A cleaning fluid spray device according to an embodiment of the present invention is provided with: a circulation tube for circulating cleaning fluid to a spray nozzle; a rotating brush for cleaning internal parts of this circulation tube; and a magnetizing unit for magnetizing a rotating shaft for this rotating brush. The rotating brush has: the rotating shaft, which rotates centered in the axial direction of the circulation tube; and brushes provided along the longitudinal direction of this rotating shaft. In the cleaning fluid spray device, magnetic contaminants in the cleaning fluid present within the circulating tube are attracted to the rotating shaft magnetized by the magnetizing unit, the magnetic contaminants eliminated from this cleaning fluid, and the cleaning fluid after elimination of the magnetic contaminants sprayed onto a metal plate surface of an object to be cleaned from the spray nozzle. |
