A few of the many things you probably didn’t know toothpaste can be used for: cleaning jewelry, repairing scratched CDs, cleaning headlights, relieving itching from bug bites and styling your hair. Best of all, most of the uses are incredibly simple. For example, to repair a scratched CD or DVD, just rub the toothpaste on and then gently rub it off with a clean, soft cloth. To clean your headlight, mix the paste with a bit of warm water and use a buffing pad to clean your light.
