Jaws Spit Anti-Fog Gel Solution Defogger for Snorkel Mask, Scuba Divers, Paintball, Eye Wear, Sport Goggles, Made in The USA

I don't know the formula to this (although probably a detergent/soap variation) but I know what it does. Fogging on a surface is actually just thousands of tiny water droplets on that surface. After you take a shower, look closely on your bathroom mirror. You will notice that its just thousands and thousands of droplets that due to their spherical shape, diffuse light transmission.I applied Spit to a part of my bathroom mirror and took a nice hot shower. The Spit covered part was NOT foggy. However, when I looked closely, the water was there, but just not in droplet form. I believe this product, like soap, removes the surface tension of the water droplets, and so they can no longer form tiny droplets, but instead, condense flatly upon their surface. So the treated part of the mirror had a watery glaze on it, but was more or less clear.I noticed the same when I used this on my motorcycle helmet face shield. It was 40 degrees, very cold, so normally, my face shield fogs up instantly. But after 30 minutes of riding, I noticed that my face shield was actually subtly wet, not foggy, but a thin watery glaze had collected on the inside. The vision was slightly warped due to this water glaze, but perfectly usable and much preferred to a grey fog that normally forms.The only drawback is the product eventually looses its effectiveness and needs to be re-applied - surface tension removal of water is usually done by molecular bonding to the water molecule itself, which means a molecule of tension remover has to get consumed with every water molecule it de-fogs. My bathroom mirror has lasted 2 good hot showers so far, which is a lot more fog than goggles or face shields would generate. I will update with how many days Spit has lasted on my mirror.

There are many things I like about this product:First of all, it works great. Very rarely there is a little fog in the mask, but that only happens when it does not seal properly and water pours into the mask. On several occasions I dug this little bottle out from my dive bag after using the dive boat's regular antifog, because it didn't work as well.It's very viscous, so once the bottle gets a little emptier, shake it a little to get some spit to the nozzle. When it gets very empty I might end up diluting it with a little water to get it out easier. However, this bottle has lasted a few years of diving and snorkeling already.It's biodegradable, which means it will not harm fish and coral. As divers, we should take care of the place we love! The often used baby shampoo is not reef friendly, even if it does not burn in your eyes, unless it's also made of biodegradable ingredients.The name itself is worth a laugh every once in a while.Also, check out the company's other products, like Jaws Slosh Wetsuit Shampoo, 4 oz., which works great on stinky wetsuits/boots, smells great and is biodegradable, as well!

One of the most inconvenient things about riding a motorcycle with a full face with glasses is when your lenses fog up from your own breath, or from the ambience. I first tried the quick squit: it worked on swim goggles rather well, so at the least it wasn't a waste; however, the quick spit did not work on prescription lenses. The quick spit bottle even states that it is NOT RECOMMENDED FOR PRESCRIPTION LENSES, but the description on the website failed to mention it. Now, I decided to get the anti fog gel apart from the quick spit. Both the gel and the spray are annoying to apply, but the gel does work on prescription glasses. After my OCD buffed it till I was someone satisfied, I put my helmet on and tried on both pairs of glasses that applies the spit to: my glasses no longer fog heavily. Some fog may build up, but it quickly dissapates, not really posing much of a disturbance. When applying on small lenses, definitely go smaller than a pea size. The slightest bit too much makes it difficult to buff the lenses easily. You have to keep buffing to get the smears, streaks, and heavy haze off. The application is extremely annoying, but it appears to last for more than one day. Will be testing out my glasses on an actual bike ride later. I'll see how it affects visibility and how effective it is in use.

Don't let the MISLEADING packaging scare you. Yes, this gel product does indeed have a "not intended for swim goggles" on it and I was thinking of returning it to get the spray. I'm sure glad I didn't .... I decided the price was such that I could try to see what made it suitable for a diving mask but not for swim goggles. And if it didn't work then a few $ lost and maybe a damaged google or an irritated eye. So I put a very small drop on each lens, Thoroughly rubbed it, and then thoroughly rinsed it. Presto!!! No issues whatsoever. Works EXTREMELY well. I believe I know why the vendor has that MISLEADING labling in the bottle. If anyone wants to know my theory then just respond to this post and with your email address and I'll send you a direct message. Happy swimming !!!
