The Science Behind Why Divers’ Masks Fog Up and How to Prevent It
Have you ever noticed that your mask fogs up more on a cold day? And have you ever wondered why? It turns out that the answer has to do with the temperature of your breath and the water vapor the breath contains. Divers’ masks fog up because your car windows fog up on a cold day. When you breathe, the warm air from your lungs meets the cold glass of the mask, and this temperature difference causes water vapour to condense on the surface of the glass. You can rub the anti-fog liquid on the inside of the mask before diving. The defog products forms a thin film that helps to prevent water droplets from condensing on the surface of the glass. By following a few simple tips, you can keep your mask fog-free and enjoy a clear view of the underwater world.
A New Dive Mask Keeps Fogging
No matter the mask’s quality, a thin layer of silicone oil condenses on the glass lens of your new dive mask during the manufacturing process. This oil will cause rapid fogging that is resistant to conventional anti-fogging measures and must be removed.
Cleaning your new mask is necessary to reduce the chance of your brand-new mask fogging. Commercial mask cleaning materials are on the market, but toothpaste is just as good and a much cheaper alternative.
Spread toothpaste on the lenses inside your mask and vigorously rub for at least one minute using either a soft-bristled toothbrush or your finger. Then, wash out your mask with cold tap water. Once you are done, assess it by breathing into your mask and seeing if it fogs in any area. You may have to repeat this method once or twice; if correctly done, it will be the best way to prevent a mask from fogging long term.
