What is the best sterilization effect

Many people feel insecure about the environment they live in, and always feel that everything carries bacteria. They wash their hands countless times a day, which is mostly due to mysophobia. However, sometimes sterilization is indeed necessary in homes, offices and other places to eliminate harmful substances, but what is the best sterilization effect? If you have a cold, it is best to boil some white vinegar to kill bacteria, or steam disinfection is also a good idea.

1. Physical disinfection method.

(1) Ventilation. Open windows frequently to promote indoor air circulation and reduce or eliminate indoor pathogens. Ventilation time can be longer in summer, and in winter the windows should be opened 2 to 3 times a day, each time for about 20 minutes.

(2) Ultraviolet disinfection method. Expose the items to be disinfected directly under sunlight. The stronger the sunlight and the longer the exposure time, the better the sterilization effect. When exposing the items to the sun, turn them over frequently so that all sides of the items can be directly exposed to the sunlight. The purpose of disinfection can be achieved within 4 to 6 hours. Or use ultraviolet light, which has a better disinfection effect on objects with smooth surfaces. The room must be clean before disinfection, and people must leave during irradiation. The disinfection time should be more than 30 minutes.

(3) Incineration disinfection method. It will have no preservation value, be infected with bacteria and be flammable. Burn the burnable items with fire. When burning toilet paper, cotton balls, and tissues, pay attention to safety and keep them away from flammable and explosive items to avoid burns or fire.

(4) Boiling disinfection method. Wash items that are not afraid of boiling, such as clothes and dishes, and boil them in boiling water for 15 minutes to achieve the purpose of disinfection.

(5) Steam sterilization. Place the items for sterilization in a steamer or steam pot, and cook for 15 minutes after the water boils.

2. Chemical disinfection method.

(1) Wiping method Wiping contaminated objects with chemical liquid is often used for disinfection of floors, displayed items, etc. You can use 0.5-3% bleaching powder clarified liquid, 2% new disinfectant, etc.

(2) Soaking method Soak the items to be sterilized in the disinfectant. This is mostly used for daily utensils that cannot or are inconvenient to steam or cook. The soaking time depends on the nature of the items and the solution, and then rinse with clean water.

(3) Fumigation method. Disinfection is carried out using the gas produced by disinfectants, and is often used to disinfect rooms and indoor surfaces where infectious patients have lived.

(4) Spray method. Put the disinfectant into an ordinary sprayer and spray it into the space. Close the doors and windows for 1 hour after spraying and leave temporarily.
