5 Best Ways To Prevent Scuba Mask from Fogging


Many things can ruin your dive, and one of them would be a foggy mask. It affects your vision, concentration, and comfort, among other things. You won’t be able to appreciate the beauty of the marine diversity that unfolds in front of you!

The good thing is that you can always choose to wear an anti-fog mask, which has a special kind of coating and material that will allow it to resist fogging. Consequently, there are also simple measures that can be undertaken to prevent scuba mask fogging.

Whether you are using a scuba mask or a freediving mask, among others, the ways to get rid of fogging will be the same.

The next time you go for a dive, make sure that fogging is not a problem you have to deal with. Keep on reading and learn from some of the tips we will share!

1. Saliva

Oldie but a goldie – this is perhaps the best way to describe this trick. Not just for scuba masks, the same can be effective when it comes to preventing goggles from fogging.

All that you have to do is to spit directly in the mask and spread the saliva using your finger, making sure that the entire area is covered. Then, rinse it with water.

So, how does saliva work to prevent fogging? Well, it acts as a surfactant or as a wetting agent that will be responsible for minimizing water’s surface traction. This means that the water that forms as a result of evaporation will not form in clumps. They will break down into huge droplets and will slide smoothly on the mask. Basically, your saliva will make it harder for the water droplets to cling to the surface, making it a great treatment for the anti-fog mask.

However, take note that this technique will only be effective if you do it before the dive. If it is done hours before the dive, this won’t work as it will dry and will only cause the mask to blur.

2. Toothpaste

As the use of saliva, using toothpaste for the anti-fog mask is another trick that has been around for a long time and can prove to be highly effective. It will also work to stop snorkel mask from fogging, not just scuba diving masks.

To do this, simply squirt toothpaste directly on the lens of the mask. Using your finger, rub it around the lens, making sure that all areas are covered. You can also use a soft cloth. In some cases, it would be best if you leave the toothpaste on the mask overnight and wash it the next morning.

The right choice of toothpaste will be critical for this trick to be effective. You should avoid toothpaste that is overly abrasive as this might scratch the mask. Whitening toothpaste is best to be avoided as they frequently have granules that can scratch the glass. The toothpaste should be free of bleaching agents.

Test this trick before you use the mask. All that you have to do is to breathe directly on the glass and see if it still fogs. If it did not work, you might have to repeat the process.

3. Commercial Defoggers


Some commercial defogging agents can help. They are in small handy bottles and you can easily pack one. It is one of the items that should be on your scuba diving checklist. Most of these products will leave a film that will last even after multiple dives.

Different manufacturers may have different instructions on how to use their defogging agent. In the case of most products, all that you have to do is to add a few drops directly to the mask. Rub it around using your finger and rinse with fresh water.

Take note, you should not rub with too much pressure. You need to leave a thin layer of the defogging agent, which will act as a surfactant to prevent the mask from fogging. When you are rinsing the mask, avoid rubbing the mask so that a thin layer of invisible film will be left on the glass.

4. Baby Shampoo

If you want an anti-fog mask, another thing that you can do is to use baby shampoo. A lot of divers always carry a small bottle that contains watered-down shampoo in their dive bag, making it easy to rinse a mask when they are on a boat.

The process will be similar to those that have been mentioned above. Add a few drops directly on the lens, rub it, and immediately rinse.

Now, you might ask why a baby shampoo is better than an adult shampoo. The secret lies in the ingredients that are used. Baby shampoos are generally gentler since they do not contain harsh chemicals. They are hypoallergenic. Hence, they will not irritate when they get contact in the eyes when you are already diving.

5. Change your Habits

One of the most important is to avoid touching the mask, whether before the dive or during the dive. Especially if you have just applied a defogging agent, touching the glass will make it prone to fogging. This can cause oils from your hand to transfer to the lens.

It is also critical to learn tips for breathing better when you are scuba diving. You should not breathe out of your nose. If you exhale through the nose, this is one of the leading causes of scuba mask fogging. It is also one of the reasons why your mask leaks. It might take a while, but with consistent practice, you will find it easy to breathe from the scuba regulator instead of your nose.

Another thing that will help is to ensure the right fit of the mask. If it is too tight, you will most probably end up being uncomfortable. On the other hand, if it is too loose, moisture can get inside. This will lead to condensation, and the result is that your mask will end up being foggy. As you wear the mask, check it and be sure that no hair strands are trapped in the skirt, which will prevent the mask from leaking.

Care and maintenance of your diving mask are necessary. See to it that it is cleaned or rinsed right after every dive. When not used, the masks should be stored properly. Ideally, you should wrap it with a cloth or put it in a clean bag. This will prevent external elements from ruining the lens and making it prone to fogging. Also, it will help to wash it with warm and soapy water after a dive to remove sunscreen residue that can contribute to fogging.

If you would like to be prepared, it will also be a good idea to have a spare mask that is attached to your scuba BCD.
