γγ84 disinfectant can be used to inactivate novel coronaviruses. Current research on the physicochemical properties of the novel coronavirus shows that the virus is very sensitive to chlorinated disinfectants, and the main active ingredient of 84 disinfectant is sodium hypochlorite, so it can be used for disinfection during the novel coronavirus outbreak.γγIn daily home life, the specific disinfection method is to first dilute 84 disinfectant to the appropriate concentration according to the instructions, and then wipe furniture, walls, floors, doors, windows, toys and other supplies with it to disinfect, but not to disinfect food and clothing. After wiping and disinfecting, pay attention to opening windows and ventilating to avoid the inhalation of volatile chlorine ions by the human body, which may cause adverse consequences.
