A:Answer The walls on the inside of the oven feature a non-stick coating for easy cleaning. To clean any splattering that may occur while cooking, wipe the walls with a soft, damp sponge. A nonabrasive liquid cleanser or mild spray solution may be used to avoid build-up of stains. Apply the cleanser to the sponge, not the oven surface, before cleaning. Avoid touching the quartz heating elements.
