Abstract
Provided are a method of cleaning an endoscope, a washing machine and a washing machine for endoscope, which can effectively clean an endoscope while preventing the endoscope from deterioration. The electrolytic cellcan produce from tap water acidic water with pH of 2 to 5 and the residual chlorine concentration of 50 to 300 ppm. A tank for acidic watercan store acidic water, in which part thereof can be fed to a tank of diluting acidic waterand the rest thereof can be fed to a feed section of concentrated water. A water feed section for dilutioncan feed water for dilution to the tank of diluting acidic water. The tank of diluting acidic watercan add water for dilution from the water feed section for dilutionto part of the acidic water from the tank for acidic waterto adjust diluted acidic water to pH of 2.3 to 5.7 and the residual chlorine concentration of 10 to 60 ppm. The feed section of concentrated watercan feed the rest of acidic water fed from the tank for acidic waterthrough a channel connection portto a channel port of an endoscope.
