Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a detergent for a car air-conditioner that has cleaning performance and excellent antibacterial, antifungal, and deodorant properties and also maintains a stable effect over a long period of time without interfering a function of drive member, such as an evaporator, by exhibiting a good rust-preventive property. SOLUTION: The detergent for the car air-conditioner is obtained by injecting nitrogen gas as a propellant into a solution and adjusting an injection pressure to be 0.6-0.9 MPa. The solution comprises, based on the total amount of the detergent, (A) 0.1-5 mass% of a di-long chain alkyl, di-short chain alkyl ammonium carboxylic acid salt, (B) 0.5-5.0 mass% of a plant extract, (C) 0.1-5.0 mass% of an organic rust-preventive agent having no halogen atom, and (D) 1.0-10.0 mass% of a nonionic surfactant having no halogen atom with the balance of an alcoholic organic solvent.
