A:Answer Hi Ann - Thanks for viewing GE Model PS960SLSS! Both ovens feature Self-Clean with Steam Clean Option so you can choose how you want to clean your oven. Self-clean is cleaned by heat, at temperatures above normal cooking temperatures. During the cleaning cycle the oven is heated to about 880 degrees Fahrenheit (471° C.). At this temperature, food soils inside the oven decompose, leaving behind a small amount of ash. The leftover ash is similar to cigarette ashes, and wipes out easily with a wet cloth. The cycle can be 3 hours or more. Steam Clean allows for quick cleaning of minor food spills at temperatures lower than the standard self-clean feature. Simply pour 1 cup of water into the bottom of a cool oven. Close the door and select Steam Clean. The cycle lasts about 30 minutes, and loosens and softens the grime in the oven. Once the cycle is complete, wipe out the moisture and food soils with a soft cloth. Keep in touch at GEAppliances.com. Sue
