PROBLEM TO BE SOLVED: To dispose of incineration ash without requiring cost so much and to restrain a generation quantity of waste after removal. SOLUTION: A dry ice grain is blown upon a cleaning object surface from an injection nozzle, and the dry ice grain injected from the injection nozzle collides with a sticking object sticking to a surface of the cleaning object surface, and is gradually collapsed from a tip part while pushing away the sticking object of the cleaning object surface by force in its collision. The tip part teras off the sticking object from the cleaning object surface by entering between the cleaning object surface and the sticking object by expanding in the radial direction. The dry ice grain suddenly changes to gas from a solid by its sublimation action, and tears off the sticking object around a collision part from the cleaning object surface by blowing away even the sticking object by the cubical expansion caused by vaporization, and the dry ice grain is finally completely vanished.
