Dr.Clo is
an oxygen-based sterilizing disinfectant, not a chlorine-based disinfectant. It is a product that sterilizes and disinfects a space rather than an area by vaporizing chlorine dioxide. Chlorine dioxide gas is a domestic patented product designed to keep and release at a constant ppm in micro-steam state, and sterilize and disinfect the surrounding space for 24 hours.
