An apparatus for washing out of printing blocks of the "Nyloprint" type or the like is provided, comprising a brush device which is coupled to a driving means and adapted to be moved across a printing block which, during the washing, is fixedly disposed in a container with a cleaning bath in which the printing block and the brush device is immersed. The brush device comprises at least two brush units which are rotatably mounted about respective rotational axes, and which by means of a motion mechanism are adapted to move along a circular path during simultaneous rotation about their rotational axes, the brush units having an orientation and a size resulting in mutual overlapping during the rotation of said units.
