After each breast pumping, the milk storage container and the breast pump's milk collection parts must be completely separated, soaked in hot water and detergent or rinsed, if hot water and detergent are not available, boiling water is recommended. It can also be cleaned in a dishwasher. After washing, it must be air-dried and stored under dry conditions. Chemical disinfectants are not recommended because they are easily inactivated, have unsatisfactory disinfection effects, and may expose infants to the risk of insufficiently rinsed containers and chemical disinfectants. The breast pump does not need to be sterilized, but if the mother really wants to sterilize it, it is enough to sterilize it once a day. Put it in a sterilizing and drying pot to sterilize and dry it once.
