Disclosed is a process and apparatus for cleaning cylindrical substrates such as photoreceptor drums and the like. The process comprises: coaxially aligning a slotted annular nozzle around the outer periphery of one end of a cylindrical substrate to be cleaned; creating relative movement between the nozzle and the cylindrical substrate in a direction parallel to the axis of both the nozzle and the drum; and directing a stream of carbon dioxide snow particles from the nozzle against a continuous ring shaped zone around the outer surface of the cylindrical substrate to incrementally and progressively clean the outer surface from the one end of the substrate to the other end.
