Our KleerVu Anti-Fog Guarantee promises that our Anti-Fog cleaner will counteract fog when used as directed, and applied regularly as needed. The frequency of KleerVu application will be dependent on the amount of physical activity exerted and the weather conditions, and will vary. There are some lenses that will not anti-fog with KleerVu, or any other type of cleaner. These excluded lenses include Crizol, anti-reflective lenses, teflon lenses, and other types of lenses with special coatings. For these special types of lenses, we have developed Pristine Lens Cleaner. Pristine is not an anti-fog formulation, and is not guaranteed to counteract fog.
