A method of removing oil and/or grease from a part having a baked-on oil and/or grease deposit thereon, comprising the steps of causing substantially the entire surface of the part to be in intimate contact with water within a pressure vessel, heating the water in the vessel to a temperature of at least about 450°F. and under sufficient pressure to prevent boiling of the water for a period of time sufficient to decompose the deposit and convert the deposit into a composition which can be removed by a low hazard solvent, causing the part to be out of contact with said water, subsequently causing substantially the entire surface of the part to be in intimate contact with a low hazard solvent for a sufficient time to dissolve the decomposed composition, and then causing the part to be out of contact with said solvent.
