No solvents, really, since what you are looking at is corrosion/oxidation 
(copper oxide is black or red, depending on the form).

Various forms of "bright dip" are available... usually consisting of some 
mixture of nitric and hydrochloric acid.

Flux for soldering essentially produces the same effect, with a heat 
activated chemical reaction (Ammonium Chloride (Sal Ammoniac) and Zinc 
Chloride (Tinner's fluid) being notable examples).  The brush on tinner's 
fluid is actually a mixture of hydrochloric acid and zinc chloride, 
historically made by dissolving some zinc in HCl (but not enough Zn to 
totally react with all the acid)..


If you don't want to fool with corrosive acids, one of the commercial brass 
polishes might work (they use a combination of ammoniacal compounds and a 
fine abrasive), but watch out for a film that they often leave behind (to 
prevent tarnishing).
