Best Scuba Mask Anti-Fog Treatments

Scuba diving is a great way to spend a day. You get to see the world from a whole new perspective and enjoy observing creatures that can’t be seen anywhere else. But a foggy mask can quickly diminish the experience.

So before your next dive, check out our list of some of the best scuba mask anti-fog treatments to discover how you can keep your scuba mask fog free for your next dive.

Scuba Mask Anti Fog Treatments

Below is a list of our top anti-fog treatments, they are in no particular order as they all have their own pros and cons. Chances are that a solution that may work for you won’t work for someone else, therefore, we encourage you to try multiple treatments to find the one that is best for you.

Just Add Water Quick Spit

This anti-fog treatment is a spray that you apply to your mask before you dive. Because you can spray it on really quickly, it is much more convenient than some other anti-fog treatments on this list.

Whether your mask is wet or dry, this treatment will work like a gem, making it ideal for smaller expeditions. And you don’t just have to use it for your dive mask, as it can also be used for any other goggles you use, such as swim goggles or ski goggles when you aren’t diving.

This treatment is reasonably priced, and divers report that it lasts them a long time, sometimes even multiple dives! The bottle states that it contains over 200 squirts of product, meaning this could last you a year or longer.

The downsides? Well, you have to apply well in advance, almost 30 minutes, prior to your dive for the best results. It can be difficult for some people to remember this. Also, once you apply it, it’s best not to touch it…which can also be difficult for some people to remember.

Pros:

• Inexpensive
• Easy to apply
• Long-lasting
• Chemical free
• The small bottle makes it easy to take anywhere
• Wet or dry application
• Works for all types of goggles

Cons:

• Must be applied in advance
• The lens can’t be touched after application

Scuba Concepts 500 PSI Mask Anti-Fog

Similar to the Quick Spit, this anti-fog treatment is notoriously long-lasting, and many divers report one application can last for multiple dives in the same day. Unlike the Quick Spit, however, this anti-fog treatment is a gel that comes in a squeeze bottle.

While this makes application a bit more difficult, it does make it less likely to leak during travel and helps it to cling to the lens better, so you don’t have to be as careful where you touch after application.

You can’t be afraid to get your hands dirty when using this anti-fog treatment, though, as you will need to smear it on the mask rather than having the benefit of a convenient spray. You can apply it to your mask, whether it’s wet or dry.

Pros:

• Long-lasting
• Wet or dry application
• Less likely to leak
• Clings better than other treatments

Cons:

• Need to use your hand to apply
• Can leave a weird residue on your mask

McNett Sea Drops

McNett Sea Drops are the best 2-in-1 option as they are both an anti-fogging treatment as well as a cleaning solution for your scuba mask.

The sea drops come in a squeeze bottle and are in liquid form. The solution is non-toxic and alcohol-free and can be used with eyeglasses, sunglasses, and facemasks but not swimming goggles, so take note.

Unlike the previous anti-fog treatments, this one must be applied to a dry lens, making it not ideal if you are headed out for a long dive day and think you may need a couple of reapplications. You will also need to carry a clean rag to buff this liquid onto your scuba mask.

Also, note that this anti-fog treatment is only for one dive. You must clean your mask after each use otherwise, mold and algae could form. Additionally, allow this product to dry completely before you dive, as it can irritate your eyes.

(Note this product is sold by the GearAid brand in some countries however it is the same product).

Pros:

• Inexpensive
• For use with other types of glasses
• Cleans and keeps fog away

Cons:

• Not for swimming goggles
• Scuba mask must be cleaned between each application
• Can irritate your eyes if not dry
• Must be applied on a dry lens
• Should be applied with a clean rag

Cressi Anti-Fog Spray

Cressi Anti-fog spray is an alcohol-free solution that is specifically designed for those who find their eyes irritated by other anti-fog treatments. It’s the best of both worlds because you can choose how the liquid comes, whether you prefer a gel, spray, or even a wipe (for use with glasses).

The effects of this solution are long-lasting, and whether you pick the gel or the spray, know that one bottle will get you hundreds of applications, meaning you likely only need to purchase this product once a year. You can apply this product either wet or dry.

You’ll put a small amount on the lens, using your finger to spread it around. Afterward, you will rinse with a small amount of water to remove the solution but create a film. If you would rather not use your finger, you can buy the version of this product that comes with a sponge, allowing a more precise application.

