In the daily life of the family, cleaning is the main focus. When tap water is properly combined with detergents to clean and wipe objects and surfaces, it can achieve a better cleaning and sanitation effect. The routine use of disinfectants in households is generally not recommended. So under what circumstances are disinfection measures recommended? Disinfection is necessary only when there are patients in the home, especially those with infectious diseases when someone in the home has come into contact with patients with symptoms such as colds and fevers; or after outsiders come to visit, etc., disinfection is necessary.
2. Which disinfection methods to choose
For ordinary households, physical disinfection methods should be used as much as possible when choosing disinfection methods.
- The air is ventilated by opening windows regularly, generally 2–3 times a day depending on the situation, each time not less than 30 minutes, and keep warm in winter.
- Heat-resistant items such as tableware should be sterilized by steaming, and in 100 degrees boiling water and steam for 5 minutes, or using a qualified disinfection cabinet according to the instructions, a good disinfection effect can be achieved.
- Clothes and bedding are mainly exposed to sunlight, or washed and disinfected with disinfectant laundry detergent. 4. Disinfectant can be selected for key parts of frequently touched surfaces, such as door handles, desktops, toilets, faucets, children’s toys, etc., and do not spray disinfectants on a large area.
