If you are worried about viruses and bacteria, you can spray the surface of the article with a physical disinfectant spray such as Wujing, which will not cause harm to the human body.

Some households with special needs will use disinfectants to disinfect, usually, household disinfectants can choose chlorine-containing disinfectants (such as "84" disinfectant) and alcohol-containing disinfectants (such as 75% alcohol). For example, to disinfect floors and walls, you can prepare a chlorine-containing disinfectant with a concentration of 1000mg l. The disinfection time should not be less than 15 minutes; For the disinfection of surfaces such as desktops, doorknobs, faucets, etc., a chlorine-containing disinfectant with a concentration of 500mg l can be prepared for 30 minutes, and then wiped clean with water.

The correct way to disinfect a room is as follows:

It should be noted that when fumigating and disinfecting with vinegar, the effect of closing doors and windows can be better.

If conditions permit, you can install a 30-watt low-ozone ultraviolet lamp, and when you usually go out, you can kill microorganisms in the air by irradiating it for more than 1 hour.

Mash the traditional Chinese medicine mugwort leaves, cangshu, etc., and then ignite it, smoke for half a day, the most convenient way is to point sandalwood and other disinfectants indoors, and the smoked room can also play the role of disinfecting the room, and it is to use the liquid peracetic acid, pour it into a corrosion-resistant container, and then heat it to vaporize, take away the corrosive items in the room when steaming, and the room can be steamed for 1 hour, and it should be ventilated after steaming.

Finally, it is fumigated with vinegar for home use, add 200 ml of vinegar and pour it into clean water, boil it slowly in a kettle, and close the room for 1 hour.

Regularly opening doors and windows for natural ventilation can effectively reduce the number of microorganisms in the indoor air, improve indoor air quality, and adjust the microclimate of the room, which is the simplest and most effective method of indoor air disinfection. The natural ventilation effect is affected by whether the ventilation of the room is good and the outdoor air quality, the room is well ventilated, the outdoor air is fresh, and the ventilation effect is good.

Spray can be used with a concentration of 1 2, and a slightly higher concentration solution can be used for heating fumigation. Chlorine dioxide activated disinfectant is also an excellent and harmless environmental disinfectant, with a spray disinfection concentration of 200 500 ppm and an effect of 15 to 30 minutes.
