Anti-Fog for Dive Masks Buying Guide

SCUBA and snorkel mask defoggers are relatively cheap and will save you from a lot of headaches and frustrations in the water. Some people argue that home remedies are just as effective, such as using diluted baby shampoo or rinsing the lens with your own spit. The former is not always reliable, and the latter some might find to be too gross for their liking.

Additionally, some mask defoggers double as a lens cleaner to ensure that your lens is completely clear while you’re in the water. In order to help you make the best choice when researching an anti-fog product, here are some factors you should consider.

Consistency

The consistency of an anti-fog can affect how well it clings onto the lens, which is necessary in order for it to be effective and helpful. You can expect the defogger to come in spray form for easier application.

Typically, the defoggers that have a thicker gel-like consistency clings to the mask for longer and thus can last for an entire day or multiple dives with just one application. However, some people prefer using spray bottles so that they can quickly and easily apply it onto the lens.

Reef-Safe and Non-Toxic

If an anti-fog contains too many strong chemicals, it can emanate harsh fumes that irritate your eyes. You should look for defoggers that are made using non-toxic or natural ingredients so that they won’t hurt your eyes. Avoid products that contain alcohol and read reviews from users to see if they complain about irritation.

Another consideration is if it is biodegradable and safe for the environment. You are probably aware that the ocean is becoming more polluted, and marine life and habitats are getting destroyed by chemicals and toxic ingredients.

The anti-fog that you use on your mask can sometimes wash off into the water, so you should check that it is reef safe and non-toxic. If a product doesn’t harm the environment, you can also rest assured that it won’t be harmful to your eyes either.

2-in-1

Some defoggers double as lens cleaners, and these 2-in-1 products can save you some hassle by simplifying the preparation process. If you really dislike the cleaning process, consider getting a 2-in-1 anti-fog spray.

Price

If the price is an issue, look for products that get you two or more bottles with one purchase. They are the best bang for your buck if your goal is to get the most value. Check the user reviews regarding the application process.

Try to find the answer to these questions. How much product do you need to coat the mask? How long does the product last before you need to apply more? Anti-fog that last the entire day or multiple dives may be better value than ones that must be applied frequently.

If money is really tight, then you can go for the home remedy option. Did you know that your spit is actually an excellent defogger? It’s also good in a pinch, such as when you’re already in the water. Spit in your mask and make sure the spit coats your lens. Rinse out the spit using saltwater and quickly put the mask on. You should have a clear mask that stays relatively fog-free. Pretty good for free, right?

Another option is to mix a solution using baby shampoo and water. Baby shampoo has anti-fog properties and also won’t irritate the eyes. Coat the lens with this solution and then rinse off with either saltwater or freshwater. Quickly put the mask on your face before new moisture makes its way into the mask.

Preparing Your Mask for Diving and Snorkeling

In order for the anti-fog to work with maximum effectiveness, you must first make sure that the mask skirt and lens has been thoroughly cleaned so that there are no lingering oils or debris on the lens.

Before using your mask for the first time, consult the manufacturer’s instructions for pre-use cleaning. Some masks come with lenses that have already been treated using their proprietary anti-fog coating and may not need to be coated with anti-fog before using it.

In fact, being too liberal with cleaning may damage any defog treatment that the mask comes with. If your mask does not come with any defog coating, then before using it you should scrub it with a mild abrasive such as toothpaste and rinse well afterwards.

Even though commercial mask cleaners are effective and relatively cheap, home remedies such as non-gel, non-whitening toothpaste work basically as well. You should use a toothbrush to spread the toothpaste and keep the oils from your fingertips from transferring to the lens. Make sure to cover the entire lens and even the skirt with toothpaste.

To further reduce the chances of oils transferring, you should thoroughly wash your hands to remove any oils including cosmetic oils such as sunscreen lotion. It is important that you take these precautions because the oils will mitigate the effects of the anti-fog.

Some people recommend using fire to burn the mask lens prior to first use. The heat from the flame will incinerate the factory produced silicone layer along the inside of the lens where moisture can get trapped. This step is somewhat controversial, as improper heat treatment can cause the silicone skirt to melt. There is also a low risk of burning yourself.

