Maybe a superfine brass one on a bench grinder for the outside diameter corrosion. For the internal corrosion maybe a fine brush on a dremel. I tend to shy away from using wire brushes on dremels for several reasons: 1) they're really little and individual wires start breaking off and flying everywhere pretty quickly 2) they get ruined in like the first minute when the rotation of the dremel makes them bend back away from the rotation of the Dremel. I guess if Dremel or one of their competitors would realize that what is needed it a
REVERSE setting on one of these things to balance out the wear. 3) they cost like $5 each - not at all cost effective.
