Anti-Fog for Boating & Marine — Windshields, Sunglasses & Optics

Anti-Fog for Boating & Marine — Clear Water, Clear Vision

On the water, fog, salt spray, and glare all fight your vision at once. Z Clear keeps your boat windshield, polarized sunglasses, and marine binoculars clear — without the ammonia and alcohol that craze acrylic windscreens and strip the coatings off premium marine shades.

Why Boaters Choose Z Clear

Marine enclosures, isinglass, and acrylic windscreens are exactly the plastics that household glass cleaners ruin. Z Clear cleans and protects them, leaving a hydrophilic film that sheds spray and resists fog and salt haze.

• Safe on acrylic & isinglass — no crazing of windscreens, enclosures, or dodgers
• Coating-safe on polarized sunglasses — the marine essential, protected
• Sheds spray & resists salt haze — water sheets off instead of drying to a film
• Anti-fog for the cabin & helm — clear glass on cool mornings and in the rain
• Made in the USA since 1981

Windshields, Sunglasses, Binoculars & Instruments

From the helm to the flybridge, Z Clear works on every surface aboard — windscreens, polarized shades, marine binoculars, and instrument glass. For scanning the water, see our guide to anti-fog for binoculars and marine optics, and for masks below the surface, our scuba & snorkel anti-fog guide.
