Banker Blended Fretboard Conditioning Oil
The fastest way to a fretboard with that smooth, broken in feel is proper conditioning. This is my own custom blend of pure lemon and rosewood oil that I use to give my fretboards that deep, rich color and worn in feel. It is commonly recommended to condition your fretboard a minimum of twice per year, however I like to use this oil blend on my own guitars every time I change strings. Dab some on a cotton cloth and rub it directly on to your fretboard, then wipe away any excess. Works great on bridges for acoustic guitars as well, and any other raw unfinished wood surface.
