Wait until the oven is cool, and remove the crumbs and loose bits of burned foods found on the oven floor using a spatula.
Put on rubber gloves before working with ammonia. Pour about 2 cups of ammonia in a bowl. Use a sponge to apply the ammonia to the baked-on grease and stains inside the oven. Once they are wet, allow the solution to sit for at least 30 minutes.
Use a bowl of clean water and a fresh sponge to wash away the ammonia. Change the water frequently, and continue rinsing until you remove the ammonia and baked-on grease. Without a thorough rinse, the ammonia smell affects the food you cook in the oven.
Place a sheet of aluminum foil on the bottom of the oven to reduce the time required for cleaning in the future. Make sure any vents inside the oven are not covered. Check the owner's manual for the oven to determine if lining the shelf in aluminum foil is safe.
