Mask in the freezer??

[scubapigforever]

Got a new mask this morning and the guy in the shop told me that to stop it misting up on its first few dives to leave it the freezer (after washing it out). Having been diving for over 15 years, I have tried just about every other trick in the book for stopping new masks misting up but had never heard of using the deep freezer. According to the guy in the shop, the freezing changes the mollecules in the silicone - the theory being that it is the reaction of the silicone changing temperature that causes the misting up. Does anyone know if this is bull****? I have a distinct feeling he was winding me up...

They do this pitch with firearms, too. Cryo treating the barrels.

What does fogging have to do with silicone? After the initial removal of processing oils and lubricants, not much.

Toothpaste. Once before every dive. Dive shops just don't know where to buy it cheap enough to make a 500% return. Don't get me wrong, I love the LDS concept, but if people want it, they should (?) sell whatever people want... maybe.

So, how much was he going to charge you to use the freezer? They're going to need one on every dive boat

Toothpaste. Did I mention that?

Hmmmm.... I only toothpaste my maskes one time and dont have a problem with fogging. I use good old spit before evey dive or every time I brake the seal above water.

Does the gel work? What flavor?

No no dont use the gel use the basic cheapest paste nice and gritty. and as to the flaver of my spit depends what I eat before I go diving:blinking:

Silicone is so thermally stable that I can't imagine anthing happening in a domestic freezer.

Yeah, I don't see silicone coming off in the freezer. However, take a lighter to it and it certainly will come off. I use a lighter in the inside of my mask (don't burn the skirt!) and follow it up with a non-gel toothpaste. The combo of first loosening/burning the silicone with the lighter and then the abrasive action of the toothpaste has resulted in perfect masks-no fogging with the last four I've done it with (okay, so I was searching for the right mask-which I found, a SP frameless).

How much does it cost for someone to spit in my mask:huh:
