Spit still the best

I’ve used several mask defoggers over the years, but find that spit still works the best especially if I rub saliva in the mask AFTER I’ve rinsed it in prep for the next time I get wet. So even if I forget to spit in the mask prior to a following dive, the surfactant nature of built-up saliva still prevents fogging. Amazing but true. A little on the gross side, but spit is effective, free, and conveniently available.

Mine works for me but I know a few divers that theirs doesn’t work for them. It maybe their diet or improper mask prep. They won’t let me spit in their masks.
