Hi all,

I have a black silicone omer alien mask, about 2 years old. I use it 2ish times per week for UWR. I have done the toothpaste and/or sea-buff to it roughly every 6 months, and soap-water or before swimming for defogging (glass lens).

I have noticed in the last few months it just doesn't defog as adequately as it did before. Is this expected for masks? do they have a lifespan? Is there something else I should be doing to rejuvenate it?

Thank you!
 

Mr. X

I did the toothpaste thing several times to my.old Omer Alien mask, which has a reputation for fogging up. After a couple of years I used a lighter to burn off the silicone left during manufacture, it finally stopped fogging up so badly. Glycerine/glycerol makes a decent anti-fog alternative to commercial offerings or spit ;)

Periodically washing with dish washing liquid and warm can help keep things clean.

The Omer Alien was ok, the spearo masks I've owned are all very similar. But other masks have been less hassle. The technisub aqualung micromask is my current favourite spearo mask. My wife's Typhoon mask, very similar to the Cressi big eyes mask, is more comfortable and offers a greater field of vision l think.

thanks for the advice guys. I'm so nervous to try the lighter for fear of damaging the mask. I'll give it another good scrub maybe..

how do you recon the mask has a higher propensity to fog up than others, Mr. X?

And I know the technisub mask you're mentioning :) a few of my team mates use it. I'm limited somewhat by my schnozz but am exploring other ones slowly. i love the look of the truly micro masks and especially the mares viper aka batman mask

Hi

From Mr. X
‘...the silicone left during manufacture...’

A silicone spray is sprayed into the mold where the material (grain of molten silicone) will be injected.
It’s to facility the extraction of the moulded skirt that the pulverited spray is used.
It is therefore on the skirt that the residues remain ... and migrate to the glasses ... later.

The lighter does not eliminate what remains on the skirt, which is why the skirt must above all be cleaned internally and externally.

I have had several masks since I started in 1965.
No problem with my traditional way to clean ( dishwashing liquid)…no lighter.
My penultimate mask => https://commons.wikimedia.org/wiki/File:Cressi_minima.JPG

But it was very difficult with this mask to avoid the fog where the glasses touch the skirt. => http://www.omersub.com/en/products/freediving/masks-snorkels/up-m1/

And recently ... "I got very good results by putting it in the dishwasher," 45 ° C glass program "."

On another forum, a diver (doctor of medicine) did not manage to eliminate the fogging by my traditional method… She went to the diving center (Maldives) to have her mask “burned”… It was OK… but later she came back to the forum to say ... sorry, despite the lighter ... the mist returned.

Why ? —> because the lighter don't eliminate the silicone of the skirt.

This one is fog free => https://www.cascoantiguo.com/en/apnea/free-dive-masks/sphera-lx-mask-aqualung

Hi
Nearly everybody says ‘…during manufacturing …silicon residue…on the glass lens’.

They forget to consider silicone mainly is on the skirt.

The guy from 'MAKO spearguns' says at 2:37 from his video : ‘…sun screen products…from your face …migrate to the glass lens over time..

It's exactly what the residue of silicon spray, on the skirt, ( not eliminated by the lighter) will do…migrate from the skirt to the lens over time…like the testimonial I read on a forum…described on my #5

Have they ever seen an injection molding machine and the people who use it?

Don’t use a lighter (*) says…the video specially at 7:23 =>
(*) why taking any risk when soft methods are doing the job…like the dishwasher I experimented successfully recently for my ‘UP-M1’
