Scuba Clear Defog

Even after treating a new mask to a toothpaste clean or using a lighter to get rid of the silicone left on the lenses by manufacturers, masks still have a tendency to fog up on first dives. I use this de-fogger before every dive and it never lets me down. I tend to spit on my mask first, wash it and then apply the de-fogger for one minute. All my dive buddies ask to use it too.

Had some trouble with mask fogging up. This helped a lot. Has to be reapplied though, but lasts approximately a dive or two.

Your mask or camera housing getting fog..? With this spray you will not have the problem again. It usually last a few dives

Does what it is designed to do, use a small amount and rub in then rinse, simple and effective but not as cheap as using spit

I have been using this product for some time even a week in the red Sea in the warm waters works every time tiny little drop on both the inside and the outside I find works a treat
