Oil quenched works are immersed in water at a temperature of 75.degree. C. while the works are maintained at a temperature of not lower than 100.degree. C. In the step of immersing the works in water, the water boils on the surfaces of the works to remove most quenching oil from the surface of the works. A part of oil removed from the works is caused to overflow from the upper portion of a water bath and exhausted therefrom. In the step of immersing the works in water, the works are retained at a temperature suited for an alkaline cleaner. After having been taken out of the water, the works are cleaned in a step of showering water. A step of immersing the works in the alkaline cleaner is performed before the temperature of the works becomes lower than 60.degree.C. The alkaline cleaner used in the step of immersing the works in the alkaline cleaner is maintained at a temperature of 70.degree. C..+-.5.degree. C. In this range of the temperature, quenching oil is continuously removed stably for a long time. The works are cleaned by water in a final washing step performed after the step of immersing the works in the alkaline cleaner. Thereafter, the works are dried by hot air in a drying step.
