I wanted to share some good jewelry cleaning tips I've found online. This is a great list of 12 household products that can be used to clean any "gently worn" or tarnished jewelry bought at the thrift store or flea market.
Make your silverware — as well as your pure silver bracelets, rings, and other jewelry — shine like new by soaking them in a mixture of 1/2 cup white vinegar and 2 tablespoons baking soda for two to three hours. Rinse them under cold water and dry thoroughly with a soft cloth.
This one has a great reaction when you mix the ingredients! The shine is actually pretty impressive. This one started with a lot of metal chipping and gunk but now it's ready for the paint and tools!
