Frequently Asked Questions

How long does one bottle last?

Average user gets 3–4 years from a single Biggie 6oz bottle. With over 1,000 sprays per bottle, even daily users won't run out for over a year.

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.