Pros:

• Comes in many forms, you can find your favorite
• For use with goggles, masks, and glasses
• Inexpensive
• Long-lasting
• Wet or dry application
• Can be used for plastic or glass lenses

Cons:

• Must use your finger to apply unless you purchase the sponge version
• Lens must be rinsed after application

Happy Snorkel Mask Anti-Fog

Happy Snorkel Anti-Fog is the smallest treatment on our list at only 1.25oz, meaning it is the best for the diver who travels the world to follow seasonal sea temperatures. Don’t let that fool you, however, as this small bottle can last you up to 50 dives, meaning you won’t need to replenish mid-season.

This product is unique in that it is fragrance-free, making it the best choice for those with allergies or sensitive eyes. It is also biodegradable, which makes us happy as it is completely reef safe.

While this product is great for scuba or snorkeling masks, you can also use it for your swim goggles, so you may want to buy a couple of bottles. For use, squeeze a few drops on your mask and use your fingertips to rub. Then rinse in water to set. The solution will create a film that will keep the fog off your goggles and keep your vision crystal clear.

Pros:

• Small
• Reef safe
• Inexpensive
• Good for those will allergies

Cons:

• Must be applied before each dive
• Must be applied using fingers
• Must be applied on a dry mask, and the mask must be rinsed after

Stream2Sea Biodegradable Formula Mask Defog

Stream2Sea is the best choice for those worried about harming the environment with their mask defogger as it is non-toxic and reef friendly. Stream2Sea is safe for both plastic and glass scuba and snorkeling masks. It is also safe for swim goggles, glasses, and just about anything you can put over your eyes for vision purposes!

To use Stream2Sea, you’ll use the dropper bottle to place a few drops on the lens and rub with your finger. While this isn’t as easy as a spray application, it is still fairly simple to figure out as long as you don’t mind using your hands!

You do need to add a little water to rinse away the liquid before you put the mask on, but it can be sea or freshwater. Unlike any other product on this list, the packaging for this product is even eco-friendly as it is made out of sugarcane resins or recycled materials rather than being made out of plastic.

Stream2Sea doesn’t need to be re-applied after every use, and how often you need to reapply will depend on your preferences. Most users report that one application can last 2-3 underwater visits. Because it is impossible to reapply once you are underwater, we recommend planning to reapply every other use just to be on the safe side.

Pros:

• No plastic packaging
• Completely reef-safe
• May last multiple uses
• Inexpensive
• Easy application
• Safe for multiple surfaces

Cons:

• Need to use your finger and water for application
• Not the smallest bottle on our list

At Home Anti-Fog Treatments

Are you headed snorkeling tomorrow and don’t have time to order a product to keep your mask fog free? Don’t panic, as there are many home remedies you can employ to keep your vision crystal clear.

Toothpaste

Simply squirt a small amount of simple toothpaste (none of this confetti or whitening stuff) on your scuba mask and rub it around with your finger. Leave the toothpaste on the mask overnight, then wash away in the morning.

Note that you can use a rag instead of your finger, but ensure it isn’t abrasive enough to scratch the lens.

Flame

Use a lighter and run the flame over the inside of your scuba lens until it turns black. This is the flame burning the fog residue off. When the mask is completely black, the process is finished.

Allow the mask to cool, then wipe away the black with a soft cloth. You may need to repeat the process until the goggles no longer turn black.

NEVER attempt with plastic lenses, this trick only works with glass, and the flame must be kept away from the softer parts of the mask.

Baby Shampoo

Baby shampoo works much the same as the products you can purchase specifically for anti-fogging listed above. The only difference is that you might already have it on hand, saving you a trip to the store.

Squeeze a few drops on the lens and rub with your finger, then rinse the mask, allowing a film to develop. Don’t use regular shampoo as it could irritate your eyes and is likely not as biodegradable as baby shampoo is.

When Should You Apply Mask Anti-Fog Treatments?

Wondering when you should apply your mask anti-fog treatment? Well, for best results you should follow the instructions on the product you have chosen to use.

Some products require application before each and every dive, while others only need to be applied every few uses. For best results, we recommend getting into the habit of applying every single time, as otherwise you may get underwater only to find your scuba mask fogging!

For many of the at-home treatments, especially the flame treatment, this is a one time application, meaning it doesn’t ever need to be repeated if done correctly. If you are struggling with a foggy mask even after the flame treatment, it’s probably a good idea to pick up a liquid or gel anti-fog treatment to use when you dive. Sometimes the home remedies just aren’t the same as a product!

Anti-Fog Treatment FAQS

The best way to keep your scuba or snorkel mask from fogging up is putting a solution on the lens. There are several types of solutions to choose from and you may need to try a couple before you find the one that is right for you.

What Can You Put on a Face Shield to Keep it From Fogging Up?

Face shields are made of plastic, and generally, any anti-fog treatment on this list that is safe for plastic goggles is also safe for a face shield.
