Just curious if anyone else has experienced this.
I use a Harbor Freight wet tumbler with SS pins (blue dish washing liquid, lemi shine, and water solution) to clean brass. Sorting some 9mm cases recently, I mistakenly included a steel case with one batch of my brass cases. After tumbling for about an hour, that batch of brass came out a pretty pinkish-copper color. All else seems normal, so I may just keep those cases for my daughter.
