PROBLEM TO BE SOLVED: To provide a door cleaner capable of enhancing partial sweepability by a simple means. SOLUTION: This door cleaner of a coke oven has a nozzle header 1 rotatable around the rotation shaft P which extends toward the section to be swept of a furnace cover and a plurality of nozzles 2A and 2B arranged at the end of the nozzle header 1 which can jet high pressure water against the section to be swept. The inclinationβof the jetting shaft N of the nozzle 2B which is part of the plurality of the nozzles to the rotation shaft P of the nozzle header 1 is different from the inclinationαof the jetting shaft N of another nozzle 2A to the rotation shaft P of the nozzle header 1. The cleaner enables preferential cleansing of the section with a large amount of deposits while securing the same range of sweeping as the conventional one by a simple mechanism.
