If you’re a scuba diver, you know that nothing can ruin an underwater adventure faster than a foggy dive mask. Fogging masks are not only annoying, but can also make it difficult to see and navigate the depths of the ocean.

Luckily, there are several steps you can take to help keep your dive mask from fogging up and allow you to enjoy crystal clear visibility while exploring beneath the waves. In this blog post, we’ll discuss some top tips for keeping your dive mask free of fog so that you have maximum enjoyment on all your dives!

Why Does it Happen?

How to Keep A Dive Mask from Fogging Up

Understanding why dive masks tend to fog up is an important step towards preventing it. Fog forms when the air inside a dive mask gets warmed from bodily heat and condenses on the cooler lens surface, causing tiny droplets of liquid water.

To prevent fogging, determine what type of dive mask you are using then consider specific steps such as applying a small amount of toothpaste or baby shampoo on the lenses before diving as this creates a barrier that will keep the lenses from fogging up during your dive.

Specially treated defogging products may also be used as an extra precaution to protect your visibility underwater. Taking these steps can be very helpful in ensuring you have a fog-free diving experience!

How Can I Prevent it?

Preventing your dive mask from fogging up is a great way to ensure an enjoyable and safe dive experience. There are a few simple steps you can take to reduce the likelihood of fogging. First, always wash your mask in warm fresh water before and after each dive, preventing dirt build-up which can cause fogging.

Next, rub a generous amount of anti-fog gel across the lenses when they’re damp and the gel won’t dilute away. Lastly, consider purchasing a silicone neoprene strap – it is more comfortable than the traditional rubber option and allows for greater air circulation, reducing trapped moisture that can cause fogging.

These easy tips can help you avoid having an obscured view while scuba diving, allowing you to appreciate the majestic sights hiding beneath the waves.

How To Keep A Dive Mask From Fogging Up: Tips Before Wearing it For The First Time

How to Keep A Dive Mask from Fogging Up

Following are some of the ways to keep a dive mask from fogging up:

Use Toothpaste

One of these methods is to use toothpaste to clean and defog the mask’s lens. This should be done with a soft cloth and gently applied onto the lens in a circular motion.

Heat the Glass

Keeping a dive mask from fogging up should be one of the first steps for any diver before wearing it for the first time. To do this, divers can heat up the glass with lukewarm water to encourage better adhesion of the anti-fog coating. This in turn helps create a stronger barrier against condensation and therefore less fogging.

Use anti-fog products

Wearing a dive mask while snorkelling or scuba diving is essential to the underwater experience, but an issue that many underwater enthusiasts may face is fogging.  When you can keep your dive mask clear and fog-free, it allows a greater diving experience with unhindered visibility.

To make these possible, anti-fog products are an effective option that can help prevent the build up of condensation on the lenses of the mask. The first step when wearing a dive mask for the first time is to clean it well with warm water and soap in order to remove any oily residue.

Then applying an anti-fog solution will form a protective barrier and ensure maximum clarity when entering the water. Additionally, using saliva as a pre-dive treatment can also reduce fogginess and improve visibility. Whatever method is chosen, adhering to proper usage techniques of anti-fog products can provide enhanced underwater experiences for divers of all levels.

How to Prevent Dive Mask Fogging: Tips Before Every Dive

How to Keep A Dive Mask from Fogging Up

Fogging up dive masks can be one of the biggest pet peeves experienced by divers.  Fortunately, there are a few things you can do before every dive to ensure your mask will stay clear.  To begin, rinse your mask with fresh water prior to entering the water – this helps reduce any oils that may cause fogging.  

Secondly, defer to an anti-fog solution like a gel or liquid spray for an added layer of protection against the build up of fog on the inner lens of the dive mask; these solutions work best if applied just before entering the water.  

Finally, ensure that your dive mask fits properly as gaps between skin and silicone can contribute to fogging issues by retaining moisture.  Enjoy your next dive with a crystal-clear view and follow these steps!

Spit in It

Spit has been a beloved remedy to help keep dive masks from fogging up for generations. It is the simplest and oldest form of anti-fogging; however, it can be ineffective if not done properly. To properly use spit to keep a dive mask from fogging up, start by making sure you have a good seal between your face and the mask.

Then submerge the mask in water before adding a few drops of spit and sloshing them around inside the mask. Finally, you will want to rinse off the excess saliva with clean water before fully putting on your dive mask so you don’t have an icky taste in your mouth during your dive! Following this recipe ensures that you can enjoy an uninterrupted aquatic outing with minimal interference from foggy lenses.

Wash Them with Dishwashing Detergent

Before every dive, it’s important to prepare your dive mask properly. Doing so not only ensures your glasses won’t fog up, but also makes sure that you have the best visibility underwater. It is recommended to clean the surface of your mask with lukewarm water and dishwashing detergent, then gently rinse off the detergent with clean water.

Afterward, you can use an anti-fog treatment on both sides of the glass for maximum protection against fogging up. Following these easy steps before each dive will make sure you remain safe and comfortable once you’re in the water!

Use Baby Shampoo

Baby shampoo is an easy, cost-effective way to keep a dive mask from fogging up. Just keep a small bottle of baby shampoo with you on the boat and before entering the water, rub a drop or two onto the inside of your mask, spread the liquid around and rinse it off.

This will ensure your mask won’t fog up when you start diving. With just this simple step, you can now focus on what’s in front of you rather than struggling with visibility underwater. Don’t forget; always store and carry your mask with clean hands to ensure optimal performance from your dive gear!

Use Your Knowledge as a Diver

Knowledge is a diver’s best friend, and this knowledge should be used to make every dive a safe and enjoyable experience. One of the most common problems that divers face is fogging up of the dive mask. Fortunately, this can be easily prevented with a few simple tips. Before diving, I always rinse my dive mask with distilled or purified water and then rub it inside-out with anti-fog gel or liquid – this helps keep the glass from fogging up as I continue to descend underwater.

Additionally, as I get closer to the waters surface, I exhale slowly through my nose in order to equalize the pressure within my mask. This is an easy trick that can help keep me safe and comfortable while diving!

By taking some easy precautionary steps before and during every dive, you can maintain a clear vision.  An important tip to remember is to not spit directly into the mask itself as this will cause the inside of the mask to be sticky and promotes fogging.

Additionally, many divers like to apply anti-fog treated drops or spray on microfiber cloths to the inside of their masks beforehand which helps them stay clear throughout their dives. With these tips in mind and with continued practice, you can maintain clear vision for your dives!


If you’re interested in preventative methods, there are a few things you can do before putting on your dive mask for the first time. You can apply toothpaste or heat the glass. If those don’t work, you might have to purchase an anti-fog product specifically designed for keeping lenses clear.  Before every dive, even if you’ve taken care of your lenses beforehand, it’s important to remember a few key things that will help keep them from fogging up.

Spitting in your mask and washing it with dishwashing detergent or baby shampoo are two guaranteed ways to keep your vision unobstructed underwater. And as always, being a knowledgeable diver who understands how to take proper care of both yourself and your gear is one of the best ways to avoid any minor issues like fogged-up glasses.
