Cleaning Oven Interior
All ovens should be cleaned frequently with hot, soapy water. 
Non self-cleaning ovens
Oven door: For non self-cleaning ovens, use Oven Mate Cleaner. Apply oven cleaner with a damp sponge.(Tips from professional cleaners in Cambridge)
Oven racks and rack supports: Clean with hot, soapy water or use soft scrub cleanser. Remove before self-cleaning.
Oven interior surfaces: Use Oven Mate Cleaner. Follow manufacturer’s directions. For self-cleaning ovens,
remove oven racks and rack supports and follow self-clean instructions in the Use and Care Manual.
Never line the oven cavity with aluminum foil. It will melt on and permanently damage the surface.
Self-cleaning ovens
Oven interior surfaces: Remove oven racks and rack supports (Some types only) and follow self-cleaning instructions in the Use and
Care Manual.
The infrared broiler should never be cleaned. Any cleaner can damage the special mesh screen and/or the igniter.
This cleans most efficiently while still hot.
Roast & Rack Grills:
May be cleaned immediately after cooking is complete and before turning off the flame. Use a soft bristle brush to scrub the grill racks. Dip the brush frequently into a bowl of water. Steam is created as the water contacts the hot grate. The steam assists the cleaning process by softening the food particles. For thorough cleaning of the grill racks, use grill cleaner according to manufacturer’s directions and then soak 15 to 20 minutes in a hot water and mild detergent solution. After soaking, scrub with a blue scotch-brite pad. Do not use a steel wool pad or abrasive cleaners, for risk of damaging the porcelain finish. Dry thoroughly.
Oven trays:
Scrape off all burned on debris. Soak 15-20 minutes in a hot water and mild detergent solution. After soaking, scrub with a green scotch-brite pad. Oven trays can be also safe washed using a dishwasher.
