Whirlpool ovens usually come with either a self-cleaning option or a steam-cleaning option. Either option requires removing everything from the oven, wiping up debris and pressing the specific cleaning setting.
The self-cleaning option works by heating the inside of the oven to higher-than-baking temperatures. This burns away any mess inside without the use of chemicals. Since the front of the oven and door do not get hot during this process, it is necessary to clean them with a mild dish detergent and sponge. Be sure not to disturb the gasket around the oven door. Seal the door and select the self-clean option. This cycle requires a full 12 hours to complete. Once complete, take a sponge to the interior and remove any leftover debris.
The steam-cleaning option requires that 4 ounces of distilled water to be added to the bottom of the oven prior to shutting the door. Distilled water is preferred because it does not leave mineral deposits on the oven's surface. Select the steam-cleaning cycle; a beep sounds after approximately 20 minutes. At the end of the cycle, remaining water should be removed with either a sponge or cleaning cloth. If stubborn spots remain, a non-scratch copper scrubbing pad may be used to remove them.
