Disinfection supplies include ether, 75% alcohol, chlorinated disinfectants, peroxyacetic acid, etc. You can usually use 75% alcohol for hand disinfection, which is fast and effective, or you can use 75% alcohol for wiping small areas, such as cell phones and door handles. It is recommended that 75% alcohol not be used for disinfecting large areas of air because of its low ignition point, and that chlorinated disinfectants be used for spraying. The concentration of chlorine disinfectant is usually around 2‰ or 5‰, usually 2mL of chlorine disinfectant or 5mL of chlorine disinfectant can be put in 1000mL of water, and the virus can be effectively inactivated after 30 minutes of spraying.
