The 84 sanitizer is what kills the new coronavirus. The new coronavirus is sensitive to ultraviolet light and heat, and fat-soluble disinfectants such as 56°C for 30 minutes, ether, 75% ethanol, chlorinated disinfectants, peracetic acid and chloroform are effective in inactivating the virus. The new coronavirus is generally difficult to survive in vitro, where it survives for a few hours and is easily inactivated because the virus has no cell wall and is a single-stranded RNA virus. The spread of the new coronavirus is mainly through droplet transmission or contact transmission, so spraying disinfectant in the air can effectively prevent the spread of the virus. 84 disinfectant is a chlorine-containing disinfectant, which is mainly used to disinfect the environment and the surface of objects, and it contains strong decontamination ability, which can eliminate enteric pathogens, septic cocci, bacterial spores, and viruses. Therefore, 84 disinfectant can kill the new coronavirus, but in the use of 84 disinfectant, should pay attention to the proportion of dilution, in the spraying should pay attention to wear gloves and masks, do not touch the original liquid with their hands.
