Cleaning silver with baking soda is a popular and effective method. You can create a paste by mixing baking soda with water, or use the aluminum foil method: line a bowl with foil, add baking soda and hot water, and soak the silver. The tarnish will transfer to the foil. Have you tried cleaning silver this way before? If not, what items are you planning to clean? It can be quite satisfying to see the shine return!
