Does anyone have any good tips for cleaning base metals? When I first started making jewelry, I admit I did not know what I was doing :) The clasps and even some of the metal beads I used discolor and have an awful smell after cleaning them. I've made (and sold) items with some of the metals (either in beads or clasps) and feel horrible that I used metals with such an awful scent! I've used vinegar on some of my own jewelry, but found it doesn't work well with leather cord (like the wrap bracelets). Polishing with a jewelry cloth removed the discolored part, but not the scent.
