My latest purchase is a 94 MIM P bass. I am in the midst of upgrading it with Hipshot tuners, Gotoh bridge and EMG pickups. My other basses have or have had maple fingerboards. The fingerboard on this one is rosewood. It is pretty filthy. I have read that lemon oil is good to use to clean and protect it. I have actual 100% lemon oil not the furniture type of lemon oil. Is this o.k. to use to clean and protect the fingerboard?
