1 piece aluminum foil (big enough to cover the bottom of the cleaning container)
1 to 2 tablespoons baking soda
2 quarts very hot water
Lay the aluminum foil along the bottom of a plastic or glass container.
Place the tarnished silver on top.
Sprinkle the silver with baking soda, and cover it with very hot water.
Soak until bubbles stop, then rinse and polish the silver with a soft cloth.
