Aluminum foil is a poor solution. The soft foil actual fills the pits when you rub it over the chrome. The problem is, it doesn't actually remove any rust, which still eating away at the metal under the foil. However, it does improve the looks with little effort. It's a quick and dirty flipper's trick, but not in the same league as the other solutions mentioned.
