What is your best anti-fog?

[scubaPT]

But the trick is how to keep plastic lenses worn inside the mask from fogging. If I can ever do that I'll have a $1.00 prescription mask.

I use Cat Crap http://www.campmor.com/webapp/wcs/stores/servlet/ProductDisplay?productId=608&memberId=12500226 on my eyeglasses when backbacking and it keeps my glasses from fogging up in the rain/humidity. I am not sure how it would work on the plastic stick on lenses though. I've never tried it on my mask because spit is just so much cheaper.

the trick with spit (if you spit) is to get enough all over the mask, and spread it
well. i like to do this at least 20 minutes prior to dive time.

then rinse JUST ONCE, and put mask on immediately.

There was a discussion on this a while back, and someone mentioned that a small percentage of people lack an enzyme in their spit that does the anti-fogging -- if I remember correctly.

That said, I spit in my mask and spread it around right before I get in the water. Never failed me either. You can always tell if you don't spread it around perfectly because a small foggy spot will emerge while diving.

Oh yeah, my OW instructor always said, "The greener the cleaner." Bring up some of that phlem from deep in the throat.

Not that I do this though. But is there any truth to it?

Catherine's method works well. I've had to do that when I used a commercial brand that was totally ineffective.

I've used almost all of the commercial anti-fog solutions, but baby shampoo still works the best.

I use good old spit, I leap into the water, and while waiting for other divers, I remove my mask, spit into it and rub it with my finger, rinse it and put on the mask, if for any reason I have to remove the mask again before submerging, I'll have to do it again (don't know why but it will fog if I don't).
Some times I forget to do the spit drill, and Cathys method is what I'll use, a bit annoying, but I can handle a dive doing it.

On another note, I got an old (8yrs old) US Divers Hawaii II mask that I don't use 'cause I've never been able to make it fog free, through the yrs, I've tried various antifog solutions, shampoo, dish wash fluid and tooth paste scrubbing, never been able to make it fog free. The mask isn't scratched and out of the water the lens looks great and cleans perfectly, but when under water, it will fog no matter what, any sugestions?

This mask is allmost new and doesn't show any sign of wear since it has been used in less than 30 dives and was cleaned diligently after every use.

I'll probably sell it on ebay to get rid of it and get some money back, since I don't want to stick a friend or relative with a fogging mask.

I would vote 500 psi.

Seriously, once you develop the windsheild wiper technique, you will never need defog and rarely spit at all. Just let a little water in to your mask with your head looking at the bottom, and then turn your head from side to side "cleaning" the fog off and blow the thimble of water out. I probably do that several time on every dive.

Not very pleasant if the water temp is 35 degrees. I prefer to leave the mask in place and use a decent FogNot. http://quizbot.com/scuba.htm

People with hot, sweaty heads wearing masks that position the lenses very close to the face will have fogging problems even if they spit huge clots of rancid lungers into the mask repeatedly, until it overflows vile slime. In any case, mouth saliva is a known carcinogen (only if swallowed in small amounts over a long period of time).

Probably the best anti-fog strategy is to be pure of heart, and to live a moral life. Otherwise, noxious fog will surely leak from your nose.

You don't want to screw a friend, but you're more than happy to screw some unsuspecting eBay buyer, eh? Probably some newbie who's all excited about diving will buy it, only to be hindered by your mask. Who knows, it could be a real newbie buying it, causing undue distress under water.


If you wouldn't sell it to a friend, why would you want to screw someone on eBay?

Hopefully you don't believe in karma. Oh yeah, and remind me not to buy anything from you.

I'm not planning on screwing nobody, but someone with a need for a prescription mask may need a perfect frame for a fraction of the cost of a new mask, say $10.00 or so + shipping, not a bad deal in my opinion.
Also I got a 100% positive feedback on ebay, so why I would want to ruin it, the description would be very accurate stating my problem and pictures would be added, any buyer will know exactly what he/she would be buying.
Ebay is a bigger market than my friends or family.
