Instructions

  1. 1

    Heat 1 quart of water to a temperature that is hot, but not so hot that you cannot touch it. Water starts to get uncomfortable to the touch around 50 degrees Celsius (122 degrees Fahrenheit). If your water heater is set high enough, you can use the hot water from your hot water faucet. Otherwise, you can heat the water in a sauce pan or in a heat-resistant measuring cup in the microwave. If you have a submersible thermometer to test the heated water, that isn't a bad idea.

  2. 2

    When the 1 quart of water is heated, add 88.7ml of vinegar and stir.

  3. 3

    Dip your lint-free cloth (such as linen) into the solution, squeeze out the excess water, and rub the surface making circular motions.

  4. 4

    Allow the solution to dry. The surface should now stay fog-free. If the surface fogs again after 3 or 4 weeks , make a new batch of anti-fog solution and reapply.

Tips and warnings

  • If you don't have time to make your own solution, you can also try using baby shampoo or toothpaste, which many swimmers use to keep their goggles from fogging.
  • Be careful when handling water heated in a microwave. Because items heated in microwaves heat unevenly, part of the water might be cool enough to touch while another part of the water (or measuring cup) might be hot enough to burn you.
