Abstract: An apparatus for cleaning the sideview mirror or mirrors of a vehicle in a washing line. A cleaning mechanism, such as a spray nozzle or drying nozzle holder, that essentially extends in a vertical direction is disposed to the side of a vehicle. The sides of the vehicle, along with the sideview mirror or mirrors thereof, are conveyed to pass along the cleaning mechanism. In order to improve cleaning of the sideview mirrors, a mirror-cleaning element, such as a spray nozzle element or a drying nozzle element, is disposed on the cleaning mechanism and is directed in the transport direction of the vehicle. This mirror-cleaning element can be a follower element by being mounted on a lever arm.
