My fretboard is horribly dirty. I should clean it with lemon oil, apparently (it's rosewood by the way). Just a question: I have this wood polish that's orange based. I'm just wondering if someone has encountered a product like this (which is really amazing on woods like maple) and how it would react to a rosewood fretboard. I'm guessing it should work, it's similar to lemon oil. Thanks. PS, can someone recommend a brand of lemon oil to make sure I'm using the right product? Thanks.
