How to Avoid a Mask Fogging Fiasco while Snorkeling

There’s nothing worse than going on a once in a lifetime snorkeling trip, only to find your mask constantly fogs. A fogging mask can make any snorkeling experience complicated, and brand new masks are prone to fogging. If you follow these tips, you’re bound to have a fog free and pleasant snorkeling experience.

Clean Your Mask

After you have tested the fit of your mask and determined this mask is the perfect one for you, the first thing you should do is clean it. Just because it is new doesn’t mean prep is not needed! The best way to clean a new mask is with a mild abrasive, such as Sea Buff or plain white toothpaste. These cleaners will remove any film that may be on the lenses from production, which can cause fogging.

Apply Anti-Fog Gel

Once cleaned, you can store it in a cool, dry place until you’re on the way to your snorkeling site. When you have arrived at the site and are getting ready to dive in, prep the mask with an anti-fogging solution. There are many different types of anti-fog gel for masks. We have found Sea Gold Anti-Fogging Gel from M Essentials to work best for us, but feel free to try different types. A tried and true method for anti-fogging that has been around forever is spit! It may not be the most sanitary thing, but there are plenty of divers that swear by the spit method.

Be Aware of How You’re Snorkeling

There are a few things you can do to limit fogging while snorkeling. It may seem natural to inhale through your mouth and exhale through your nose, but fight this urge! Exhaling through your nose causes a temperature difference between the air inside the mask and the water outside, causing the mask to fog. Focus on breathing in and out through your mouth, and this should help keep your experience fog-free.

Clean It Again!

After your experience is done, make sure to clean your gear after every use. This prevents things like sand, sunscreen, face oil, and bacteria from stubbornly building up on the mask which can cause fogging the next time you use the product.
