How to Prevent Fogging of Diving Mask?

All divers have at one time or another encountered the problem of mask fogging, and it can be really annoying. In this blog post, we'll discuss what causes mask fogging and how to prevent it. So read on to become a smarter, more prepared diver!

Have you noticed that your mask fogs up more on colder days? Have you ever wondered why? The answer, it turns out, has to do with the temperature of your breath and the water vapor it contains. A diver's mask fogs up because your car windows fog up in cold weather. When you breathe in, warm air from your lungs meets the cold glass of the mask, and this temperature difference causes water vapor to condense on the glass surface.

Anti-fog fluid can be rubbed on the inside of the mask before diving. Defogging products form a thin film that helps prevent water droplets from condensing on the glass surface. By following a few simple tips, you can keep your mask fog-free and enjoy a clear view of the underwater world.

Regardless of the quality of the mask, a thin film of silicone oil will form on the glass lens of a new diving mask during the manufacturing process. This oil causes rapid fogging that cannot be resisted by conventional anti-fog measures and must be removed.

Cleaning new masks is a must to reduce the chance of fogging a brand-new mask. There are commercial mask cleaning materials on the market, but toothpaste works just as well and is less expensive.

Apply toothpaste to the lenses inside the mask and rub vigorously with a soft-bristled toothbrush or your fingers for at least a minute. Then, wash the mask with cold running water. Once done, evaluate it by breathing into the mask and seeing if it fogs up in any areas. You may need to repeat this method once or twice; if done correctly, this will be the best way to prevent long-term fogging of the mask.

A toothpaste treatment on a new mask is essential, but if you want to keep your dive mask fog-free, you must also use an anti-fog product on every dive.

There are a variety of sprays, gels, and drops designed specifically for defogging snorkels and scuba diving masks. Apply enough product to the lenses of the mask to cover them, shake it side to side, and rinse the mask once with salt or freshwater before diving. These usually cost around $10 for a 40ml bottle, but a bottle lasts a long time.

A good quality baby shampoo will do the same, but won't cause any irritation if there is the residue after rinsing. The only downside to baby shampoo is the size of the bottle; it won't fit in your BC pocket and you'll have to make an extra trip back to shore. However, the few dollars you save on baby shampoo isn't worth the inconvenience.

The other option is spit, and while it's free and just as effective as the drops, it can cause mold to grow in your mask, so it'll cost more over time.

If your diving mask is still fogging up, two small changes to your diving habits can make a huge difference. First, avoid touching the inside of your mask's lenses, especially after using a defogging product. Touching your mask will transfer oils into it, rendering the demister ineffective. Second, don't exhale through your nose. It may take time to get used to inhaling and exhaling through the mouth only, but exhaling through the nose is a common cause of mask fogging.

All divers have mask lens fogging at some point, but by following the procedures above, the problem can prevent their mask from fogging up and they can enjoy every dive to the fullest.

Foggy diving masks can be really annoying, but by following the simple steps in this blog post, you can minimize the chances of that happening. By understanding what causes mask fogging and how to prevent it, you'll be able to keep your mask clear and focus on the amazing underwater world that awaits you. So be sure to buy a quality mask and treat it properly so you can enjoy every dive!
