I'll have to say that I find the powder idea intriguing...messy, but intriguing. My hands sometimes sweat when I play, which does cause corrosion, fretboard funk, and dead strings. Many years ago I used a powder that I applied directly to my left hand, it seemed to help a little.
Using powder would not have to be an exclusive treatment - there is no reason why a fret board could still not be oiled periodically, like when strings are changed. I wonder though, would the powder tend to wick the lemon oil or whatever out of he fb...?
