Cleaning process for high-cleanness butyl rubber stopper

The invention relates to a cleaning process for a high-cleanness butyl rubber stopper. The butyl rubber stopper is accurately weighed, hairs, fibers and other wee solid impurities attached to the surface of the butyl rubber stopper due to the electrostatic effect are removed from the butyl rubber stopper to be cleaned through an electrostatic hair impurity removing machine; by means of an automatic feeding machine, the butyl rubber stopper is placed in a fully-automatic butyl rubber stopper washing machine loading barrel; water is added until the mixed washing water level is obtained, a cleaning agent is added, high-cleanness nitrogen is sprayed into the bottom of the washing machine, mixed washing is carried out, and the water temperature is achieved; after mixed washing is finished, an air jet device is started, a water inlet valve is opened, and static overflowing is carried out; the air jet device is started, the high-cleanness nitrogen is sprayed in, and jet overflow rinsing is carried out; the water inl
