FYI From beading Daily. This does really work!
Tarnish-Busting Formula
1. Choose a plastic or glass (never metal) pan that is deep enough so that when filled with water your tarnished jewelry will be covered.
2. Put a piece of aluminum foil in the bottom of the pan.
3. Pour near-boiling water into the pan.
4. Add a couple tablespoons of baking soda to the water.
5. Place the tarnished jewelry onto the piece of aluminum.
6. If necessary, add more baking soda to the dish until you see the tarnish coming off your piece. You should get a slight bubbling effect with an odd odor.
For a fast clean up, I use tooth paste- put a little on your thumb and pointer finger and rub it in the silver, rinse, dry with a paper towel and go!
