84 disinfectant has some inactivating effect on the new coronavirus. The novel coronavirus is sensitive to UV light and heat, for example, this virus can be inactivated by heating at 56°C for 30 minutes. The main component of 84 disinfectant is sodium hypochlorite, which has strong oxidizing properties and is a high-quality disinfectant. However, due to its high concentration, it is often used after dilution at a ratio of 1:100. The configured disinfectant solution should be used to avoid direct contact with the skin. It can be dipped in a rag and wiped on floors, walls, tables, chairs, toys, tiles, glass, mirrors, etc., but not on clothing or food. After wiping, doors and windows need to be closed to let it work for 10-30 minutes to discharge the chlorine ions so as not to cause harm to human body by inhalation.
