You can remove oxidation from silver quickly and easily using this simple technique. You need baking soda, salt, boiling water and enough aluminum foil to cover the bottom of a glass baking pan that is large enough for your silver. This takes 15 minutes.
- Prepare the solution
Line the bottom of your pan with aluminum foil. Bring enough water to cover the silver to a boil, and pour it into the pan. Add a teaspoon each of salt and baking soda. You can scale this recipe up or down as your need requires.
- Place the silverware in the solution a piece at a time
Place each piece of silverware in the solution, and confirm that each piece touches the foil as you drop it in. Leave heavily tarnished items in the solution for up to 5 minutes. Remove the silver when it's clean, rinse it with water, and dry it with a soft cloth.
- Clean jewelry by placing it in the bowl first
Line the bottom of a small glass bowl with foil. Carefully position your jewelry so that it has maximal contact with the foil. Use 1/4 teaspoon each of salt and baking soda. Turn your pieces over, and repeat as necessary. Rinse your clean jewelry with water, and buff it dry.
