It just adds life to your fretboard. Just use whenever you change strings or feel like frets are looking dirty. It cleans like a champ. You can even use to clean bridge parts and the tuners. It removes the oxidation from the surface. I even used it on the pickups and it cleaned the oxidation. But I would suggest to use it in low quantity. Just give it a try. You will love to see the results. Music nomad never disappoints.
