Since no one seems to wanna go along with my idea of leaving the tarnish in place, here's my advice if you must clean it up...anything that takes the tarnish off is gonna do some small damage to the surface of the metal, but nothing major unless you leave it on for a prolonged period...to reduce the elbow grease involved, a buffer would be good, if you can get your hands on an electric drill (preferrably cordless) there are buffing padsthat fit right into the chuck...ask any guys you know, most have at least one drill, & wouldn't mind loaning it out to a "damsel in distress" (esp if they think it imploves their chance of getting some ). for tight corners & any fine detail parts, a Dreml or other rotary tool also have small buffers that come in real handy. I've cleaned up some silver & brass objects for sale on Ebay using the above mentioned tools & rubbing compound (also known as jeweler's rouge) with good results...just go easy & don't rub excessively in one spot, after all your goal is to take off just a very thin layer of oxidized metal & nothing more...
