1 paul pigat 4 weeks ago my guitars sometimes get neglected and go back in the case after being ridden hard. i've noticed a build up of tarnish on the hardware. Normally i would use Silvo to clean that stuff but i was concerned that it would take the gold off the hardware. Crest toothpaste works the treat!!!!! super shiny, no deterioration of the gold and it smells like mint now!!!!
