fast-fret seems to make my strings rust faster, so i stopped using it...
don't mind me asking, what's string cleaner for?
usually my strings last like maybe 1.5 to 2 months then i just change them.
i have a bottle of string cleaner and it smells like nail polish remover. and i'm worried that cleaning it with string cleaner will be like fast fret i.e. make it rust faster...
