If fog develops on your swimming goggles, it can obscure your vision and prevent you from not only seeing where you're going, but also noticing other swimmers and obstacles in the water. This can create a potentially hazardous situation. Fog develops when your warm skin and evaporated sweat cause the air inside the goggles to become warmer than the outside air, allowing condensation to build-up on the inner surface of each lens. Dirt particles from eyelashes and oils from fingers can also contribute to fog. Stay safe while swimming by learning how to defog your goggles.

Shampoo or Dish Soap

    Step 1

    Add a dab of baby shampoo or dish soap and clear water to a soft, clean cloth.

    Step 2

    Rub the cloth gently over both the left and right lens to thoroughly clean them.

    Step 3

    Rinse the goggles well under clear water until the soap is removed.

    Step 4

    Dry the goggles with a clean cloth. Putting the goggles back on while they're damp can cause the fog to return.


    Step 1

    Spit directly into both the right and left lens. Make sure there's enough spit to complete cover the surfaces.

    Step 2

    Rub the saliva gently and directly onto the plastic. Avoid using your fingernails to prevent scratches.

    Step 3

    Rinse the saliva off your goggles with clean water. Don't rinse the goggles in pool water because the chlorine may burn your eyes.

    Step 4

    Dry the goggles completely with a clean cloth before putting them back on.
