Nevr-Dull Magic Wadding.

Great on chrome! Never tried it on brass.

I was outta the AF by time I discovered Nevr-Dull, so tried to avoid
brass like the plague. I usta weld/sil-solder brass/copper, but we
always had nitric acid(?) dip tanks to chemically clean both. This at
a govt lab.

Hmmmm.... I gotta all brass pepper grinder I can try my old can of
Nevr-Dull, on. The can may be TOO old. The wadding tends to dry out,
after a few yrs.
