Does spitting inside your mask can keep it from fogging up?
When a mask has been spit in, water can only form large, spread-out droplets because of the reduced surface tension. The large droplets are comparable in size to raindrops and do not stick to the mask in a fog. Instead, they roll to the bottom of the mask, leaving the glass clear.
Why do you spit into goggles?
Well the explanation is pretty simple; your face inside the goggles is warmer than the outside of the goggles facing the water, creating condensation. This in turn creates fog – steaming up your goggles. If you don’t mind a bit of spit, saliva is the free and easy fog free solution.
Is spit good anti fog?

How do scuba divers keep their masks from fogging up?
Many divers carry a bottle of watered-down baby shampoo with their dive gear. A few drops rubbed into the lens and then briefly rinsed out keeps a mask from fogging. Baby shampoo is preferable to standard shampoo, as it is generally hypo-allergenic, less irritating to your eyes, and biodegradable.
How long do you have to wait between dives?
Surface Interval Time (SIT) must be at least 10 minutes between dives. If your SIT is less than 10 minutes, you must consider your second dive as a continuation of the first dive. NAUI recommends a SIT of at least one hour between dives.
How do I defog my scuba mask?
Simply dab or squirt the baby shampoo on the inside lens of a DRY mask and rub evenly with clean fingers (no sunscreen residue– sunscreen will remove the surfactant). Rinse briefly in either fresh or salt water. NOTE: DO NOT rub the lens or touch the lens during or after rinsing.
Why do masks fog?
The lenses on your mask are in contact with the water outside, which compared to the air inside, is quite cool, even in the tropics. The water vapor molecules are constantly bouncing around in your mask, so when they hit the cool mask lens, they in turn cool down and turn back into liquid.
How do you spit in a diving mask?
Instead of bringing toothpaste on each dive you can also use spit. For an easy clean: just before you go diving, spit in the mask, rub it around and rinse it with water. This you need to do right before you put on the mask as well, otherwise it won’t work.
Why can I Gleek?
Ordinarily the ducts just sit there passively like water pipes while the glands ooze out saliva to keep our mouths juicy. Squeezing them forces the saliva out in a spray; we can’t gleek again until they refill. So to answer your “what’s the purpose?” question, there’s no purpose.
How do you keep your glasses from fogging up with a mask?

Does Toothpaste stop goggles fogging?
Toothpaste Recommended by scuba divers, another popular method to defog your goggles is to use toothpaste! Like the baby shampoo, a coat of toothpaste can prevent condensation from forming on the lens of your goggles.
Why do you spit on your mask when you swim?
FreeDiver.net explains, “Spit keeps the air on the inside of the mask from condensing on the glass.” Masks fog up because the inside is often dirty or dusty. Spit cleans off the dirt, making it much harder for condensation and fog to form.
Why is there water inside my scuba mask?
It is because of the balance of temperature and dew point. When the temperature of the air inside of the lens is below the dew point, then water will condense on the inside of your scuba mask. Your eyes cannot see them, but the inside of your mask surface is covered in microscopic indentations.
Why do masks fog up?
Masks fog up because the inside is often dirty or dusty. Spit cleans off the dirt, making it much harder for condensation and fog to form. It may not be sanitary, but for most divers it works just fine.
What can I use instead of spit for scuba diving?
Spit being a natural bodily fluid also doesn’t irritate the divers eyes unlike a detergent or soapy liquid which could sting. You could just as easily use shampoo, detergents, toothpastes, soaps, alcohols, or glycerin all used by divers as a spit alternative used to the same effect. You could also purchase manufactured defogging solutions.
