Is your mask fogging up on you?
It's very common for new masks to fog up when using for the first couple times. Why does this happen? Well, it's because the temperature of the lens drops below the dew point of the air inside the mask causing condensation. The water droplets adhere to the residue left over from the manufacturing process that coats the lens, dirt and oils on the lens from normal use and simple microscopic imperfections on the lens. That's great, but all you care about is how to prevent this, right?
According to krankenaquatics.com, you need to pretreat the lens of your mask and here's how....
- Take a thimble-sized amount of common white non-gritty, non-minty toothpaste and rub it on both sides of the lens while the lens is dry. Avoid gel toothpastes.
- With clean fingers, give it a good circular rubbing motion and cover the entire lens on both sides.
- Rinse the lens with clean water to wash away the toothpaste. Use more water pressure or a wet washcloth to clean difficult areas.
- Completely dry the lens with a clean towel or rag.
- Repeat the steps above a few times drying the lens each time.
Once this is accomplished there are a few defogging solutions that should be used before each use.
- Commercial defogger (can be purchased from any dive store)
- Baby shampoo
- Your own spit
Apply anyone of these options, before you enter the water, to the inside lens of your mask. Give a light rinse and don't touch the lens after. The idea is to keep a small amount of the defogger on the lens.
This will improve your diving experience. I hope this was helpful! And now get out there and have fun!
