I have this lemon oil spray thats used to clean the fretboard. It says to spray on a cloth first, but would it be safe to spray it directly onto the fretboard?

well, once you spray it directly on your fretboard, you'll have to wipe it off with something, so since you'll have a towel right there, why not just spray the towel first with it.

it just makes sense
