Prevents Silver from Tarnishing
Well, it is indeed very annoying when you keep something for such a long time and you thought that it would be safe when taking it out after years. Aluminum foil, our dearest friend so far, deters washed silver from tarnishing.
Now, Whenever you need to store silverware for a long time, first wrap them in cellophane and wrap them in a foil sealing the edges. Next time, when you open the stuff you wrapped, you will be grateful with your past self.
