Many people almost never clean a refrigerator, let alone sterilize it. As everyone knows, a refrigerator that has been used for a long time may become a pollution bin. According to relevant departments testing of refrigerators that are not sterilized during use, the total number of bacteria in some refrigerators is as high as 10,000 to 30,000 per square centimeter. Therefore, regular cleaning and disinfection of the refrigerator is an important matter that cannot be omitted, and disinfection should be carried out at least once a month.
Before sterilizing the refrigerator, first remove the food stored inside, unplug the power plug, shut down, and then defrost and wipe the inner liner and accessories before disinfection. You can choose one of the following disinfection methods:
Wipe with a soft cloth dipped in a 75% alcohol or acetic acid solution, or a 0.1% solution of Neogel. Close the door for 15-30 minutes, then scrub with water and drain.
Spray with 0.05% ～ 0.1% peroxyacetic acid solution. Excessive concentration of peroxyacetic acid solution will have a certain corrosive effect on the metal, so pay special attention to the concentration. Close the door for 20 to 30 minutes, and scrub it.
