Don't forget after it's all cleaned up and newish again to disinfect her in some barbicide or high proof rubbing alcohol. Just to be safe. (Everclear works in a pinch)
brasso to clean it up. i havea couple of these. onse copper/chrome dual tone, and one chrome. brasso cleaned them both up to an awesome shine. one tipe with the handle is leave the brasso on for a few seconds, and then wipe it off. you can get brasso ay any grocery store or walmart. just look in the household cleaning section. they will be with the silver polish.
