An object surface is substantially cleaned by performing heating disinfection on a thin film at a high temperature in a state not contacting the object surface, and then covering and placing the thin film on the object surface. As another method, the object surface is cleaned by performing high-temperature heating on the object surface in a position retreated from its position of use, and then placing the object surface in the position of use again after cooling.
