How do de-fog goggles

[socalnano24]

If they are glass goggles which are new, they will have a factory film on them. Without removing this film they will always fog a lil bit.
Rub them with a your finger with some toothpaste. then rinse them out with water really well and finally with a soft cloth.
Then as everyone else said, when you are using em. Spit in it and rub it around with your finger, then rinse it real briefly to get the spit out(It will leave a light film).
If you encounter kelp, it is a naturally defogger as well, just rub it on.

I totally forgot...
One3 of the tour "captains" had a bucket of water to dip your goggles in, but he added a little bit of johnson's baby shampoo, that way if it did get in your eyes it was still safe.
Seemed to work, but I can only judge from watching others, as I had my drops.
