cleaning up cruddy geared tuners
How would you suggest cleaning up nice geared tuners that were stored for so long a bit of crud has accumulated on the surface?
I recently acquired a dulcimer that was stored in its case for probably a couple of decades. It has nice gold Grover tuners, but a bit of crud subverts their shine. Are there specific products that would work? My wife has some stuff she uses to polish jewelry. Should I just use that?
