Is there any easy way to disinfect and sterilize a room?

Always open windows to maintain indoor air circulation.

1. Air cleaning method. To keep indoor air fresh, windows must be opened for ventilation. Open windows for 10 to 30 minutes each time to allow air to circulate and eliminate germs from the outside.

2. Bleach powder disinfection method. Bleaching powder can inactivate enzymes in bacteria, causing them to die. Use 1% to 3% bleaching powder supernatant to sanitize tables, chairs, and floors.

3. Vinegar disinfection method. Vinegar contains acetic acid, which has a certain bactericidal ability and is often used for indoor air disinfection. For a room of 10 square meters, you can use 100 to 150 grams of vinegar, dilute it twice with water, put it in a bowl and steam it with slow fire. Keep the doors and windows closed when fumigating.

4. Disinfectant spray and fumigation disinfection Chemical disinfectants commonly used for air spray and fumigation disinfection include: chlorine-containing disinfectants, peracetic acid, glutaraldehyde, chlorine dioxide, etc. The effect of using glutaraldehyde to disinfect the air by spraying or heating is basically the same. The relative humidity is 80%-90%, the dosage is 250-500mg/m3, and the effect is 30 minutes. A concentration of 1%-2% can be used for spraying, and a slightly higher concentration solution can be used for heating and fumigation. Chlorine dioxide activated disinfectant is also an excellent and harmless environmental disinfectant. The spray disinfection concentration is 200-500ppm and the action lasts for 15-30 minutes. In addition to its disinfecting effect, it also has a deodorizing effect.
