Defogging a swim mask is easy. You just spit into the face plate. It's the first thing kids learn to do when they get a mask, fins and snorkel set. They never seem to forget it. This old-fashioned method works just fine, and is a quick solution for divers who don't have their defoggers handy before they dip below the surface.
Here's a quick reminder on how to defog your mask:
- Dip the face plate in the water, then shake the water out.
- Spit into the face plate and rub the spit on the glass with your fingers.
- Dip the face plate again and empty the water. You are ready to dive.
