Restore luster and shine to your fingerboard.
Lemon oil (a light mineral oil) is used to clean and condition fingerboards. Just a little bit about twice a year will prevent unfinished wood from drying out and cracking.
Lemon oil is safe for all woods, frets and inlays. It will penetrate and deepen the rich color of unfinished wood, and will clean dirt and grime from a finished board.
