Put your tarnished jewlelry in a bowl with some warm water, salt and baking soda that will clean the spots off without the hassle of hand-polishing.
I am going to try this one. I don't think I have baking soda, I.. My jewelry is not cheap, cheap but not excessively expensive either (some pieces) I love my pieces and wanted to know how to keep them protected..
I have also heard you keep your jewelry in plastic zip-loc bag that keeps away the air and elements of tarnishing..
If anyone know of any other idea, please share..
