A scuba mask that fogs over underwater is a nightmare to scuba divers. It will either cut your scuba diving adventure short or it will lead you to lose your focus, causing more problems. There are, however, several ways to prevent this from happening. Here are a few things that you can do to stop your scuba masks from going foggy.


Here are some recommended options to prevent fogging in your scuba mask:

  1. There are actually commercial defogging agents available on the market that are specifically designed to coat the lens of your mask. You only need to place a few drops of the liquid onto the lens and rub it around using your finger. Rinse it afterwards with fresh water. Always remember to leave a thin layer of the defogging agent inside the mask and not rubbing out the substance while you are rinsing it.
  2. Another option is using baby shampoo. It is affordable and it can be used the same way as the defogging agent. What divers usually do is that they bring along diluted baby shampoo with their scuba diving gear. It only takes a few drops, a small rub, and a brief rinse to keep the scuba mask from fogging. Baby shampoo is also preferable due to its hypo-allergenic contents compared to other commercial shampoos. Not only is it biodegradable, it will also make your scuba mask smell good too.
  3. You can also use toothpaste if you don’t have the aforementioned things. You just need to make sure that the toothpaste that you are using is non-abrasive. Apply it to the inside of the mask and rinse it gently using fresh water. If you are highly sensitive to minty fragrances, make sure to thoroughly rinse the mask before you wear it.
  4. Using dishwashing agents and glycerin soaps is also one affordable way to prevent fogging. These work almost the same as baby shampoo. It is as easy as applying a few drops on the inside of the mask’s lens and cleansing it with clean water. The only disadvantage in using or applying too much of these is that they have the tendency to give your eyes a stinging sensation. Thorough cleansing with water is a must until it no longer stings when worn again.

These are just some of the high-recommended options to prevent fogging in your scuba mask. Seek advice from your local dive store for further assistance.
