Your oven’s auto clean (or self clean) is a great feature, if you use it properly. Set a regular cleaning schedule for your oven, so there is no heavy build up of grease and debris. This is a potential fire hazard. Wipe any loose debris away before setting your oven to auto clean. Also while in the auto clean mode, use proper ventilation by opening a window and turning on the exhaust fan. And NEVER EVER leave the apartment while your oven is in the auto clean mode. Actually never leave your apartment while your oven is turned on, whether it is cleaning or cooking.
