Using a microwave oven to sterilize utensils and other items, according to relevant experiments, it has been proven that pathogenic bacteria can be completely killed in 3 minutes. If you buy cooked food products, heating them in the microwave for 30 seconds will basically kill E. coli and pathogenic bacteria. When sterilizing tableware such as tableware, it is best to dip some water in it before putting it in the microwave. This can greatly improve the sterilization effect and shorten the disinfection time. If kitchen towels, rags and other high-water content items are heated in a microwave oven for 3 minutes, E. coli and Staphylococcus aureus can be completely killed. If you are sterilizing items with a moisture content of less than 70% in a microwave oven, it is best to place a small bowl of water next to them to prevent poor sterilization effects and scorching.
