Just a tip, Lemon Oil should not be used on a maple wood fretboard only on darker fretboards such as ebony or rosewood. Maple Fretboards are coated in a lacquer as a result the lemon oil will just sit on top of the fretboards and not absorb the lemon oil, it won't harm the guitar in anyway shape or form but just be a bit of a waste especially if you have a darker fretboard guitar somewhere else. A darker fretboard has no lacquer on it allowing it to absorb the oil keeping it nice and smooth ready to be played like a god.
