Vinegar can be used to clean silver when it is mixed with baking soda. Vinegar is an inexpensive, weak form of acetic acid. It can be found in most homes, as it is frequently used in the kitchen. A small amount of vinegar is often sprinkled over green salad.
Silver tends to become dark and loses its luster when it is exposed to humid air. It takes a few minutes to prepare a solution of baking soda and vinegar at home. Silver jewelry can be brushed lightly after dipping it in this solution. The grime sticking to the silver dissolves and comes off.
