If chemical treatment or polishing is inadequate, Scotchbrite pads with water
might be a next step. They can be surprisingly abrasive on soft metals (they
can remove thin plating or anodising), so one wants to be gentle at first, but
they are less aggressive than steel wool or wire-brushing. I haven't heard of
any issues with them leaving embedded particles, as has been mentioned as a
problem with steel wool.
There are several different grades of Scotch Brite. The baby blue
grade, which is the gentlest, might be preferable to the green, red,
gray or other grades. That's all I remember of the grades but if you
find a box of the stuff, the grades should be described on it. Perhaps
the info is also on the 3M website somewhere?
