a while ago i got a guitar cleaning cream to clean my guitar, but i never used it. now I have a new guitar , (gibson lp studio) and it needs to be cleaned badly, so i was looking at the bottle and it says 'safe on all common finishes". I'm guessing my LP finish is "common", but I just want to make sure.
Strip your guitar down, poor nitromorse all over it and scrape the finish off. Sand it for two days, then oil it. Thats what I'd do ! You'll probably just wanna clean it though so Id just try a little on the back or in the cut away just to see what happen's.
