Defog Your Dive Mask for Good

There can be nothing worse during your Maui vacation than scuba diving or snorkeling with a foggy dive mask! It’s true, a comfortable and well-prepared dive mask is essential to your ocean experience. It is also safer for everyone around you. Unfortunately, when your lenses are full of fog, it blocks your view of the Maui sea life, and you cannot see hand signals from your dive buddy. Learn how to prepare your dive mask and save yourself the frustration.

There are a few methods that divers have long touted as the best way to prepare a new mask for diving. Most will tell you that toothpaste is a magic cure. While regular white toothpaste is helpful (NOT the gel kind!), there is an additional step that will defog your new dive mask for good.

3 Tips to Defog Your Scuba Mask

Tip 1: Choose the Right Mask

Before you even think about needing to defog your lenses, you first need a suitable dive mask. When shopping around, it is essential to try a variety of brands and skirt sizes. Every face is different, so scuba manufacturers make many types of dive masks at various price points. Pro-tip, don’t buy the cheapest or most expensive scuba mask.

Banyan Tree Divers recommends the Scuba Pro Spectra Mini for small faces! After trying different brands for smaller faces, this Scuba Pro mask is top of the list for its comfort, fit, and price.

When testing a mask, you will want to hold it up to your face, inhale through your nose and see if it sticks. If you get a good seal and like the mask skirt’s feel, you can try it on and make sure it is easily adjustable. Whether you buy a clear skirt mask or a black skirt mask is purely based on personal preference. Black skirt masks tend to cut the sun’s glare, which is helpful for underwater photographers. A good dive mask with a soft silicone skirt should cost $75 to $100.

Step 2: Dive Mask Burning

All new tempered glass lenses have a factory layer of protective silicone that causes each lens to fog when exposed to heat, such as heat from your face. Do not attempt to burn a mask with plastic lenses (#commonsense) on a side note! By removing that silicone layer with a lighter, you will permanently set up your scuba mask for success.

People out there will tell you not to attempt to defog your mask with a lighter, and it comes down to how comfortable you are with handling fire. So kids, please have a grown-up complete this step for you! As a dive instructor who has to replace her mask every few years and has prepared many dive masks, I can attest that this method works correctly.

Dive Mask Lens Burning Tips:

  1. NEVER burn plastic or prescription lenses. Dive mask lens burning applies only to glass.
  2. Do NOT burn the outside lens of your scuba mask. Instead, only use the flame on the inside of each lens.
  3. Hold the flame to the glass only while always staying away from the silicone skirt.
  4. Burn the glass until it turns black to remove the original factory protective coating.
  5. Be careful not to burn yourself. The lighter gets very hot, so take a break every 5 to 10 seconds.

Remember, after burning your scuba mask, each lens gets very hot. Therefore, it would be best to let the glass cool down before moving on to Step 3. Be careful here; glass tends to break when exposed to sudden changes in temperature!

Step 3: Toothpaste Rubbing

Use regular white toothpaste to rub on each burnt lens. The abrasive properties in the toothpaste will help remove the remaining factory coating. Rub this around for a good couple of minutes. Some will say you can set yourself aside for an hour before rinsing if you have the time. However, I am paranoid about leaving the burnt black matter in my mask and usually rinse it right away. I have never had an issue with this.

Hold your mask under lukewarm water and rinse with baby shampoo to not leave any soapy residue that could burn your eyes later. If you managed to get any of the burnt mixtures into the sides of your scuba diving mask, then you might need high-pressure water to remove them. Naturally, this burning method is more aesthetically pleasing for black skirt masks. However, sometimes it is harder to remove all of the black residues from transparent silicone masks. Consider this when purchasing your favorite scuba mask.

Once you have thoroughly rinsed your mask, it is ready for scuba diving! However, please note that it will still be necessary to defog your scuba mask with one of the following methods before you go diving:

Overall Defog Tips:

  1. Spit on each lens and rub it in! Scuba divers say, “the greener, the cleaner, whiter, the brighter.”
  2. Rub baby shampoo on each lens. Our dive shop uses this method because baby shampoo ensures no tears! We prepare a mixture of baby shampoo and water for divers to use before entering the water. It is essential to rub the mixture onto each lens vigorously.
  3. Spray store-bought anti-fog on each lens. You can purchase small bottles of defogging solutions from any Maui dive shop. They are often little enough to fit in a BCD pocket and handy to defog again on the surface before your descent.

Final Thought

A proper fitting and well-prepared dive mask is the most critical piece of dive equipment. Take the time to prepare your new scuba mask, and you will have countless enjoyable dives ahead. Always protect your dive mask by securing it before entering the ocean, and remember that once you put it on, leave it on your face.

Cheers and HAPPY DIVING!
