To make homemade silver polish, gather a quart of hot water, a tablespoon of baking soda, a sheet of aluminum foil and a non-aluminum dish. Using this polish on silver with raised designs or with pieces with cement may damage the item.
To begin, line the bottom of the non-aluminum dish with the sheet of aluminum foil and place the silver items in the dish. Mix the tablespoon of baking soda with the quart of hot water, and pour the solution over the silver. Allow the silver to soak for a minimum of 30 minutes. Time may vary depending on the level of tarnish on the silver. Remove each piece, and buff it with a dry, clean cloth to polish.
When polishing silver, always use cotton gloves, not rubber ones, as rubber can cause the silver to tarnish quickly, and the gloves may leave fingerprints. Don't place rubber bands on the silver, as they may stain the metal. After washing the silver, place the pieces on a cloth or paper towel. When storing the silver, make sure the drawer has a flannel, cotton or felt mat. If tarnish appears quickly following polishing or if there are stains that do not come off, contact a silversmith for more options.
