Any suggestions for things to clean a finished maple board?

Ty

Breath on it and wipe it off with a soft clean rag.

1, no problems using a bit of warm water a light detergent (soap) as well, assuming the back is also finished

Fast Fret?

Have you used Fast Fret as a fretboard cleaner before? Does it work well?

I use Fast Fret, but only as a string cleaner/lubricant, and it works well for that. I've never bothered to stick that big stick into the fretboard.

Well, I've used it on my rosewood fretboard, and it seems to make it nice. I generally give the wood between the frets a wipe with it when I'm changing strings and I have a bare neck in front of me; it certainly isn't gonna cause any harm, that's for sure.

Or you can use some Naphtha (zippo lighter fluid). I use it for every bit of cleaning my guitars, and it does wonders. I use it with a planet waves soft rag thing. One of those microfiber ones. Know what Iquot;m talkin about?
