I want to know how best to clean up my guitar. Most specifically, the fretboard. I've read (I think) that getting moisture into the fretboard is bad because the wood will expand.
So what can I/should I use to clean the fretboard? How often? Should I take all strings off to do it, or is it bad to have no tension on the neck?
Also, is there anything I can use to rub the metallic parts with to clean them up? The bridge gets a gradual buildup on it from muting.
