How to disinfect the refrigerator

Many people do not pay attention to the disinfection of refrigerators in their lives. As a household appliance in every household, refrigerators have brought great convenience to people's lives because they can keep food fresh and achieve a chilled effect. Regularly disinfecting the refrigerator can effectively ensure the health of food and avoid food-contaminating bacteria. Therefore, everyone should learn the correct way to disinfect the refrigerator.

Before disinfecting the refrigerator, first take out the food stored inside, unplug the power plug, turn off the machine, then defrost and clean the inner tank and accessories before disinfecting. The disinfection method can be any of the following:

1. Wipe with a soft cloth dipped in 75% alcohol or acetic acid solution, or 0.1% Chlorhexidine solution. Close the door for 15 to 30 minutes, then wipe with clean water and wipe dry.

2. Spray with 0.05%~0.1% peracetic acid solution. Too high a concentration of peracetic acid solution will have a certain corrosive effect on metals, so pay special attention to the concentration. Close the door for 20 to 30 minutes, then wipe it clean.

3. Spray with 2% alkaline glutaraldehyde aqueous solution, close the door for 30 minutes, and then wipe it clean. Glutaraldehyde solution has a small odor, mild toxicity, and is non-corrosive to metals and plastics. Its disinfection effect is better under alkaline conditions. 0.3% sodium bicarbonate should be added for activation before use, but alkaline glutaraldehyde has poor stability, so it is best to prepare it before use.

Of course, there are already many refrigerators on the market that support sterilization and deodorization. Relatively speaking, the hygiene of the refrigerator can be improved a lot. However, the refrigerator still needs to be cleaned regularly, especially for some refrigerators that do not support sterilization and deodorization. Frequent disinfection is still necessary, but you must pay attention to safety when using it and clean it in time.

The above is how to disinfect the refrigerator. I hope it will be helpful to you.
