For cleaning tarnish you have to heat 2 cups of water and add 2 tablespoons of baking soda and then put the silverware on aluminum foil.Make sure they are in contact in a pan having these things. Later heat will cause tarnish to vanish. For further assistance please visit this link.
Cover the bottom of the pan with aluminum foil . Put your silver on the foil - it should touch aluminum.
Boil water, remove it from the stove and place in the sink. Add 200 g of soda to 4 liters of water in boiling water. The mixture will foam a little, so we put the pan in the sink.
