If there are no professional disinfection personnel in the school:
Suggestion 1: outsource to a professional disinfection company for disinfection, and you only need to monitor whether the disinfectants they use are in compliance.
Recommendation 2: directly disinfect CELA's weak acid hypochlorous acid, whether it is for people or things. Its biggest advantage is that it is safe to human body, and its disinfection is 80 times that of 84, so it is good to use it directly without dilution. Of course, the cost will be higher. If it is a strong private school, it is recommended to use CELA's hypochlorous acid generator to reduce the cost.
