Sly, here's what I do, I put a few drops of lemon oil on a cloth, and wipe a wet coating across the fretboard, leave it set for a few minutes and then wipe off whatever is left on the fretboard. Since the climate there has fairly low humidity, I would start off by using the lemon oil every other month, if you notice that it soaks right in after a few minutes and there is very little to none left to wipe off, then increase the frequency. Lemon Oil does dry, if you think you have used too much, just don't use any for a while, if you ever notice the fretboard "sweating" up any oil after playing, that's a good sign that you are using too much, too often. Good Luck..................
