If I'm playing for more than 15 minutes, my hands will get a good bit on moisture on the fretboard. For my cheapy bass, I just wipe it down when I'm finished. But for my new Orion (ebony fretboard), do I need to do anything more as far as treatment/maintenance? I was concerned that the salt from the sweat might have some long-term affects on the ebony. I want to keep the bass in new condition forever...or as long as I can. Any input will be appreciated.
