What can I use to clean rust off my guitar strings?
Unfortunately, speaking as a fellow musician, nothing. The best thing to do is to replace them and if you play very often, wipe the strings down with a soft cloth afterwards.
Umm i think its time to buy new strings :3
Try WD40. You'd be better off just buying new strings.
if you have rust i know you should get new strings if one gets rusted to much it could snap and while you are playing it,it will smack you in the face and is very dangerous.it can take out you eye realy easy and cut you right open.
