Reef Safe Anti-Fog Spray for Swim Goggles, Snorkel, Scuba & Ski Masks – Defogger for Diving, Snorkeling – 2Fl Oz

We have our own snorkel equipment and have it used for the last few years (we each have very different types of masks). I purchased this for our most recent snorkelcation in early April 2026. For my mask, the spray provided crisp visibility with zero fogging each day I had used it (3 days). On the fourth day, I did not use it and my mask had a little bit of fogging as a result, although fogging has never been a significant issue with my mask. For my husband's mask, the situation was different. The first day his mask had zero fogging, but he experienced significant fogging on the remaining 3 days. To be fair, I think his issue was more related to the overall mask/fit versus a problem with the spray. I highly recommend giving this spray a try! How to use: before going into the water, we sprayed a few times into each lens of the mask and rubbed it around. We then used bottled water to swish around in the lenses and rubbed to remove streaks. Then we discarded the liquid and used a towel to blot the excess water inside of the mask. We will use this spray for future trips!

The miracle anti fog !!!

I’ve used this Sea Reef Anti-Fog spray for two swims so far, and it has made a huge difference. You just spray it in, swish it around and rinse with fresh water before your swim.

Used this for some light snorkeling out of a cove. Applied per given instructions and seems to get the job done, you don't seem to need a lot to get everything in. I was able to see just fine with the applied anti-fog during my snorkeling session and for a cheap solution to stay underwater longer this was up to my standard. My only gripe is that after about an hour I would start getting some fogging again and having to clear my mask while in the water. Other than that, this is a solid option for the money.

I have used several brands for laps swimming. This one goes on easy and last 3-5 swims before re-apply is needed.

Tried this for regular glasses which fog up while I'm hiking on humid days. Meh. Still have to sometimes take them off and wipe them, but it is better than nothing at all.

I’ve used $ea G0ld for a long time… at least 10 years, in all types of settings. I don’t know why I tried this product, but it was an AWESOME decision. Make sure to get the spray version, because sometimes the fliptop doesn’t work properly and you get gel all over the place. One day, I arrived at the YMCA without the spray, but it functioned as if I still had a fresh coat on my goggles. Totally worth the loyalty to this product!!!

A must for swimming goggles ,anti fog .

I works

Works but needs to be reapplied daily. Kind of a pain.

Fungerade hur bra som helst på billigare snorkelmask. Bara skölj av ordentligt med vatten innan användning.

Ottimo prodotto

Yo lo uso para tema airsoft y la verdad que va muy bien pero si sudas mucho es verdad que tienes que echarlo otra vez pero cumple bien su función que es que no se te empañan las gafas
