Do you cringe when you—or your guests– open the door of your microwave? A dirty oven is more than a kitchen eyesore. To cook food in an even, fast and energy efficient way in a microwave oven, those microwaves need to bounce around the inside of the oven. If there are dried food splatters dotting the oven’s inner walls, those microwaves can’t bounce. Instead, those food splatters get all the cooking impact and just get harder, while the oven is able to work less and less well. This chemical-free and easy way to clean will keep your valuable kitchen equipment at its best.
