Homemade Anti-Fog for SCUBA Masks

Before fitting your SCUBA mask, apply two drops of anti-fog solution to prevent fog buildup.

SCUBA divers, swimmers, mountain climbers and certain equipment operators rely on unimpaired vision to safely navigate. If fog collects on their masks or goggles, not only is it potentially dangerous, but it is also difficult to prevent the fog from immediately rebuilding. Fog also collects on windshields and bathroom mirrors when the temperature moves between hot and cold. Commercial anti-fog solutions do a fine job of preventing most fog accumulation, but it's easy to make a homemade anti-fog mixture for your SCUBA mask.
