Re: Removing zinc for another finish?
About 70% vinegar and 30% water overnight on new gold grade 8. I scrubbed one with red scotch bright, and left the other as is, which was discolored, so I had some doubt it would come out nice. Used Caldwell blackening (cold oxide) and sealant on both. The results are about equal and the black sticks, so no doubt black zinc will stick too.
