Polygiene prevents the growth of odor-causing bacteria at the source. The small particles of the Polygiene treatment are trapped by a mechanical binding in all gaps, fiber joints, and holes in the fabric. Thanks to the strong binding forces combined with the big surface provided by the fabric, a big amount of treatment can stick to the fabric. It stays in the fabric permanently in the same way a grass stain stays on a white pair of trousers, wash after wash.
