Anti-Fog Cloth for Glasses, Goggles and Visors

Anti-fog cloth for glasses that fog up in winter

The GoGoNano Anti-Fog cloth is a microfiber cloth with an anti-fog treatment. Wiping the lenses with it cleans them and keeps them clear for up to 10 hours, without a spray bottle in your pocket. Glasses fog up when warm, moist air meets a cold lens. This can happen when you come indoors in winter, lean over a hot pan or breathe out under a face mask or scarf.

How to use the anti-fog cloth

1. Clean your glasses and let them dry.
2. Wipe both lenses gently with the Anti-Fog cloth, pressing slightly.
3. Breathe on the lenses to check that they no longer fog.
4. Repeat whenever the effect starts to weaken.

The cloth works on glasses, sunglasses, safety glasses, ski and diving goggles, camera lenses, helmet visors and binoculars. It does not harm anti-reflective or other lens coatings. Our article on how to prevent glasses from fogging up explains why it happens and what else helps.

Keep the cloth working

• Never put the cloth in water or wash it.
• Keep it in its case at room temperature, away from moisture and light, not loose in a pocket.
• Do not use it on contact lenses.
• Wash your hands after use. If your skin reacts, see a doctor.

Replace the cloth when wiping no longer keeps the lenses clear, or when it gets dirty. For everyday cleaning of smudges, use a washable microfiber glasses cleaning cloth and reserve the Anti-Fog cloth for preventing fogging.
