Expired baking soda, clean used aluminum foil and a little salt make an excellent silver cleaner.

Place your tarnished silver in an old pan (the pan will turn dark so you don’t want to use one of your good pans). Pour in enough water to cover silver. Add 1 teaspoon baking soda, 1 teaspoon salt and a crumbled up ball of aluminum foil. Bring to a boil and allow to boil for one minute. Remove silver, wash and dry with a soft cloth.
