摘要

A self-cleaning step for cleaning an elastic abrasive body 231 itself by pressing the rotating elastic abrasive body 231 against a pressing member 221 to deform the elastic body 231 while supplying slurry L containing abrasive to the elastic abrasive body 231 so as to clean the elastic abrasive body 231 is added to a scrub cleaning step in which a plastic optical component 1 is rotated and the rotating elastic abrasive body 231 is pressed against a surface of the plastic optical component 1 while supplying slurry L containing abrasive between the surface of the plastic optical component 1 and the elastic abrasive body 231 so as to clean the plastic optical component 1.
