Technique #1: Rub silver with a soft cloth and a paste of baking soda and water.
Technique #2: Rub silver with a soft cloth and toothpaste.
Technique #3: Place a sheet of aluminum foil in the bottom of a pan, add 2-3 inches of water, 1 teaspoon baking soda, 1 teaspoon salt, and bring to a boil. Add silver pieces; boil 2-3 minutes, making sure the water covers the silver pieces. Remove silver, rinse, dry, and buff with a soft cloth. This method cleans the design and crevices of silver pieces. Not recommended for pieces that have glue.
Alternative versions of #3 do not require boiling, just letting the silver sit for five minutes.
