Spit or Defog

What do you use when you’re diving and why? Commercial defogs, baby shampoo or spit?

SPIT

Spit is a good option to use because it is effective, you always have it with you and doesn’t cost you anything, only a nice, slimy spit in your mask. Why does spit work? We know that the water droplets hang on the imperfections of the mask, so when you spit on the lenses the lenses become smooth and causes the water (fog) to slide to the bottom of the mask. This is why spit works.

Disadvantages:  Using spit puts bacteria into your mask and overtime there will be mold growing on the skirting of your mask. Your mask will also start to smell bad, looks bad and it is unhealthy.

How to apply: Spit on the inside of the mask and rub it around with your finger. Dunk the mask briefly in the water. Don’t rinse the mask to much, the goal is to leave a thin layer of saliva on the lenses.

BABY SHAMPOO

Baby shampoo works on the same concept as spit. It makes the surface of your mask smooth so that the water can just slide to the bottom of the mask. One benefit of using baby shampoo is cheaper than commercial defog. It also doesn’t put mold into your mask so it is not unhealthy like spit is.

How to apply: Put a few drops of baby shampoo onto your lenses and rub it around with your finger. Rinse the mask briefly in the water, but make sure there is enough baby shampoo on the lenses so that the lenses is smooth.

Baby shampoo containers is weak and not made for travelling. When baby shampoo is in your dive bag and you travel the chances is very good that the container will break or that the lid will pop open and then all your gear will be full of baby shampoo and it will possibly damage your dive equipment.

Baby shampoo will also burn some people’s eyes which will give you a very unpleasant dive.

  COMMERCIAL DEFOGS

If you don’t fancy spitting in your mask you can buy manufactured defogging made by companies such as McNett. Some benefits of using commercial defog is that your mask would not fog up for up to a day. It also doesn’t put bacteria into your mask like spit does. You can put it in your BCD pocket so you can apply it anywhere, and if one of your fellow divers is struggling to defog you can always help them by just opening your BCD pocket. Another benefit is that commercial defogs is made not to damage the skirting of your mask.

How to apply: Follow the instructions that is on the bottle. Most commercial defoggers you either drop or spray the solution on the lenses of your mask, rub it around and rinse it off
