Abstract
A method and apparatus for washing the surface of an object in which a rotating brush is provided. The bristles of the brush are supplied with a washing liquid through a hollow shaft for a limited angular rotation so that the washing liquid effectively is transmitted to the ends of the bristles substantially only during the time they make contact with the surface.
