" How do you clean an oven with ammonia? Do you heat it first or do it in a cold oven? -- Shirley DO NOT HEAT THE OVEN! Simply place a small bowl of nonsudsy ammonia on a cookie sheet and put it in the oven overnight. The fumes will help soften the gunk on the oven walls and floor. But be careful when opening the door -- the fumes may be strong. "^^<http://www.w3.org/2001/XMLSchema#string>
