How to Keep Your Snorkel Mask From Fogging Up

            Pesky fog build-up ruins once-in-a-lifetime experiences out at sea. Why go through the trouble of equalizing and heading deep if you can’t see underwater? Preparation is critical to avoid this situation. Don’t worry. There are some quick and easy solutions to tackle foggy lenses!

How Does Mask Condensation Form?

            Mask fog occurs when the outside temperature is lower than inside of the mask. This process is common and almost unavoidable when transitioning from the warmth above water to colder temperatures underwater.

Here are three ways to prevent your snorkel or scuba mask from fogging up: 


Seavenger Anti-Fog Hanalei Snorkel Mask

            The easiest solution to foggy lenses is an Anti-Fog Mask. Why aren't anti-fog masks an industry standard, you might ask? Anti-fog masks are few and far between! Here at Seavenger, we have developed an Anti-Fog Twin Lens mask included in all the Hanalei Snorkel Sets for adults and kids. The way it works is simple but difficult to source. A durable anti-fog film on the tempered glass lens provides a permanent anti-fog effect.

            As you can see in the image above, there is a lining throughout the lens; this is the anti-fog film. It’s very easy to use. When you receive your mask, simply remove the protective layer. To maintain the anti-fog effect, rinse the lens with cool fresh water before and after each use. This step is critical to the effectiveness of the anti-fog film. Otherwise, you’re good to go 24/7! This method is far superior to any other anti-fog solution, as mentioned above.

Seavenger Anti-Fog Spray for Snorkel and Scuba Masks

            Spray & Go! Anti-Fog sprays are very popular and similar, if not identical, to standard sprays for glasses like the ones you’d find at your local pharmacy. The Seavenger Anti-Fog Spray is made for ocean use and can achieve fogless views underwater. All you have to do is spray the formula onto your clean lens two times. Then gently rub in the liquid formula with a soft cloth. After the product is evenly distributed and buffed in, rinse with fresh water - do not use salt water from the sea! Your lens should look squeaky clean. Otherwise, repeat the steps until it is. To retain the anti-fog effect, repeat this process for every use.


  1. Clean & Dry Your Mask 
  2. Spray 2x Directly onto the Lens 
  3. Rub In Using A Soft Cloth 
  4. Rinse With Fresh Water
  5. Dive Deep!

Seavenger Lens Cleaner and Anti-Fog Gel for Snorkel and Scuba Masks

          Anti-Fog Gels use the barrier method to get clear views underwater. With Seavenger’s Lens Cleaning Anti-Fog Gel, you clean and anti-fog your dive mask in an easy 2-for-1 process. This formula variation is intended to clean your lens thoroughly, but a mask should already be somewhat clean, free of sand and saltwater. Consider it a final varnish that wears off over time. The application process is straightforward. Start with a clean mask, then add one drop of gel to each lens. A little goes a long way! Generously coat the entire surface and rub in the formula using your fingertips. Then, rinse with fresh water at least two times. With gel formula, you want to leave a thin layer of gel on the mask. Otherwise, the anti-fog effect won’t work. Consider this factor when rinsing. 


  1. Clean & Dry Your Mask
  2. Add 1 Drop To Each Lens 
  3. Rub Thoroughly Using Your Fingertips 
  4. Rinse With Fresh Water 2x
  5. Leave a Thin Gel Coating on the Lens
  6. You’re Ready to Head Underwater!

         Although anti-fog formulas are a great option, there are a few drawbacks. Once out at sea, you risk not having freshwater or a soft cloth readily available. While defogging the mask, you might end up scratching your lens with a few pesky grains of sand. 

         Consider the environmental factors. Seavenger’s formulas are non-toxic, alcohol-free and biodegradable. But not every anti-fog formula is created equal. At Seavenger, we recommend choosing an anti-fog additive that is safe for human use and environmentally friendly to the sea. Our most significant responsibility is to the ocean we are exploring, after all! 

         Anti-fog masks are more effective and efficient- the future of watersports gear. We encourage you to venture deep and try out all of these methods yourself. Let us know what you think.
