Current research data shows that 84 disinfectant has a clear effect on the elimination of the new coronavirus. 84 disinfectant is mainly composed of sodium hypochlorite, which needs to be diluted to a suitable concentration before use in daily life. The diluted disinfectant can be used for wiping and disinfecting home items, such as floors, walls, tiles, tables and chairs, glass, sinks, mirrors, toilets, doors and other surfaces. After wiping and disinfecting, windows should be opened and ventilated so that the volatile chlorine ions can be discharged from the room as soon as possible to avoid health effects due to inhalation.
