Once dropped into the water, the WASH-IT ball releases its active ingredients with constant speed during the wash and rinse cycles.The WASH-IT ball activates the water molecules for an ion exchange, producing electrolytic oxygen and hydroxide ions. The electrolytic oxygen is a pure, natural cleanser which is absorbed between the stain and fiber reducing the adhesive force of the stain. The stain is actually separated from the fiber with the activated water molecules, then emulsified and dispersed into the water.The activated ions remain on the fiber enabling the fiber to resist the re-deposit of stains on the surface. The chemical reaction is completely safe, gentle and results in a pure, clean, hypo?allergenic wash.The WASH-IT laundry ball does not contain soaps, harmful chemicals, phos?phates, EDTA, NTA or boron compounds. The WASH-IT laundry ball meets all environmental protection criteria which means that it is safe for you and your planet
