How should microwave ovens be cleaned?
Clean the oven cavity, the outer edge of the cavity, and the door with water and a mild detergent. A special microwave oven cleaner is not necessary. Do not use scouring pads, steel wool, or other abrasives. Source: U.S. Food and Drug Administration, Center for Devices and Radiological Health Consumer Information.
