Best Ways To Keep A Mask From Fogging

When diving, a foggy mask can ruin the underwater experience. Fog can block the view of the diver and delay communication. In some instances, a foggy mask can become hazardous. When distracted by fog, a diver can lose composure and awareness. However, there are several ways to prevent masks from fogging. Whether using used or new masks, it is important to remember that each should be treated differently. Key West diving will generally require a scuba mask. In order to enjoy this beautiful experience, it is essential to prevent fog from collecting on the mask.

New Diving Masks

New scuba masks typically collect residue on the lens during the manufacturing process. The lens will continue to accumulate fog regardless of applying defogging agents. The coating on newer masks must be removed from the inside of the lens in order to prevent fogging. There are two easy methods of removing the residue.

Use a Flame

Running the tip of a flame across the inside of a lens can burn off the residue. This process will turn the lens completely black. Wiping away the soot using a soft cloth will cause the excess residue to come off as well. In most cases, a lighter or candle is sufficient. This process should be repeated until it is difficult to get the lens to turn black. Using a flame will remove any residue from the lens and can help prevent fogging.

Apply Toothpaste

Placing toothpaste on the inside of the lens and rubbing it around generously will help coat the lens. It is important to avoid using toothpaste with bleaching agents. Scrubbing the mask multiple times and leaving the toothpaste on overnight may help the chemicals react quickly. Avoid using a rough cloth or abrasive toothpaste. These items may scratch the inside of the lens.

Used Diving Masks

A used diving mask should be treated with a defogging agent prior to each dive. If a defogging agent does not prevent fogging, more than likely residue may still remain on the mask from the manufacturing process. Commercial defogging agents are a popular method for preventing fog. These agents are designed to coat the lens and prevent fog. Some divers suggest using a potato to wipe the inside of the lens to reduce fogging. However, there are several other methods that can be just as effective.

Use Saliva

Spit is the easiest and most cost effective method of preventing fog. Although this method may seem ineffective, it works well. Rub a small amount of spit on the inside of the mask then dip the mask quickly in fresh water. The objective is to apply a thin layer of saliva on the inside of the lens. It is important to remember that this process does not work well if the mask dries prior to diving. Therefore, this technique should be completed immediately before a dive.

Baby Shampoo

Baby shampoo is used like most defogging agents. Rub a couple of drops of baby shampoo on the inside of the lens and rinse the mask. This will help prevent the mask from fogging up. Baby shampoo it hypo-allergenic and is preferred over most standard shampoos. This is primarily because it is less irritating to eyes. More importantly, it smells better and is biodegradable.

Glycerin Soaps

Detergents and glycerin soaps are used like most defogging agents. Place a couple of drops on the inside of the lens and rub it around generously. After rinsing the mask, the lens should be evenly coated. The problem with this method is the soap can begin to burn the eyes. For that reason, rinsing the mask is extremely important. This method is effective for preventing fog, although it may have a considerable drawback.

Key West diving can be an incredible experience. Whether using toothpaste or defogging agents, it is important to prevent the mask from accumulating fog. Viewing the beautiful underwater scenery in Key West is an experience like none other.
