Cat Crap Anti-Fog Lens Cleaner

To apply Cat Crap, you first clean your lenses thoroughly with water or standard lens cleaner. Then, you apply a small dab of the paste directly onto the dry lens surface, rubbing it in completely with a microfiber cloth. Finally, you buff the lens gently until the paste is clear and no streaks remain.

Yes, Cat Crap is formulated to be safe for most modern eyeglass lenses, including those with anti-reflective (AR) coatings and polarized sunglasses. The paste uses gentle, natural ingredients rather than harsh chemical solvents that strip optical coatings. However, it is always best to spot-test a corner of the lens first if you have extremely delicate mirror coatings.

Cat Crap is highly popular among skiers and snowboarders because it is extremely effective at preventing goggle fogging in cold, damp conditions. By creating a micro-film over the polycarbonate goggle lens, it prevents the condensation buildup caused by body heat meeting freezing air. It works on double-layered and single-layered goggles alike.

A single application of Cat Crap on eyeglasses or ski goggles usually lasts for a full day of active use, though heavy sweating or rain can reduce its effectiveness. For intense activities like winter hiking or cycling, it is recommended to reapply the paste every morning before hitting the trails. The small jar fits easily into a pocket for quick touch-ups.
