3 Household Products That Eliminate Mask Fog

Mask fog is one of the more annoying aspects of diving, especially if you have a bad case that just won’t go away no matter how many times you scrub it with your own saliva at the surface. While you can certainly purchase products rather inexpensively that are designed specifically to tackle this issue, there are actually products right in your own home that can eliminate mask fog just as well or better.

Toothpaste

You read that correctly: toothpaste, the good old fashioned cleanser you use on your teeth every day. The chemicals in the toothpaste lay a protective layer across the lens of the mask thus preventing mask fog from building up inside. Try to use the simplest toothpaste possible because highly abrasive toothpaste can sometimes scratch the lens. Rub the toothpaste across the inside of the lens with a finger or soft cloth until the lens is clear.

 

Lighter or Matches

When a mask leaves the factory, the lens will typically have a layer of residual chemicals from the production process that will ultimately cause fogging. In order to eliminate mask fog with this trick, carefully move the flame of a lighter or match across the inside of the lens until it turns black. Once the lens has cooled, wipe away the soot with a soft cloth. There’s no need to rinse the mask after using this method, but in order to ensure all the factory chemicals have been incinerated, you may need to do it more than once. If soot ceases to form, it is a good indicator that you got it all.

 

Baby Shampoo

The availability of this product in your house may depend on whether any babies are present, but it is easily found at any grocery store. Apply a few drops of baby shampoo and rub it around the entire lens, or use watered down baby shampoo inside a spray bottle, to easily eliminate mask fog. After application, rinse briefly and take care not to touch the inside of the lens to avoid your skin’s natural oils compromising the protective layer you’ve just created. Baby shampoo is more desirable for some divers than regular shampoo or dishwashing soap as it is gentler on the eyes in case there is any remaining residue.

  1. First time I’ve heard anyone suggest the toothpaste is a defogger. The point of toothpaste is to clean the manufacturer residue off the inside glass, THEN spit/defog solution/baby shampoo will fight fog. Done it this way with dozens of masks & recommended it to students, with great results, forevah!

  2. Will this work better than the mask defogger you buy at the stores? I’ve used the store bought stuff and it’s not helping!

  3. I’ve always used toothpaste when the mask comes right out of the box. Before dives I just use spit on the inside and outside lenses. Haven’t had an issue yet.

  4. J&J baby shampoo works great too, last two trips I have used it and NO FOG AT ALL

  5. Spit, rub, rinse before every dive. Always works.

  6. Make sure to get all the toothpaste residue out of the mask. Minty fresh is not easy on eye balls!

  7. Yeah, minty eye balls are uncomfortable.

  8. My Cressi free-drive mask came with instructions to use plain toothpaste as soon as I get it out of the box. Than I spit. I love my spit. I have so much of it. And it’s FREE!!!!!! :)

    If I’m out for 8 hours hovering over the large wall in the Grand Cayman and it gets foggy guess what I do? I rest on the float or tread water and I spit! Don’t need to carry around no baby shampoo like some tourist (which I am)

    P.S. – toothpaste also works great to clean headlights. Ask the Google.

  9. Spit works great.

  10. I keep a small tube of toothpaste with my dive mask and put a tiny bit on each lens, rub, rinse, and go. No fog, and my mask stays minty fresh. lol But it really does work.

    One thing I use his woollight and water 50/50. It cleans the lens and leaves a layer all at the same time.

  13. Glass can crack under a flame and I once saw a woman with soap bubbles inside her mask. She had to surface.

  14. I use a squirt bottle. Put a little baby shampoo in it and fill with hot water to dissolve better. Squirt into the mask, rinse and after working 3 hours underwater no fog.

  15. I wouldn’t want to use flame anywhere near my mask – cracked glass, cracked skirt – it doesn’t bear thinking about. Spit, if you can produce enough to be effective, or baby shampoo if you can’t, both work fine.

    we have been using baby shampoo since our instructor advised this in our open water dive classes 13 years ago. It works great, is cheap, doesn’t sting your eyes and smells good. On occasion we have used commercial products and they are expensive and burn our eyes. Plus, you can also use it to wash your hair if you run out of your normal shampoo on your trip!

  17. Get your mask strapped correctly so you don’t get a leaky dive, snorting thru your nose to flush out the excess water is warm air from within your internals and will tend to fog up your mask. If it fits right then less clearing is needed. The Baby shampoo used by my favorite dive boat is diluted & sprayed on and then rinsed. I try not to use the mask rinse bucket since some use their own spit.

  18. If you don’t need to use a new mask right away…soak the mask in a bucket of fresh water for several days (change the water daily). A 4 day soak is like 100 dives (24 hrs/day x 4 days). That will eliminate the manufacturing residue without taking a flame to or using an abrasive on your new mask.
