If you search the archives, you can find a post that has a recipe for brass cleaning solution. I can't recall the author just now, but I have it printed out at work. The subject of the post is something like this: fabulous brass tarnish remover. It consists of warm water, chromic acid and an alkaline buffer (can't remember exactly). Brain fag... Anyway, 10 seconds in this soup, and your corrosion is history. And, you won't burn your hands in the stuff (wear gloves anyway! It will stain anything a yellow color). If you leave things in it long enough, they'll disappear. You won't know how you did without it.
