The glass on oven doors needs to be cleaned with a non-abrasive cleaner that dissolves grease. Abrasive cleaners or pads can make fine scratches on the surface of the glass that cannot be removed.
Cooking causes grease and oil particles to stick to oven surfaces as a residue or film that can be difficult to clean. The grease must be broken down to be removed. Grease-cutting cleaning agents, such as Cameo, Dawn Power Dissolver, and Mr. Clean Magic Eraser, are effective in dissolving grease on cooking surfaces. Glass oven doors should be cleaned with a soft cloth to avoid scratching the surface.
