In order to prevent cross contamination, the cleaning facilities in the clean workshop should be dedicated according to the product characteristics, process requirements and cleanliness levels.

Cleaning tools generally adopt centralized fixed and portable mobile vacuum cleaning equipment. If the above conditions are not met, you can also use materials that do not shed fibers, such as mercerized towels and nylon cloth, to wipe, generally once or several times a day.

The workbench and tools are generally cleaned once a day; The walls and floors of the 10-1000 level plant are generally cleaned once a week, and the 10000-100000 level plant is cleaned once a month.
