ok all you MJ fanatics - I need some help. As some of you know, I am FINALLY cleaning out my closets and I was looking at my old MJ bag and was really saddened to see that all the hardware has a really brassy kind of tarnish going on. I only have this one MJ so I don't know much about it, and it is totally worn from a couple of years ago so taking it back is way out of the question. Will it polish off if I take it to the cleaners or is there something that you use to get it to be shiny again? THANKS!
