DON & JON'S ANTIFOG EXTREME contains more active ingredient designed for surfaces exposed to extremely wet environments where splashing can remove the antifog agent from the surface you are trying to prevent condensation on.DON & JON'S ANTIFOG EXTREME uses leading edge chemistry to prevent small water droplets from forming on protective eyewear, glass and plastic surfaces, lenses and more. DON & JON'S ANTIFOG EXTREME accomplishes this without the use of preservatives found in similar all natural antifog products. All natural antifog products use ingredients that can stimulate biological growth thus use preservatives that release formaldehyde to inhibit growth. Because our active ingredient is inert there is no need for preservatives. DON & JON'S ANTIFOG EXTREME works by decreasing the surface tension of water. Without DON & JON'S ANTIFOG EXTREME waters high surface tension results in the formation of many small water drops that distort light and impair vision.*Active ingredient natural color is amber in tone which is not visible once applied to surface.
