Diving - How to Remove the Fog in Your Snorkel Mask

At some point during snorkeling you will always get fog onto your mask. To prevent the development of fog you need to treat your mask.
The glass of a mask is always covered by a silicon film and this is what is responsible for the appearing fog.
First eliminate this when you buy a new mask. Take some toothpaste, put in your mask and clean it with a small sponge. It's fast and easy, say bye bye to the fog!
