Disappointed in the way this worked and even used magic drops but still have the fogging issue
Hey Lara! When using those two products together you'll need to make sure the lenses are completely free of Magic Drops before applying the FogBlock. Since the Magic Drops are a lens cleaner, they can actually remove the anti-fog coating that is applied by using the FogBlock. Check out our FAQ section for more tips and if you just can't get it to work out let us know and we'll do our best to make it right!
The pros are that it definitely cleaned my goggles well and before I got in the water they were super clear. As I swam for an hour they ended up fogging up a bit but defiantly less than normal. I will continue to use it and think that overall it cleaned my goggles very throughly and will continue to reduce the amount of fog.
Love this product. It works.
A friend recommended Nerdwax FogBlock cloths during covid as there were the only product that kept her glasses fog-free for long periods of time while wearing a mask. We tried then and they work great. BUT… BONUS, we sail a lot they work great for keeping sunglasses fog-free while we are sweating in warm climates AND in very cold climates where we are getting fogged up from steam escaping from our many layers. AND, AND, I started using them on our snorkeling gear - bam! Better than any of the many anti-fogs I’ve tried. Bought two three packs as our snorkeling friends raved about how fog free their goggles stayed after I gave them a Nerdwax treatment. Thank you for making an awesome product that really does the job well!
