The high-speed rail has high running speed, is designed into a streamline type for overcoming air resistance, has more curves and curved surfaces on the surface, and is difficult to meet the requirement of cleanliness by adopting a common cleaning method. During the running process of a high-speed rail, static electricity is easily generated on the outer surface of the train, and dust is adsorbed. In addition, dust accumulation and rust on the vehicle body are also caused by weather or the like. Although the high-speed train is cleaned regularly, certain adsorbates are difficult to clean, and a large amount of yellow spots and stubborn dirt appear on the shell of the high-speed train after the high-speed train is accumulated for a long time. The macula lutea and stubborn dirt which are difficult to clean are mainly formed by bonding dust, iron powder and organic matters under water vapor and certain temperature.

At present, alkaline cleaning agents are commonly used for cleaning high-speed rail trains, paint and rubber on the outer surface of the high-speed rail can be damaged after long-time use, and even the outer surface of the high-speed rail becomes yellow, so that the appearance of the outer surface of the high-speed rail is seriously influenced. In addition, the waste water generated by using the cleaning agent is difficult to treat, so that the environmental pollution is serious. Therefore, in order to enhance the anti-pollution capacity of the surface of the high-speed rail train, prolong the train cleaning period, reduce the damage of the cleaning agent on the surface of the high-speed rail train and simultaneously reduce the discharge of polluted wastewater; aiming at the surface property and the use environment of the shell of the high-speed train, a novel efficient cleaning protection product is necessary to be developed for the protection of the shell of the high-speed train, and the cleaning protection process flow of the high-speed train is optimized.

The pH value of the cleaning agent for the outer surface of the high-speed rail is close to 7, the problems that the paint and rubber on the outer surface of the high-speed rail are easily damaged by the conventional cleaning agent, and the environment is seriously polluted by waste water generated by using the conventional cleaning agent are solved, and the cleaning rate is up to more than 93%.
