How to clean the accelerator in 4s shop

You know, the inner wall of the new throttle chamber is not as clean as you think, and there is nothing. Instead, it is coated with a special coating, which has the functions of dustproof, antistatic and reducing adhesion. At the same time, the throttle shaft is coated with a layer of lubricant to make the throttle run smoothly. Improper use of cleaning agent in 4S or quick repair shop will not only destroy the coating on the throttle cavity wall, but also wash away the lubricating oil on the throttle shaft, and even cause great corrosion, softening and expansion of the skirt and oil seal of the throttle idle motor.
