The exterior of the conveyor oven must be cleaned daily. While the oven is still hot dampen a towel or grill pad with plain water or detergent and water and wipe down entire ex- terior of oven including the back and fan covers. Grease can build up on the top of the oven openings and the area above the windows. If this buildup does not steam off with a damp towel dip the towel in filter powder and rub lightly. Clean exte- rior any time at the end of each night, even before the oven has been turned off.
