Is your silverware looking a bit dull these days?
Try an ion exchange, a molecular reaction in which aluminum acts as a catalyst. All you have to do is line a pan with a sheet of aluminum foil, fill it with cold water, and add two teaspoons of salt.
Drop your tarnished silverware into the solution, let it sit for two to three minutes, then rinse off and dry.
