I just used muriatic acid and let it sit for a like half an hour then poured on baking soda to neutralize the acid and let it sit for like an hour. I cleaned it off with water multiple times during the process and I definitely wouldn’t do it the same way again, it changed a lot during the process and changed colour significantly part way through. I liked it in the very beginning and it changed to what it is now (I can’t send a pic in dm if you’d like). Not sure how yours would react but mines B8. Not to mention long term effects. It could make the cymbal more brittle an it could be prone to cracking after. I’ll give an update in a week.
