Chlorine Dioxide is a gas, and remains such at all temperatures over 51^oF. Even when added to water, it does not hydrolyze – but remains a gas, and it is 10 times more soluble, and 250% more effective in water than straight chlorine. This means that may be effectively delivered by water and it is by far the best means for creating the cleanest surfaces, free of soil and bio-burden when used with microfiber.
