Abstract
A method of cleaning deposited material from a molding surface () of a mold () for forming ophthalmic lenses, including bringing a cleaning head () into contact with the molding surface (), the rotational axis () of the cleaning head () being arranged normal to the molding surface (), rotating () the cleaning head () around the rotational axis () while maintaining the contact between the cleaning head () and the molding surface (), moving the cleaning head () to perform a precession motion () around a central normal () on the molding surface (), while rotating () the cleaning head () around the rotational axis () and while maintaining the contact between the cleaning head () and the molding surface (). During the precession motion () the rotational axis () includes an inclination angle (α) with the central normal () on the molding surface ().
