Z Clear Biggie 6oz Eyeglass Cleaner & Anti-Fog Spray for Glasses — Bottle Only, Made in USA

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
  • Up to 72 hours of anti-fog protection per application, even in extreme cold or humidity — we recommend re-treating daily
  • 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 up to 72 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.

We love it, that's why we wanted to order a 6 oz bottle. So I am very happy we got a larger bottle. One issue I have, after I placed my order a "pop-up" came up stating I would get a 50% discount on my order, I assumed it would be 50% of my order, but I would mistaken or fooled because it was 50% of the new order which I was not aware of and I now have two 6 oz bottles. I tried to call right away to correct my order and I left a message for someone to call me but never received a call-back. Not good customer service. I feel the "pop-up" was very deceiving. In conclusion, my order should have been 24.99 and it turned out to be 42.00. More than I expected. Thank you, I still love your product. Robert Hassemer rhasmr@charter.net 715-828=8940

Z Clear Biggie 6oz Eyeglass Cleaner & Anti-Fog Spray for Glasses — Bottle Only, Made in USA

Over the years I have tried many different lens cleaners. Some worked fine while others added that "filmy" look....ugh. Each time I search on the internet to select this year's eye cleaner and last year I thought,"this is a great eye cleaner!". However after trying out your product, "It's a game changer for me!". I like the anti-fog idea as well as having this product "fill"in the scratches!! I can tell the difference each time I clean the lenses. Thank you for making my life easier and I am thrilled to look through lenses with little to no scratches. Bye....Terri M.

Biggie Lens Cleaner / Anti Fog Spray - 6 oz

Customer photo review of Biggie (6oz.) - Anti-Fog Glasses Cleaner Spray

I use Z-Clear multiple times every day. I don't want to run low on my supply so before I started working on my last bottle of Z-Clear I bought (this order) 2 more bottles. When the small bottle I carry with me runs low I refill it from one of my large bottles. My next order will be small bottles just in case the spray mechanism on the bottle I have becomes defective. Thank you very much Z-Clear!!!!!

Customer photo review of Biggie (6oz.) - Anti-Fog Glasses Cleaner Spray

I use Z-Clear multiple times every day. I do my own cooking so my glasses get dirty easily. I want my glasses to be clean so I need to use Z-Clear often. With all the variant forms of the virus that we must deal with it looks like wearing a mask is not going to end soon. Consequently fogging is an issue that is not going away anytime soon.

Customer photo review of Biggie - Anti-Fog Glasses Cleaner

Always had issues with my sunglasses fogging up during my runs. A teammate of mine gave me some ZClear to try before IMCHOO and it worked great for my swim goggles, bike visor, and sunglasses. Will use this product from now on as nothing fogged up during all 144.6 miles of this race.

Biggie - Anti-Fog Glasses Cleaner

I have constantly dealt with fogged swim goggles. I bought a small sample at an ironman event. I was amazed at how well this product works. Just got my new order in, and the product is just as good as before. Total game changer for me...one less thing to worry about in a race!!

Customer photo review of Biggie - Lens Cleaner & Anti-Fog for Glasses (6 oz.)

I am very happy that I made this purchase. Z-Clear works so well that my only regret is that I didn't think to buy it sooner. The anti fog quality is absolutely phenomenal. I have 3 bottles of Z-Clear. 1 large bottle in my kitchen and my bedroom. The 3rd bottle I have is a small bottle that I carry on my person wherever I go. For cleaning or de-fogging, Z-Clear really is the greatest!!!!!!

Customer photo review of Biggie - Glass Lens Cleaning Solution & Anti Fog Spray (6 oz.)

I am totally satisfied with my Z-Clear. Fogging has been a problem for many months. I kept buying different masks hoping to find a good one. Today after leaving home to get the vaccine I still saw a little fog with a new tight fitting mask. I used Z-Clear 1 time and it lasted all day. I couldn't believe it!!!!! The other spray I had required multiple times in wet weather. Z-Clear is the greatest. I am very happy that I bought the biggie bottle!!!!!!!!

Biggie - Glass Lens Cleaning Solution & Anti Fog Spray (6 oz.)

We found this at the Anoka Game Fair in Anoka MN a couple of years ago. They demonstrated to us and we were impressed even though we thought it was a bit on the high price side. We purchased the set they were offering - eye glass and mirror/window - the Biggie - I think. We have just started to run out of the Biggie so it was well worth the money and has not diminished in how it works over the years. We have used it on our glasses, the bathroom mirror - which works amazingly well, snowmobile helmet shields, etc. It does well past expectations - the snowmobile helmet shields hadd trouble on at below 0 degrees but kind of expected it not to work as well. So satisfied with it we purchased sets for my daughter and son's family.
