Disclosed is a cleaning composition for an endoscope cleaning machine which has less foaming even at a low temperature and has excellent cleaning power and storage stability, and cleaning of an endoscope by an endoscope cleaning machine using the cleaning composition. Provide a method. [1] A nonionic surfactant (A) represented by the following formula (1), a fatty acid having 6 to 10 carbon atoms having a branched chain or a salt thereof (B), an antifoaming agent (C) And a cleaning composition for an endoscope cleaning machine containing water, and [2] a method of cleaning an endoscope with an endoscope cleaning machine using a mixture of the above cleaning composition and a protease. R—O — [(EO) m / (PO) n ] —H (1) (In the formula, R represents a branched alkyl group having 7 to 9 carbon atoms, EO represents an ethanediyloxy group, PO represents a propanediyloxy group, m and n are average added mole numbers, and m is 1 to 30) (Hereinafter, n is a number from 2 to 50. “/” indicates that EO and PO may be random or block, and the addition order of EO and PO does not matter.)
