Unsightly rust rings on your bathroom counter? Those are a pain to scrub! The trick to get rid of the rings without much effort is to reach for your toothpaste. Just squeeze a dime-size dollop of non-gel toothpaste onto a wet washcloth and rub it onto the rings in a circular motion, then rinse clean. You may also sprinkle baking soda for extra power. The toothpaste will gently buff away rust, leaving your counter top spotless.
