For removing a scratch or stain from a surface of a disk such as a CD, a disk cleaner/scourer/polisher device has a scouring member such as a buff. The disk is rotated about its axis, and the buff is pressed against the surface of the disk and rotated also with the axis of rotation of the buff being perpendicular to the surface of the disk, scouring is uniform and does not impair surface flatness. Changing between scouring members, between scratch removal and polishing is facilitated by a lifting mechanism for selectively pressing the corresponding scouring member against the surface.
