Frog Spit is the safest “Green” Earth Friendly anti-fog available, containing NO harmful silicone, alcohol or other petroleum distillates found in many anti-fogs. Easy to apply, Frog Spit anti-fog wipes and solutions were specifically designed as an “Apply and Let Dry” product requiring no rinsing or buffing. Frog Spit® is specially formulated to simply apply and let dry unlike other brands on the market that require rinsing or buffing, which can in-effect remove much of the just-applied anti-fog coating. Frog Spit® anti-fog wipes and solutions go on evenly, in a single transparent layer providing maximum protection against fogging, and is safe and effective for use on any type of glass or plastic optics, like masks, goggles, face shields and protective eye wear.
