Abstract: A device for cleaning printing rollers. This device is capable of effectively cleaning rollers through a brushing process and a washing-drying process, the former process being conducted in a liquid-cleanser-contained tub wherein a sandpaper-brush or a wire-brush makes a pressing contact with a roller to be cleaned in the state that said brush rotates around a vertical axis simultaneously moving to and from axially along the roller, the roller resting on a pair of parallel rollers keeping a suitable distance between them and being disposed axially parallel with the roller to be cleaned, the pair of rollers in this state transmitting their motorized rotation to the roller to be cleaned so as to add to the brushing effect, the brushed roller thence being placed under a washing-and-drying process at the other tub wherein a showering device and a blade function effectively for the washing and drying work respectively.
