Defog your scuba dive mask or snorkeling mask to add enjoyment to your underwater adventure.
- Safe for all glass and plastic lenses and will not harm surrounding silicone or rubber support frames
- Powerful and long-lasting while not being abrasive or leaving color residue
- Non-toxic, biodegradable, alcohol-free
- Not recommended for swim goggles
There seems to be a "sweet spot" where if you use too little, the mask still fogs up, but too much (and not rinsed well enough) and there can be gobs of the stuff obscuring your vision. I would recommend using this, though!
