foggy goggles

Maybe your spit is too watered down? I know that sounds gross but it is kind of in line with your statement that maybe its not the right anti-fog ratio. Don't think spit would work if you just took a big ol' drink of water. Of course, don't need to snort up a big slimer to make it work either...don't think you would be able to see through that any better.

On a less disgusting note...I have had best luck in races by not getting them wet in the first place. I find that if I put them on my face dry then there is nothing inside the goggles to fog up. That is of course if you follow the rule of no crying in triathlons!

Works well for me on all my eyewear/.

Thanks everyone!  Looks like spit is the overwhelming recommendation - I'll give it a try this weekend and see if i have defogger worthy spit - lol

if not, i'll move onto the baby shampoo, new goggles, and or professional defogging stuff

water needs something to condense on to form fog, so dirty lenses fog the worst.  Anti fog lenses actually have a very rough surface, so that water is sucked into the cracks, forming a thin film of water on the surface.  Fog drops will simply combine with the water surface instead of forming fog drops.  When that rough surface fills with crud (namely oil) fog will form.

Anti-fog stuff (and spit) form a thin hydrophobic (water repelling) layer that keeps fog away.

You can get a similar result (what I do) by washing (scrubbing) the lenses really well with baby shampoo (to remove the oils and crud) then rinsing really well.  The secret is to not touch the inside of the lens at all fith a bare finger (after beginning to rinse) and to store them in the hard plastic case they came in.  You can use any soap (you are rinsing it all out), but baby shampoo won't burn if some happens to stick in the gasket.  Oh yea, and if you can, don't dunk the goggles in the water before putting them on (if they are clean).  Just wet the gasket, or your face, to get the seal, put them on, then jump in the water.  If there's not a lot of water in there already, there won't be much to make fog.
