There is disclosed apparatus (10) for cleaning an exposed surface (11) of an optical element (12), such as the exposed optical surface of a wide angle lens installed on a vehicle. The apparatus includes a collar (30) arranged to be disposed circumferentially around, and to rotate around, an axis (16) of the optical element which the apparatus is arranged to clean, and a wiper arm (20) coupled to the collar so as to rotationally clean the exposed surface as the collar rotates.
