Scuba Diving Mask Fogging, How to Prevent It.

#scubadiving #equipment #mask #fogging

One of the most annoying things that can happen while scuba diving probably is a fogging mask! A fogging mask will most likely make your scuba diving experience less enjoyable since you will not be able to clearly see the beautiful fish and corals of the dive sites you are exploring, as you will keep trying to clear up your mask ( a basic skill that you can learn during your PADI Open Water Diver Course in Bali). So let us give you a few tips and tricks on how to prevent your mask from fogging so to fully enjoy each of your dives.

New Scuba Diving Mask

Have you recently bought a brand new scuba diving mask? Great idea! What you need to know tho, is that new scuba diving masks have leftover residues from the manufacturing process from the factory. If not treated properly before diving, this residual coating on your mask's lenses can lead up to fogging. Here are two methods that will totally help to clean your mask:

The Toothpaste Method

Just rub some toothpaste on the inside of your mask's lens, to rub the toothpaste you can use your fingers, a piece of cloth or an old tooth brush, after some good scrubbing rinse it off with fresh water. Be careful not to use an abrasive toothpaste as it can scratch your lens, the simpler toothpaste the better, This process needs to be repeated a few times for best results. What can also help is to leave the toothpaste spread over the lens for a few hours so to give some times to chemicals to react.

The Lighter Method

This is probably the most effective way to treat your new diving mask. Simply run the tip of a flame, from a lighter or a candle, on the inside of your mask's lens until the glass turns black, this is the sign you are actually burning all the factory residues.Once the glass is totally black, wait for it to cool down and wipe it clean with some cloth or tissue. Repeat the process until the glass does't turn black anymore. It is very important that you don't let the glass become too hot, and you also need to be very careful to avoid to let the flame touch the silicone of your mask as this can melt quickly. Junior divers, don't do this alone ask an adult or your diving instructor for help!

Used Scuba Diving Mask

Used scuba diving masks should be treated for fogging before each dive. To do so you will have to use a defogging agent, which is a substance that will prevent condensation to deposit on your mask's lenses. Let's have a look at the most popular defogging agents:


All you need to do is spit on the inside of your mask and rub it on your lens, after that, rinse your mask making sure to leave a layer of saliva, remember to do this right before the dive as saliva can easily dry out. Spitting is free, echo-friendly and acceptable when you do it in your mask before diving, however some people might find it gross specially when using rental gear.

Commercial Defoggers

These products are specifically designed as masks defogging agents, any dive gear shop or website will have one or more for sale. All you need to do is pour some defogger on the inside of your lens, rub it up and rinse it with some water, remembering to leave a layer of agent on the lens.

Baby Shampoo

Baby shampoo works exactly like commercial defoggers and needs to be used the same way: few drops on the inside of your lens, rub it up and rinse it remembering to leave a layer of baby shampoo on the lens.. Baby shampoo is quite convenient as it is very easy to find, quite cheap, not eye-irritating, biodegradable and last but not least it smells good!

Hope this few tips and trick will help you dealing with your fogging mask.
