Therefore, it is an important matter that the refrigerator is cleaned and sterilized regularly, and the refrigerator should be sterilized at least once a month.
The common sterilization and disinfection method is to use a disinfectant to scrub after the power supply is pulled out and the machine is shut down after power failure, corners (the places where bacteria and viruses are most easily bred) are inevitably missed in the scrubbing, and the chemical sterilization and disinfection method can kill bacteria, but brings secondary pollution to the environment.
