Clean the interior and exterior using a light duty cleaner or soap and water with a rag to remove spills, stains. Using abrasive pads or harsh cleaners can wear off decal indicators which identify the knob controls.
Clean the interior of your oven three or four times per year. Spills and drips should be removed as soon as possible as they may smoke and/or catch afire.
Follow manufacturer’s instructions for self-cleaning ovens. Never use a cleaning solution to clean the interior of a self-cleaning oven unless it’s specifically made for self-cleaning ovens.
