Re: How often do you burnish your frets?
Burnishing is more akin to shinys, you aren't reshaping the fret wire like when you crown one. I use extra fine steel wool. My buddy used to have a furniture polish that cleaned the fingerboard, AND the frets, I don't know what it was, and he said they quit making it.
Anyways just use something to mask the fret board and you'll be all right, your guitar will play much different after a burnish, and oiling.
