    摘要: A cleaning and passivating treatment for metals comprising an amphoteric surfactant which is a caprylic acid derivative of imidazoline compounds. The treatment is substantially free of amines, alkanolamines and phosphates. The preferred treatment includes small quantities of borate ions and molybdate ions. In addition a nonionic surfactant may be added as a foam control agent.
