A cleaning method using a cleaning apparatus having an adhesive sheet, a conductive sheet in contact with a base material of the adhesive sheet, and a pressing member for pressing the conductive sheet onto the adhesive sheet. The pressing member includes a voltage applier, and a pressing force controller which presses the adhesive sheet onto a curved surface of a portion to be cleaned of a vacuum processing apparatus from above the conductive sheet. The method includes pressing the pressing member by a pressing force controlled via the pressing force controller to press the conductive sheet and the adhesive sheet to adhere an adhesive surface of the adhesive sheet to the curved surface of the portion to be cleaned, and applying a voltage to the conductive sheet or applying a voltage having a temporally changed polarity.
