Baking soda,salt and aluminium foil create a chemical reaction that removes tarnish from silver without any harsh chemicals or elbow grease.
Be careful while pouring baking soda, it will froth. Its important for the aluminium foil to touch the silver, otherwise its not going to work. An alternate way is to use a large aluminium pan, place the silver and salt in it and pour boiling hot water on the silver.All items to be cleaned,need to lay flat on the Aluminum pan,in other words,everything needs to touch the aluminum.
