How to Stop Your Mask Fogging

A fogging dive mask can be very annoying, this can turn a great dive into an average one. There are several methods you can use to prevent your dive mask from fogging up before you use it for the first time or before any dive.

Preparation Before Diving:

Toothpaste: Before your dive, apply a small amount of non-abrasive toothpaste (without any added whiteners or gels) to the inside of your mask lenses. Rub it gently with your fingers and then rinse it thoroughly. This leaves a thin film that can help reduce fogging. Definitely on a new mask do this a couple of times before your first use.

Anti-Fog Solutions:

Sea Drops or Sea Gold: At Dive HQ we sell commercial anti-fog solutions specifically designed for dive masks. These solutions create a thin film on the lens that prevents fogging and are applied before each dive. We use either Sea Drops or Sea Gold.

Baby Shampoo: Some divers use a diluted mixture of baby shampoo and water. Apply a few drops to the inside of the mask, spread it around, and rinse it off. The soapy film can help reduce fog.

Spit Method:

This is a common and cost-effective method. Spit on the inside of the mask, rub it around the lens, and rinse it out. Your saliva contains enzymes that can help reduce fogging. Be sure to rinse thoroughly before putting on the mask. When in humid conditions the commercial solutions work best

Proper Mask Fit:

Make sure your mask fits well and creates a good seal around your face. A proper seal helps reduce the exchange of warm, moist air from your face with the cooler water in the mask, which can cause fogging.

Avoid Exhaling Through Your Nose:

Make sure you breathe in and out of your mouth, rather than out your nose when using the mask. Exhaling through your nose can introduce warm, moist air into the mask, causing fog.

Ventilation and Defogging During the Dive:

During the dive, if you notice fogging, lift the lower edge of your mask slightly and allow a small amount of water to enter. Swish it around to rinse away the fog, then exhale gently through your nose to clear any remaining moisture.

Experiment with these methods to find the one that works best for you, as effectiveness can vary depending on factors like water temperature, humidity, and personal preferences. Keep in mind that some masks come with anti-fog coatings, but these coatings may wear off over time and with regular cleaning.
