A:Answer Hi Hayward- This model has self-clean with optional steam clean so you can choose how you want to clean your oven based on soil level. The self-clean cycle can generally be programmed from 3-5 hours and 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. 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. Thanks for considering GE Profile Model # JTD3000SNSS. We’d love to have you in the family! Sue
