There are plenty of copper cleaners on the market that might give the
desired results with a little care and an acid brush or q-tip.
Never Dull might be the best bet. It's cotton balls that are doped
with a copper cleaning solvent. Can be gotten at any hardware or
marine supply shop. Should be safe for any of the components and
they're water free.

Trouble is you can't guarantee they won't leave some form of coating on
the copper that isn't good for soldering. After all, they're not made for
this job.

I favour mechanical cleaning. Fine wire wool or like I said a fibreglass
pencil which is made for the job.
