Tarnished brass

[sparxs.livejournal.com]

I have some brass craft rings that I am trying to tarnish to an antique brass look. I went through the memories and found an article on copper but nothing for brass. Possibly the same solutions work for both but I wanted to see if anyone has any good household ideas specifically for brass. I have been using Drano which seems to be doing the trick but it is going slowly and the rings are not entirely consistant. Is there also anyway to dull/break down stainless steel? "Stainless" is the problem. ;) Thanks for your suggestions and ideas!
