Will Barkeepers Friend get it off? I’d deffo have to polish up that sucker...it’s a beautiful cymbal underneath the crud!Yep, but my thinking is, it was a dry ride when new, so I'm confident in it staying dry even after a good polishing. Besides, I doubt my ear could differentiate. Age and hearing damage have made me less picky about such nuances. Patina reflects neglect, in my OC(P)D mind. That alone decides it.
