84 disinfectant is a chlorine-containing disinfectant with sodium hypochlorite as the main ingredient, which is mainly used for disinfection of various surfaces and the environment. Sodium hypochlorite is a strong oxidizing agent that can oxidize and denature proteins and other substances in viruses, thus providing disinfection. Disinfection with 84 disinfectant must be prepared by reading the instructions in detail. It cannot be sprayed directly and must not be mixed with other detergents or disinfectants during use to avoid poisoning.
