Best way to clean fretboard?

Great guide slickstring. Being a woodworker I would agree with that one hundred percent. My guitar has a Maple fretboard and it is already treated so I just clean it. I don't use heavy oils or much of it because it can tend to gum up when it gets damp or humid and then you end up with a build up of dust. Best to use as little product as you can and it is healthier for the wood.
