Unclenick, I found your statement interesting :

To check for damage, after the ultrasonic cleaning I subsequently polished it in treated corncob and all the pink turned into polished brass.
Some of my brass is pink going into the tumbler and pink coming out. The sst pins and Lemishine just make the brass clean and shiny, but no change in color.
