A foggy diving mask is extremely annoying. It really is a pleasure to kill the underwater view spoiled by mist. Who wants to be constantly flooding and clearing a mask when they should be enjoying what’s in front of them. But don’t worry, there are useful and easy solutions to this problem.

Spitting is not the only solution
Very often, you hear the call “JUST SPIT”. Yes, it is a quick and cheap method. I’ve been told that smoker’s drop works best, but I’ve never used it as an excuse to smoke.

But there must be more effective and lasting solutions against fog.

Mask Fog Prevention Checklist:
In addition to defogging, there are other things you can do to help prevent your goggle from fogging up:

1) When you buy a new mask, clean it thoroughly with soap and water and clean both the inside and outside of the lens with toothpaste. This will help remove any residue left over from the manufacturing process.

2) Don’t use too much sunscreen or moisturizer on your face.

3) Rinse the mask with fresh water before each dive.

4) Be careful not to scratch or damage your mask during storage or transportation. When not in use, it should be dried and stored in a case or hung from its strap.

5) Breathing through the nose contributes to fogging. Try to relax and breathe through your mouth.

The 5 best face mask defoggers
There are all kinds of expensive concoctions that promise the land. People say they work, but I’ve stuck to the cheaper options; many of them are easy to find in most kitchen cabinets or on supermarket shelves.
Here is a list of my top 5.

1. Dishwashing liquid
Eliminates the accumulation of fat that favors fogging. Just rub some into your mask with your fingers and rinse well. For its price and availability, you get the best billing.

2. Cat shit
This waxy defogger with an unattractive name is quite useful and inexpensive. It is a slightly more durable solution than soaps and detergents. Apply Cat Crap before a big dive trip or weekend and it should help reduce fogging considerably.

3. Gentle scrub
This is a household cleaning product found in most retailers. It is a bit abrasive but not as gritty as Comet, Ajax and other shower powders which are probably too abrasive for the purpose and can scratch the mask.

4.Shaving cream
Rub a little inside your mask, rub and rinse. I have no idea why it works but it seems to keep the mask clear for a dive.

5. potato
I have tried it and although it does not seem spectacular to me, there are those who use this method. Just dab some potato juice on the mask lens and rinse well. But don’t try to take a potato abroad. This could cause problems for the authorities that enforce food import laws.

A combination of methods usually works best. At the beginning of the dive trip, clean your mask with something slightly abrasive like Soft Scrub and before each dive, clean with dishwashing liquid. Beyond that, there is, of course, some good spit.
