What can I use to keep my dive mask from fogging up?

Spit just doesn’t do it for me…Anyother suggestions or products?

True, you can use spit but it really doesn’t seem to be as effective as defog that is sold in dive shops and some sporting goods stores. Baby shampoo works well too. My favorite is liquid dish soap! I know, it doesn’t sound like a good idea but hear me out.

Wet your goggles and place one drop for goggles. Masks may need more. Spread the liquid evenly. RINSE WELL (I give my mask a few shakes in the water) to avoid stinging later on. Do not use your fingers to rinse because you will remove the film. Your fingers have oils that will cause your goggles to fog too.

The reason I like dish soap because it is cheap and readily available. Most are biodegradable.

Why it works…after washing, dish soap leaves a ‘sheeting film’ that prevents dishes from leaving water spots on dishes. It is gone after it evaporates. When you wear a mask or in this case goggles it traps moisture inside so it doesn’t evaporate.

You may have to reapply if you remove your goggles for too long or often. Remember to rinse it well. I have used this for hundreds of diving customers with no allergic reaction but if you do get irritation, discontinue.
