Out of silver polish? In a pinch? You can use white toothpaste to clean the tarnish off your silver instead! Just run the silver under warm water and work the paste into a foam and then rinse it off. Since the toothpaste is more abrasive than polish, a little goes a long way — you don't need to use much. And, if there are any stubborn black spots in nooks and crannies, you can actually use a toothbrush (an old one) to get rid of them.
