There are several easy approaches to doing this - if they are just
cruddy, the stainless will clean right up.

1) a reloader will have a walnut shell vibrating tumbler that would
clean them right up.

2) the deposits are either a varnish of old smoke goo, which some
solvents will readily remove, or a deposit of other
dirt/gunk/corrosion... a pass with several solvents should clean it
off - put the hardware in a tin can, fill with something you want to
try, shake then see what it does.  End up with using a bathroom rust
and stain remover, and it should cover all the possible stuff on it...

3) if the hardware is physically mangled, then by all means replace it

The stainless steel cleans up really really well, and is a lot cheaper
to do it this way.  I didn't mention it before because I thought it
was chewed up.
