding my guitars, it works perfectly for both urethane Fender finishes (body and thin urethane neck finish) and nitro Gibson finishes (as I said, avoid cracks, because it can cause clouding). Non abrasive, no polish, just soft cleaner. Smells great, also
