ABSTRACT:
A cleaning and sterilizing method for removing organic matter adhered to the surface of an endoscopic camera instrument, and effectively exhibiting bacteria-killing and virus-killing effects of acidic water uses, as a cleaning bath, an alkaline-water-producing electrolysis bath partitioned by a separating membrane and having electrodes on both sides, and conducts preliminary cleaning of an endoscopic camera instrument inserted in the cleaning bath by ultrasonic cleaning with city tap water. Subsequently, saline solution is provided to the electrolysis bath to conduct electrolysis, conduct ultrasonic cleaning with alkaline water obtained by the electrolysis, introduce acidic water in the acidic water generation bath and conduct sterilization-cleaning, and further to conduct ultrasonic cleaning with city tap water. Then, the endoscopic camera instrument is dried with warm air as the case requires.
