<p>A self-washing step of rotating elastic polishing members 230, supplying a liquid L to the elastic polishing members 230, and, in this condition, pressing pressing units 220 against the elastic polishing members 230 to deform the elastic polishing members 230, thereby washing the elastic polishing members 230 themselves is added to a scrubbing step of rotating lens molds 1, 2, rotating the elastic polishing members 230, pressing the elastic polishing members 230 against the surfaces of the lens molds, and, in this condition, supplying the liquid to the areas between the surfaces of the lens molds 1, 2 and the elastic polishing members 230, thereby washing the lens molds 1, 2. In a drying step, hot water is supplied to the lens molds 1, 2 being rotated, and thereafter dry air is supplied thereto. <??>It is possible to securely remove foreign matter and dirt from the surfaces of the lens molds for molding a plastic lens, and to clean the surfaces of the lens molds without leaving water discoloration or stains thereon. <IMAGE></p> |
