Line a baking pan with silver foil. Add enough vinegar to a pot that will fill your pan 1-2″ deep. Bring the vinegar almost to a boil then add 1 TB of baking soda. Pour the solution into the pan and add silverware. The solution will cause the tarnish on the silverware to transfer to the foil. Remove clean pieces. Rinse with cool water and pat dry.
