I wipe mine down with an old soft sock after gigs, and then use a bit of Sadowsky guitar polish just to clear off any sweat residue. I'll use some Fret Doctor oil on the ebony fingerboard in a few months - it worked great on my Lull. I think the only real worry is fingerboards drying out and cracking. As for the body, if I get discoloration from playing - all the better.
