There is nothing worse than starting a dive, and a few minutes in your mask starts to fog up. Once you’ve underwater all you can do to clear the fog is adding some water, flushing it over the lenses and then clear your mask.
Here are a few tips you can use on land to prevent you mask from fogging before a dive.
1. Make sure if your mask is new that you use toothpaste and to remove the factories silicone coating. The coating on the inside of the lens is there to protect against scratches during manufacturing but should be removed before you dive. Rub a non gel toothpaste on the inside of the lens and rinse with fresh water before you dive.
2. There are several brands which sell anti-fog liquids, pick up a bottle of gel or liquid drops from your local dive shop and apply them to the inside of your dive mask before your dive. Put a few drops of the defogging liquid in the mask, rub it around with a finger, and rinse briefly with fresh water. Remember to leave a thin layer of the defogging agent inside the mask, so do not rub out the defog when rinsing the mask.
3. Spit is the tried and tested anti-fog device of many divers. This method works best right before a dive, spit in your mask and rub it around with your fingers. Rinse your mask before putting it on, and try not to let the mask dry to much before you enter the water.
4. Baby shampoo, bring a bottle of baby shampoo with you when you dive and use it on the inside of your mask before a dive and remember to rinse the mask before use.
