PROBLEM TO BE SOLVED: To provide a cleaning method which (1) can save water markedly and can reduce the amount of a detergent to be used or can eliminate the use of the detergent, (2) has a high effect on cleaning complex fouling with strong adhesive force, (3) is economical and simple, and (4) can correspond to HACCP, and an apparatus for the method. SOLUTION: In the cleaning method, water around the fouling 9 adhered to an object S to be cleaned is removed, the fouling 9 is frozen by using water contained in the fouling 9, the temperature of the frozen fouling 9 is changed sharply by hot water W the temperature of which is different from that of the fouling 9, and the fouling 9 is removed from the object S. The cleaning apparatus is composed of a means 1 which sprays air to the object S and removes water around the fouling adhered to the object S, a cooling gas ejection means 4 for drying/freezing the fouling 9, and a hot water-cleaning means 2 which changes the temperature of the dried/frozen fouling 9 sharply and separates/removes the fouling 9 from the object S.
