PROBLEM TO BE SOLVED: To provide a car washing machine that allows a user to know the content of impurities included in waste water. SOLUTION: An operation panel allows a user to command car washing operation via a controller of a car washing machine body. The operation panel includes an indicator for indicating the content of normal-hexane extracts being impurities in waste water during car washing. The controller 41 includes a data storage part 42 for storing each impurity concentration in the waste water previously calculated corresponding to each of plural types of car washing courses provided in the operation panel, a concentration reading part 43 for reading an impurity concentration that corresponds to the car washing course selected by using the operation panel, and a data output part 44 for outputting the concentration read by the concentration reading part to the indicator 50.
