2Tested by both The Kitchn and Apartment Therapy, this two-ingredient trick will leave your tub sparkling. To start, grab that bottle of Dawn (or any other dish soap) from your kitchen sink and the broom stowed away in your closet. Dish soap is designed to cut through tough grease and food stains on our delicate dishware, but it will also disintegrate the dirty marks and soap scum lining your tub.
