Small Amount Of Baby Shampoo Or Dish Soap Mixed With Water
Defogging a snorkel mask with a small amount of baby shampoo or dish soap mixed with water is a popular home remedy for preventing foggy lenses. However, it is essential to note that not all types of soap are suitable for diving masks, and using the wrong type of soap can damage the mask or make it less effective.
The following steps will help you defog a snorkel mask using baby shampoo or dish soap mixed with water:
- Clean the mask thoroughly with fresh water to remove any dirt or debris.
- Mix a small amount of baby shampoo or dish soap with water to create a solution. The proportion of soap to water should be small, such as a drop or two of soap to a cup of water.

Note:
Using baby shampoo or dish soap can be more effective at preventing fogging than defogging an already foggy lens. Also, it is only a guaranteed solution for some masks or in some conditions.
You should avoid using these solutions if you have any allergic reactions or other discomforts. Instead, seek proper defog solutions specifically designed for diving masks.

Rub Toothpaste Or Shaving Cream On The Lens And Rinse It Off
Applying toothpaste or shaving cream to a snorkel mask lens and then rinsing it off is a method that some people use to defog their mask. The idea is that the toothpaste or shaving cream creates a barrier on the lens that prevents water droplets from condensing and fogging up the mask.
To use this method, you will need to apply a small amount of toothpaste or shaving cream to the inside of the mask lens. Then, spread the paste evenly over the lens using your finger or a soft cloth. Once the lens is coated, rinse the paste thoroughly with fresh water. Then, shake off excess water from the mask and let it dry before using it. Be sure to avoid getting any paste on the mask’s skirt, as this can make it uncomfortable to wear.
Note:
We recommend you use anti-fog solutions formulated for scuba or snorkeling masks for an impacting result. The toothpaste method may only work for some snorkelers or must be repeated a few times before use. You need to clean the lenses after use. Do not let the paste stay on the lens for long periods.
Mixture Of Water And Antifog Solution (Shampoo Or Liquid Soap Drop)
Using water and an antifog solution will prevent snorkel masks from fogging. You can achieve this by adding a small drop of liquid soap or shampoo to the inside of the mask lens before diving. This method involves the following steps:
- Fill a small cup with fresh water.
- Add one drop of liquid soap or shampoo to the cup of water. Mix it well.
- Using your finger or a soft cloth, apply the mixture to the inside of the mask lens, spreading it evenly over it. Be sure to avoid getting any mixture on the mask’s skirt, as this can make it uncomfortable to wear.
- Rinse the mask thoroughly with fresh water to remove any excess solution.
- Shake off excess water from the mask and let it dry before using it.
Keep Your Hair Away From The Mask
To prevent a snorkel mask from fogging up, keep your hair away. Hair can trap moisture from your breath and cause the mask to fog up, so keeping it out of the way is essential. A few ways to keep your hair away from the mask are:
- Tie your hair back in a ponytail or bun. It will keep your hair off your face and away from the mask, reducing the chance of it fogging up.
- Use a swim cap. Wearing a swim cap will keep your hair tucked away and out of the mask, which can help prevent fogging.
- Use a mask with a low-volume design. Some masks have a low-volume design, which means they sit close to your face. It can help keep your hair away from the mask and reduce the chance of it fogging.
