Toothpaste is designed to not only keep your teeth polished and clean, but to leave your breath minty fresh. Since the majority of the ingredients in toothpaste are designed to deodorize and freshen breath, there are myriad uses for the paste beyond brushing. The next time your hands are smelly from cutting onions or garlic, wash them with a squeeze of toothpaste. Add water, rub furiously and rinse off with soap. It'll neutralize the odors and leave your hands smelling fresh.
