A method for manufacturing molecular chlorine dioxide, by the addition of potassium iodide to a solution of alkali metal chlorite. The metal chlorite and the potassium iodide are kept separate, until the need for the generation of chlorine dioxide arises--to ensure long-shelf life. After initiation or activation of the chlorite anion to form chlorine dioxide, the beneficial properties of chlorine dioxide can be used, for different health and cosmetic purposes. Such uses include the treatment of herpes, dandruff, acne, skin rashes (e.g. poison ivy), ulcers, bed sores, warts, nail fungus, athletes foot, sun burn and gum disease; and as an antiseptic, disinfectant, and general deodorant form refrigerator sprays to oral mouthrinses.
