Purosol Microfiber Cloths used for cleaning optics and screens are not all created equal. Purosol cloths stand out from the crowd for several scientific reasons which start with the fiber itself and ends with the precise way it is woven.The resolution of high-powered microscopy told Purosol scientists what happened when different fibers reacted to the Purosol formula to derive the five factors of size, elasticity, softness, absorbency and weave that make up Purosol’s unique composition. After extensive testing and refinements Purosol microfiber cloths were born.
