How To Pre-Treat New Dive Mask

A foggy mask can ruin the whole dive experience. If your scuba mask is foggy, you will miss out on the corals and fishes. Additionally, the fog will impede communication between you and your colleagues.

If your free diving mask is covered by fog, observing diving safety will not be possible. It is not uncommon for divers who are distracted by their foggy mask to lose track of their surrounding and buoyancy.

Irrespective of whether you are a professional or a beginning scuba diver, knowing how to pretreat dive mask can help you avoid the fogging issue. This article will make preparing a new dive mask extremely easy for you. If you use the tips in this article, you should see everything in your surroundings during your next shipwreck diving trip.

Why Do New Masks Fog?

Contrary to the expectations of the majority of scuba divers’, dive masks fog even when they are new. This problem arises from the manufacturing process. Generally, a thin silicone layer usually builds-up on the mask lenses.

In the majority of the instances, the layer is not overcome or removed by mask anti-fog solutions. To reduce the chances of fogging when you are under the water, the silicone layer has to be removed manually.

Basically, when you pretreat dive mask, what you will be doing is simply getting rid of the silicone layer. It is worth noting that preparing a new dive mask does not mean that clearing the scuba mask will not be necessary. Scuba mask leaks, which make the mask clearing necessary, do occur on masks which have already been cleared.

How to Pretreat Dive Mask Using Toothpaste

This technique is generally very simple but effective. It makes use of toothpaste to get rid of the manufacturing residue from the lenses.

If you opt to use this method, it is crucial that you avoid using the higher abrasion stain removal or whitening toothpaste. The higher abrasion toothpaste may end up causing tiny scratches on the lenses. This will cause a haze effect which makes the whole process less useful.

If you invested in polycarbonate lenses (plastic lenses) or specially coated lenses, such as color corrective lenses, you should not use this procedure when preparing a new dive mask. This is because the plastic lenses generally scratch pretty easily. Additionally, the abrasion effect of the toothpaste you will use in this procedure could affect the corrective coating

To reduce the chances of your dive mask fogging the next time you wear it together with your dive gloves, follow the steps we have outlined below:

Step 1: Grab your toothpaste and then squeeze a pea-sized amount onto one of your fingers. Make sure that the finger is clean.

Step 2: Rub the toothpaste inside the face of the dry lenses. Use circular motions when rubbing the paste.

Step 3: Again, using your finger, rinse the paste off the mask lenses. Use circular motions.

Note: When used to pretreat dive mask, the paste may end up collecting in the edges and corners of the scuba mask. To get the toothpaste out of the corners, use a soft and wet cloth.

Step 4: After removing all the paste, dry your mask using a soft cloth.

Step 5: Repeat the whole process a number of times.

In the majority of the cases, all the silicone residue will not be removed after you use the toothpaste for the first time. This is the main reason you will have to repeat the steps outlined above for a number of times. To ensure that you won’t have to deal with the fog the next time you wear your diving hood and dive mask, you should repeat the steps for approximately 5 to 7 times.

After you are done with using the toothpaste, take your time to clean the mask thoroughly. This will help you remove all the traces of the toothpaste. If toothpaste remnants are present on the dive mask when you wear it during your next dive holiday, the remnants could affect your eyes.

Preparing A New Dive Mask Using the Flame Trick

To pretreat the dive mask using a flame, you will need a tapered candle or a lighter. If you have gotten either, follow the steps below to get rid of the silicone layer:

Step 1: Run the flame tip over the inside of the dive mask lens. Wait until the lens turns black.

Step 2: Allow the mask to cool and then wipe the soot away with a soft cloth.

Step 3: Repeat this process for a couple of times. Stop when it becomes difficult to turn the lens black.

It is crucial to note that allowing the glass to become too hot is not a good idea. Also, if you invested in a mask that features plastic lenses, do not use the flame to burn the residue off. If you use the flame, you will end up burning the lenses themselves.

You should take precautionary measures to make sure that the flame does not go anywhere close to the silicone skirt available on the mask. A very little heat could end up melting the skirt.

How to Keep Your Mask Fog-Free

If you have already pretreated your dive mask, used a defogger, and you are still dealing with the fog on your mask, there are some things which could help you get rid of this issue. Below, we will show you some of the things you can do to make sure that you can see everything surrounding you in the underwater world when you decide to wear your scuba fins.

1. Do Not Touch the Inside of the Mask

You should try to avoid this, especially immediately after you use the defogger. If you touch the inside of the mask, you will transfer oils into it. This will end up negating the effect of the defogger. Additionally, it will dirty the mask.

While the majority of freediving and scuba diving enthusiasts apply the defogger using their fingers, you should try to avoid this if you find that your mask still fogs after the application. You can invest in a defog that has the ability to swish around inside the mask rather than requiring you to spread it manually. After rinsing the defogger, avoid putting your hands on it.

2. Avoid Breathing Out of the Nose

If you are still trying to overcome your fear of scuba diving, it may take you some time to start breathing in and out solely via the mouth. It is, however, worth noting that exhaling through the nose is one of the leading causes of fogging. When you are under the water, focusing on how you are breathing could help you figure out whether this is the reason you are dealing with the fog.

3. Make Sure That the Mask Fits Properly

Just like you would make sure that the wetsuit or dry suit fits you perfectly before you pay for it, you should ensure that you are paying for a mask that fits you. If your mask does not fit you properly, it will keep leaking. This may force you to breathe out via the nose just to clear it. This may cause fogging.

Additionally, if moisture is getting into the mask, this will promote condensation. This will cause fog to accumulate on the mask.

The ideal mask should not allow any moisture to enter. It should stay dry throughout the scuba diving period.

In most instances, it is next to impossible to locate a dive mask that allows 0% moisture to enter. However, you should focus on locating a mask that allows the lowest amount of moisture to seep through.

Some additional tips you can use to make sure that you do not deal with too much fogging include:

  • Avoid placing your defogged diving mask in the direct sunlight. Also, avoid placing the mask on your forehead.
  • After each successful scuba dive, be sure to rinse the mask with warm and soapy waters. This should remove the sunscreen residue.
  • Before you store the mask in its original case, allow it to dry completely.
  • When you are donning the mask, take your time to feel around its skirt. This will help you confirm that there is no trapped hair under the skirt. Trapped hair could allow water to leak into the diving mask.

Globo Surf Overview

After purchasing a new mask, investing your time into preparing the mask can make your scuba diving safer. Preparing a new dive mask allows you to remove the silicone layer which contributes to fogging, in the majority of the cases.

If you are trying to determine whether to pretreat new dive mask using the toothpaste or fire, the toothpaste method is much better. When you are using fire to pretreat dive mask, things can go wrong even when you think you are being careful. The only precaution you need to take when pretreating the mask with toothpaste is to avoid using high abrasion pastes.
