The JAWS 2 oz. SeeSafe 2-in-1 Antifog and Cleaner Spray is an anti-fog and lens cleaning solution that can be used on eye wear, safety goggles, safety glasses, face shields, sport goggles, paintball masks, scopes, binoculars, dive masks, swim goggles and so much more. JAWS spit anti-fog gel formula is not recommended for use on small lenses such as swim goggles. All JAWS anti-fogs work with wet or dry applications. When you are applying to a glass lens be sure the lens has been pre-cleaned with JAWS scrub mask cleaner product prior to applying the anti-fog. Anti-fog will perform much better on a clean surface. When you are applying on a plastic, polycarbonate or acrylic style lens be sure to rinse, dunk or wash it first ensuring there is no foreign buildup or objects on the lens. Anti-fog always works better on a smooth, clean lens. Apply a VERY SMALL amount of anti-fog on the inside of the lens. Rub the anti-fog over the entire area with your finger - then, it is important to rinse the product off the lens leaving no residue. Visually check each lens prior to use to ensure there is no product left on the lens. As stated above, all JAWS anti-fogs work with wet or dry applications. When you are applying on a glass, plastic, polycarbonate or acrylic style surface be sure the surface is clean. Both Quick spit and SEESafe can be used to pre-clean the surface prior to applying the product as an anti-fog (2-in-1 Formula). Simply apply Quick spit or SEESafe to the inside and outside of the lens, add water and wash with fingers or a clean damp cloth. Be sure to dry the surface after cleaning prior to applying the product as an anti-fog. Spray a small amount on the dry surface being treated. A larger surface will require more product but over applying is counterproductive. Rub or spread the anti-fog over the entire area. Then, gently buff with a JAWScloth or a clean, lint free, soft cloth only until product haze disappears. It is important not to over buff!
