It...Really....Works! I tried it last night, with tartar control from both colgate and crest, and my only complaint is that it stays a little sticky.
Instructions (FRONT):
1. Take soft cloth and add a tiny ammount of toothpaste that barely rises above the cloth.
2. Rub the toothpaste up and down over the surface of the ipod, you don't need to use too much force. (add more toothpaste if it doesnt cover the whole area you're trying to cover.)
3. Before you buff off the toothpaste you need to get it a little moist...lick the tip of your finger :) and rub over the toothpasted ipod.
4. Buff off the toothpaste in an up-and-down motion to prevent swirls.

**toothpaste also works in the same way on the back**
Good Luck!
