Ok, I don't get why nobody really talks about this, but a really big factor in fogging your mask is the temperature difference between your skin (the heat that your skin on your face emits) and the face mask glass temperature (=temperature of the water). A good way to reduce this issue is to cool your face directly in the water for 10-20 seconds right before you put the mask on.

Spitting continues to work fantastically, for many years 😊

As a retired commercial saturation diver in the North Sea for 15 years, I can tell you the only way to keep a helmet lens (or a mask) from fogging up for over 8 hours each day is "shampoo". Preferably the thickest stuff you can find. I used to use 'Prell". No idea if it's still made or the same thick stuff it used to be but it was the absolute best stuff you could use. Clean and dry the lens, apply a 100% layer of the shampoo, wipe of the excess ensuring a complete thin even film of the shampoo. No excessive blobs of the stuff. Shit lasts an entire 8-10 hours. Now Ive retired I only free dive to shoot fish and some old fashioned spit works for that sort of diving but if I'm going scuba diving on vacation I'll still go for some dish soap!

Great video. Something else I think is important, is to make the glass dry before adding the defog. Many people dip the mask in water prior to adding the defog solution, and it prevents the defog from being most effective. No need to clean or rinse the mask prior to defogging, as the process of scrubbing and rinsing the defog will take care of that (cleaning) as well.

[lynnmanganella]

black tea works wonders! We always put a sip in our mask before the dive and let it sit for a few minutes. Asante Sana to our Swahili friends who taught us that method

[zainalarsyiq]

Hello guys.. I am a PADI Divemaster.. Whenever I got a new mask, I will burn my mask using a lighter but I would suggest that you use a blue flame lighter because it is easier to control like a small lightsaber and you won't get the black residue from the normal orange fire.. I usually kept a blue flame lighter with me all the time as i'd help anyone that wants to burn their mask because i dont want them to ruin their equipment.. Antifog prep before each dive is a must even after you burnt your mask.. All of it works i.e toothpaste, saliva(phlegm is the best 😅), antifog, baby shampoo(would recommend johnson n johnson) they all work..

[graceoverall]

Baby Shampoo all the way. 2 parts water to 1 part shampoo in a little travel size finger pump spray bottle, like a glasses cleaner spray bottle if you have a spare one of those. I find it a good habit to apply every time because then you have that confidence that you haven't forgotten to apply often enough. Works excellent for goggles in a pool as well.

[miquelom]

I only do freediving, and with the goggles dry, I dip my finger in saliva and lightly rub the glass. Then I rinse it with sea water and that's it. It usually works almost always well.

[emotravelph]

The two methods to prep a new dive mask was well explained in this video presentation. In addition after all that done, before every dive, I apply a drop of dishwashing liquid on the lenses. I place the dishwashing liquid in an eye drop bottle and bring it with me in my dive bag. Works great and I just reapply on each dive.

Thank you for so much great information.
My husband & I are new divers (20 dives) and we keep coming back to your channel/videos for well made educational videos.

[ALFarrell-kvok]

I swear by a few drops of Johnson's baby shampoo (50% water+ 50% the shampoo) rubbed on both sides of glass and then thoroughly rinsed off the glass and skirt.

[ALFarrell-kvok]

While we're talking about masks, have any of you tried putting silicone grease around the inner side of the mask skirt where it touches the skin prior to a dive. I find it gives such a good seal against any water sneaking in.

[MarcoChristensen]

Spit and rinse once works fine. Done it for 35 years without any eye problems. Shampoo would be larger risk of getting eye infection if you dont rinse properly. :)

[JJVPYOU]

I used to use Spit, and no, not the one that comes in a bottle, but the one that comes out of my mouth. Cheap and readily available.

[souswes]

“Spit” is a great commercial defog. I always keep baby shampoo though. More recently on the film removal I’ve run my mask through my dishwasher on the top rack and it seems to have been effective! Great vids as always.

[Pscribbled]

I’m a freediver so take it as you want. But I burn my new masks then spit, rub and rince (in sea water) my mask before each dive. Works everytime and I never get foggy

[deeplou]

I use baby shampoo & water ( exact proportion varies) not too rich in small spray bottle. I spray the lens and leave it. I don't put it in rinse bucket ( who knows what eye infection lurks in that water) . After getting in the water, a little flood, swish it around, blow it out. Works great, and I don't get someone's pink-eye

[olegvassiliev]

thanks for the tip. sea buff worked like magic, it takes 5 minutes and fog has gone completely.

[divingwithjuliouz]

Been snorkeling and diving practically my whole life
I’ve ran through so many masks and Both Methods work great, I’d prefer to burn my mask carefully (once) then from there I’d just apply dish soap but the best is Baby shampoo and a lil water
Super clear mask! 😎

[robertblair]

I always put shaving cream on the lens. I polish it off with a clean cloth. It works for me.
