I was a bit worried about that one. There was so much oxidation on the brass -
and what looked like "pitting" on the surface, I just wasn't sure it would come
clean.

BTW, the metal cleaning product I use is "Noxon" - the manufacturer says it works
on 7 metals: stainless steel, aluminum, chrome, pewter, brass, bronze, and copper.
I've had very good luck with the stuff.
