Muriatic acid will cut through severe tarnish and heavily accumulated crud on brass instantly on contact without damaging the brass. Wash the part(s) thoroughly with water to neutralize and remove the acid. It (the acid) will leave the brass a funny pink color, but your favorite metal polish (Brasso, Flitz, etc) and the usual amount of elbow grease will take that right off.
Be really careful with the muriatic acid, though, as it´s strong stuff; incidental drips, splashes, etc., can permanently mark various other surfaces. I haven´t had any problems with it touching my skin for a while, but a person with very fair skin might have some reaction.
