How to Pre-Treat a Dive Mask - video

Have you ever seen a mask fog-up underwater? Or wondered why your brand-new mask fogs up immediately?

The majority of mask lenses have a very thin layer of silicone that is applied to the lenses during the manufacturing process to help protect them from abrasion damage and scratches whilst they are being built and transported. The problem with this thin layer is that when not removed properly before you start using the mask the lenses will almost certainly fog very quickly.

It is important to note that masks with special anti-fog, UV or other coatings can be damaged by this process, so please only use it on normal lenses. If you are unsure please contact us, and we'll be happy to assist you.

Fortunately there is a very quick and easy way to stop this from happening, just follow the simple steps below;

  1. Get your mask and either a mask pre-cleaner like McNett Sea Buff or some ordinary abrasive toothpaste (Not Gel!)
  2. Place a small amount of Sea Buff or a blob of toothpaste on the inside and outside of the lenses
  3. Rub the paste around on the glass, you can do it quite hard as it won't scratch the glass!
  4. Thoroughly rinse the paste off (no need to leave it to dry, it is not a chemical reaction but an abrasive action!)
  5. Dry off the lenses and buff
  6. Repeat this process as necessary, normally a couple of times is sufficient!
  7. To finish and after each use apply an anti-fog solution such as the McNett Sea Drops to maintain a protective layer over the lenses to help prevent condensation forming on the glass.

These short videos will show you how to properly prepare your mask to hep prevent fogging. It should be noted that these methods are only recommended for lenses that haven;t been pre-treated with a manufacturer anti-fog, anti-reflective or UV coating as it could damage the coating.
