PROBLEM TO BE SOLVED: To provide a cleaning apparatus for a light projection face and a light receiving face of a probe for detecting a particle condition in treating water capable of removing efficiently stain on the light projection face (glass surface) of a light projection part and the light receiving face (fiber end face) of a light receiving part, by a cleaning liquid. SOLUTION: This cleaning apparatus having the light projection part for emitting the laser beam from the light projection face in its tip into the treating water, and the the light receiving part for receiving scattered beam generated by collision of the emitted laser beam with a particle in the treating water, by the light receiving face in its tip, and for cleaning the light projection face in the tip of the light projection part of the probe for detecting a particle condition in the treating water by a laser beam comprises a long cleaning liquid supply part having a light projection face injection nozzle capable of blowing the cleaning liquid onto the light projection face at 40-50°of angle from the light projection face, in the vicinity of a tip part thereof.
