Always mix up a fresh solution every 24 hours, each shift or when visibly contaminated.

TECHNICAL: Hypochlorous acid (HOCl or HClO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO. HClO and ClO are oxidizers, and the primary disinfection agents of chlorine solutions.
