Best Anti-Fog for tec divers

[Doppler]

I use cheap baby shampoo too. Have a dilute solution in a spray bottle (that often gets left in the back of my truck, accidently) and also use it to help to put on wet-gloves.

I use baby shampoo most of the time, but in a pinch I will just spit in it (mask that is). I have done 5 hours dives with no fogging issues with babby both methods.

I have found that if my mask does start fogging and I have to clear it more than once, that if I take it off and rub the inside of the mask with my fingertip very ruggedly it solves the problem for the rest of the dive.

I'll have to try your second suggestion. I use johnson and johnson baby shampoo diluted with water in spray bottle and it works great 9 times out of 10... but when on those longer dives where i have to clear a few times, and it gets washed out, it starts fogging a lot which can get miserable.

Spit.

For my most uber-tec dives, I spit twice for the sake of redundancy.

can be dangerous as well.

everyone doing long tech dives should clean their masks periodically, not just defog it, but scrub it out really well.
almost killed me once...

I actually died one time because of a fogged up mask; but luckily my buddies were able to bring me to the surface and clean things up for me and everything turned out OK.

i was being serious. i was having a very bad time because of a mask fogging

I clean my backup mask before every dive, too. A lot of folks forget to do that.

10-1 solution of baby shampoo and water. Works as an anti-fog and I spray it on my drysuit seals before I don the suit as a mild lubricant.

Whoops, sorry, mate. I obviously figured you were being flip.

Big +1!

My tec instructor taught me a valuable lesson on this...my backup mask hadn't been cleaned in months. It was a miserable dive, to say the least. Fortunately it was a training dive and I wasn't in any real danger because of it.