Keeping the Mask Fog Free

how does a snorkel mask work

The reason that masks fog up is due to a build-up of moisture inside that condenses on the lens. Even though mask fogging is a major issue, there are numerous simple solutions to keep the fogging to a minimum. For instance, defogging solutions are effective as surfactants that cover the lens and minimize condensation.

Be prepared to clean your mask and to reapply a defogging solution each time you head out into the water. Recently, some defogging solutions have become longer lasting, able to last an entire day of snorkeling or diving. These solutions can be found in gel, drops, paste, or spray bottle form.

Application of the anti-fog varies from product to product. Some are rubbed on the lens and left to dry while others are sprayed on. Before diving, you can even buff your lenses clean. There are many options nowadays to defog one’s mask and the methods keep on improving.

With that said, the tried and true methods of using saliva or diluted baby shampoo still work if you don’t have any anti-fog on hand.

Common Ways to Prevent Fogging

If you followed the steps above and still experience fogging, then here are some additional tips you can try out.

  • Double check the seal on your mask. A mask that doesn’t seal properly on your face can lead to fogging (and water leaking). Fogging will occur if there is moisture, and if water is seeping in then it can also rinse off the defog solution that you worked so hard to apply. To strengthen the seal, you can try applying mask sealant or silicone grease along the skirt.
  • Before sealing the mask skirt on your face, make sure no hair is in the way. An easy way to do this is to wet your hair and then slick it to the back. Next, feel around the mask skirt to ensure no stray strands are in the way before forming the seal.
  • Exhaling through your nose increases the moisture in the mask. You will have to do this in order to equalize the pressure, so keep it to a minimum.
  • How careful were you not to touch the mask with your fingers? Remember, the natural oils on your body can prevent the anti-fog from working.
  • Do not expose your mask to sunlight for too long. The increase in temperature can cause condensation to form along the lens. Try to face away from the sun when you are along the surface.
  • After each snorkel or dive trip, thoroughly clean your mask in soapy, warm water to get rid of any lingering oils or residue that may have found its way onto your mask. Let the mask fully dry before storing it away.

Mask Defogging on the Fly

There will be times when you’re out in the water and your mask starts to fog up. Maybe your defogging techniques didn’t work or you made a mistake, whatever the case you now have to deal with a cloudy mask.

You can try washing your mask, also referred to as clearing your mask. To do this, intentionally break the seal on the bottom of your mask and let a small amount of water rush in. Tilt your head down and swish the water side to side until it has rinsed off the fog. Lastly, forcefully exhale with your nose to clear out the water and close the seal to stop water from seeping in.

If you’re by the water’s surface, you can use your saliva as a natural defogger. Spit and thoroughly coat the inside lens with your saliva. Rinse off the saliva using the ocean water and shake as much water droplets as you can. Quickly seal the mask on your face before more moisture gets in.

Best Anti-Fog for Snorkel and Dive Masks Recap

There are many anti-fog products on the market, and in addition to their mask defogging properties you should look for ones that are non-toxic, reef-safe, and long-lasting. You can get anti-fog in gel or spray form. One is not necessarily better than the other, but most people prefer to use a spray bottle to defog their lens.

As part of the defogging process, you must first thoroughly clean your mask because any oils or debris along the mask can render the anti-fog ineffective. Some anti-fog products double as lens cleaners so they can simplify this process.

Even after you’ve treated your mask, you should be aware that you can still cause your mask to fog if additional moisture enters the mask, such as when you exhale or water seeps in. Try not to remove your mask much, if at all, since this breaks the seal and allows moisture from the air to enter which is enough to cause fogging.

Next, it is important to limit how much you exhale with your nose, using it only to equalize the pressure when diving. Low volume masks are better suited for this since it requires less air to equalize. You should also ensure the mask skirt seals tightly against your face.

Lastly, avoid drastic changes in temperature which can result in condensation forming on the lens. This often happens when you surface and allow the sunlight to heat up the air in the mask. Try to face away from the sun or try not to surface for long. If you follow these guidelines, you can find a great anti-fog product and keep your mask free fog-free while snorkeling or diving.
