How to Defog Swim Goggles

How to Defog Swim Goggles
Foggy goggles are a nuisance in the sport of swimming, perhaps second only to water in the ear. For competitive swimming, in particular, you need all the clarity you can get to see when you are approaching the wall. Defogging your swim goggles is a good preventive measure before jumping into the pool or while swimming. Just follow these steps to ensure a clear view when under water.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:
  • Swim goggles Toothpaste Toothbrush Defog spray Dishwashing liquid soap
  • Swim goggles
  • Toothpaste
  • Toothbrush
  • Defog spray
  • Dishwashing liquid soap
Step 1
Wash brand-new goggles with toothpaste to remove any silicon film from the rubber lens housing, which can cause fogging. Scrub gently with an old toothbrush, then rinse with cold water.
Step 2
Lick the inside of the goggle lenses, then rinse to defog swim goggles. Saliva acts as a natural barrier between humidity and the lens to prevent fogging. Don't touch the inside of the lens with your fingertips, which contain oils that will remove or reduce the benefit of the saliva.
Step 3
If licking or spitting into your goggles is unacceptable, lightly spray the inside of the goggle lenses with a defogger available at scuba dive shops and some sporting goods stores.
Step 4
When spit isn't the solution and defogger spray is unavailable, add one drop of liquid dishwashing soap to each lens, and turn the goggles so the liquid spreads around the inside surface. Use a paper towel to spread the soap around, then rinse thoroughly in cold water to prevent eye irritation. A small residual amount of the soap will remain to defog your goggles.
Step 5
Exhale through your mouth only while swimming if the goggles extend over your nose, such as a dive mask. Exhaled air contains water moisture--humidity--which will quickly fog your goggles.

Tips & Warnings

 
Carry a small travel-size bottle of dishwashing soap in your swim bag when you go to the pool. Remember to rinse well to aovid stinging.
