The effective component of 84 disinfectant is sodium hypochlorite, which is a strong oxidant, which is why it can kill bacteria. The higher the concentration of sodium hypochlorite, of course, the stronger the disinfection effect, but the stronger the poison to people, so strong that you have to wear a gas mask.
Generally, 5% sodium hypochlorite disinfection is enough. Another well-known bleaching powder is actually the brother of 84. It is calcium hypochlorite, which has the same effect. So we know that they are highly oxidized and bleached. (Oxidized colored organic matter)
Sodium hypochlorite is unstable, so it will eventually decompose. Sodium hypochlorite becomes sodium chloride (our salt component). Therefore, it depends on the area you wipe and the space size of the area. With time and ventilation, it won't stay in the end.
I hope to adopt.
