Method 1: Cleaning A Snorkel Mask With Toothpaste

Dirt is one of the major reasons behind the fogging up of your snorkel masks, as water loves the cozy environment due to dirt and sticks to the glass.

Hence, cleaning a snorkel mask with toothpaste can help you with the fogging. Here is the step-by-step guide:

  1. Start with putting just a little bit of toothpaste both on the inside and outside the lenses (use a couple of dabs, not more than that).
  2. Now take a microfiber cloth and gently scrub the inside and the outside of the lenses. If you do not have a microfiber cloth, use a soft towel and do not scrub too hard.
  3. Make sure your fingers do not touch the glass, as they have a certain amount of natural moisture in them. Do not use a brush for scrubbing as well. It can cause scratches that can worsen the fogging.
  4. Once the mask is lightly scrubbed, rinse the lens with warm water to remove the toothpaste thoroughly.
  5. Now take a microfiber cloth, use the unused part of the earlier one and clean the lenses dry.
  6. If your mask is dirty, it might take more than one round to make the lenses spotless.

Toothpaste is one of the magic cleaners, they can also be used in cleaning cymbals, and also has a few soothing properties in case of acne. Moreover, it is gentle and hardly has any side effects because of its mild properties.

Method 2: Applying an Anti-Fog Spray to the Inside 

If you want to win this fogging war, this step is necessary to follow. Once the cleaning is done, you need to move forward with applying an anti-fog spray to the inside of the snorkel mask.

Here are the step by step instructions:

  1. The most pocket-friendly way of going around this step is to mix a little bit of baby shampoo with clean water. Make sure to mix five parts of baby soap and one tablespoon of water.
  2. Apply this mixture to the inside of the snorkel mask.
  3. The best method to put an even coat of the mixture is by using a spray bottle. So, put the mixture into the spray bottle and spray an even coating of the mixture on the lenses.
  4. If you do not have a spray bottle, go with putting a little bit of solution directly on the mask and move it around to spread it equally on each side.
  5. Once the spreading is done, clean the lenses dry with a soft and clean microfiber cloth for the best results.
  6. Do not use the anti-fog solution outside the lens, as the fog is not accumulated on the outside, and avoid touching the lenses with fingers due to natural oils.

After using this method for cleaning your snorkel mask, you are all set up to make as many dives as you want. Here is the link to a video guide for cleaning the snorkel mask when you run out of anti-fog spray.

Method 3: Do Not Forget to Rinse Your Mask After Every Snorkel

The best advice you can get regarding cleaning and maintaining a snorkel mask in the ocean or beaches is not to forget to rinse your mask after every snorkel.

This advice goes for everything you wear, like swimsuits, action cameras, wet suits, etc.

  • Do not forget to use fresh water to rinse off all the extra dirt particles from your snorkel after each dive.
  • If you avoid regular rinsing, the dirt and the salt from the ocean and beaches will degrade the plastic and silicone parts of the mask, thus resulting in the premature aging of the material.
  • If the advice is avoided, your mask seals and adjustable straps will be compromised, thus do not forget to give a good rinse after each dive. 
  • This advice is also valid for full-face snorkel masks.
  • After every dive, make sure you focus on the lenses, adjustable straps, the frame, and the silicone skirts of the mask.

  • Try to go for a home-based DIY to save you some money because even if the spray works, it might not be that good at the ocean.
