Biggie 6oz Anti-Fog Lens Cleaner Spray

The Biggie is Z Clear's longest-lasting workhorse — a 6 oz bottle of premium anti-fog lens cleaner that delivers about 600 cleanings per bottle at the lowest cost-per-spray we offer. Built for everyday use, big surfaces, and the riders, skiers, and pros who clean a lot of lenses.

Key Benefits

• 600 cleanings per bottle — lasts the average user 1–2 years
• 8–12 hours of anti-fog protection per application, even in extreme cold or humidity
• Coating-safe — no alcohol, no ammonia, no abrasives
• Anti-static repels dust between cleanings
• Oleophobic reduces fingerprints and skin oil residue
• USA-made in Utah, small-batch formulated

Built For

• Motorcycle helmets and visors — no fog at 60 mph (see motorcycle guide)
• Ski and snowboard goggles — cold-tested, won't crystallize (see skier guide)
• Prescription glasses, sunglasses, and safety glasses — daily use, AR-coating safe
• Welding helmets, face shields, and full-face PPE
• Camera lenses, scopes, binoculars, dive masks

Compatible With Every Lens Coating

Z Clear is alcohol-free and pH-neutral. Safe for: anti-reflective (AR) coatings (Crizal, ZEISS DuraVision, Hoya HiVision, Optifog), polarized films (Maui Jim, Costa, Smith), photochromic / Transitions, mirrored, hydrophobic, and oleophobic finishes. Read more about AR-coating compatibility.

How to Use

Let it dry before you wipe. A cloth on wet spray takes the product off instead of working it in — that one mistake is why people think it didn't work.

1. Spray two pumps directly on each lens
2. Let it dry — spread it with a clean fingertip, or simply let it air-dry. Not the cloth, not yet
3. Buff once it's dry, in concentric circles with a clean microfiber cloth (we make a premium 6"x6" nanofiber cloth and a 5"x5" microfiber multi-pack)
4. Done — anti-fog protection lasts 8–12 hours, dust-repellent for days

Frequently Asked Questions

How long does one bottle last?

Average user gets 1–2 years from a single Biggie 6oz bottle. With about 600 sprays per bottle, even daily users get many months of use.

Is the Biggie safe for AR-coated prescription glasses?

Yes. The Biggie uses Z Clear's pH-neutral, alcohol-free formula — the same one in our 1oz and 2oz Spritz bottles. It's safe for Crizal, ZEISS DuraVision, Hoya HiVision, and all other major AR coatings.

Will it freeze or gel in cold weather?

No. Z Clear is cold-tested through sub-freezing conditions and won't gel, crystallize, or separate. It's the formula trusted by ski patrollers and motorcycle riders in winter.

What's the difference between the Biggie 6oz and the smaller Spritz bottles?

Same formula, different size. The Biggie is built for the workshop, gear bag, or shared family use. For pocket-sized travel, see our 1oz Spritz or 2oz Spritz with Towel.

Does it work on dive masks and swim goggles?

Yes. Safe for tempered glass, polycarbonate, and silicone-skirted masks. Holds up in chlorine and salt water. Read the swimmer & diver guide.
