Silver tarnishes because it reacts with the small amounts of smelly hydrogen sulfide, H2S, we put into the air as we digest our food. In this reaction, the silver loses electrons to the sulfur. You can reverse this reaction by allowing the silver to get its electrons back from aluminum. Flatten some aluminum foil on the bottom of a cooking pot.
