Abstract: An apparatus for removing dirt from an exposed film as it is advanced to an image developing unit includes a scrub roll with a spongy surface and a second roll in engagement therewith for transporting the film. A conduit with perforations directed at the scrub roll is positioned thereabove and is connected to a source of flushing liquid. The transport and scrub rolls are driven co-currently at different surface speeds to generate a scrubbing, shearing action along with simultaneous wetting of the film surface to remove most of any dust or dirt previously carried by or embedded in the surface of the film.
