Heat the oven to 150 degrees Fahrenheit and turn it off. If you have a gas oven, turn off the gas and the pilot light. Place a pot of boiling water on the bottom rack. On the top rack, put a heat-safe bowl or baking dish containing 1 cup of ammonia. Shut the oven door and leave it overnight.The next morning, open the oven and remove both the bowl of ammonia and the pot of water. Don’t dispose of the ammonia; you’ll want to use it later. Remove the racks and leave the oven door open to air out for 15 minutes. Add 1-2 teaspoons of liquid dish soap to the ammonia, along with a quart of warm water, and using a heavy-duty nylon scrubbing pad dipped in the ammonia mixture, begin to wipe away the softened grease and grime along the sides and bottom of the oven. It should be a fairly easy job at this point.
