Need to polish some jewelry? Put toothpaste on it!

I'm going to let you in on a little secret.  Shhhhh! Do you need to polish up some of your silver jewelry but don't a) know how b) don't want to go buy special jewelry cleaner or c) both?  Just put some toothpaste on it. Scrub scrub scrub and Voila!

As you see in the picture I used a q-tip, but the best option is an old toothbrush since it's the easiest to scrub with.  I've also used a washcloth, paper towel, and pretty much anything you can scrub with. Amazing. Easy. Cheap. Super Secret.
