How to talk to the person in charge about cleaning the air conditioner in the hotel?

Go to the hotel front desk for consultation.

Have the staff contact the hotel manager. Talk to the manager.

First find the person in charge of this unit, then find him, and then let him know who you are and what you do. Just remember to find the right person. Seeing is believing, and the effect is the first. No more than two situations. One is that hotels and other units are willing to clean, so they will directly charge cleaning fees. The other is that they don't want to clean for the time being, that's fine, cleaning is free. There is only one condition: after cleaning, put a big wigley cleaning adhesive label on the air conditioner shell (usually the cabinet machine). This air conditioner has undergone professional cleaning, disinfection and sterilization.
