“Sea” Clearly with this EcoConscious Mask & Goggle Defog, made with only the safest ingredients for our planet.

  • Reef-friendly, Non-toxic
  • Professional Strength
  • Biodegradable reef safe formula
Tested and Proven Reef Safe, PCR, Fragrance Free

Confession: My spit is defective.  It doesn’t matter how much I prepare my mask, either. I have scrubbed and scrubbed, “toothpasted”, flamed, and scrubbed some more.  I always fog.

So, I jumped into the lab and whipped up a batch using our tested and proven eco-safe ingredients. I like my defog a little more thick and believe the guar gum can also leave a slight film on the lens to help reduce fogging.  It worked great for me, so I started giving out samples to friends and Divemasters – they all loved it!

Our ecosafe Mask Defog is based off of our shampoo that is tested to be biodegradable and safe for fish AND it works brilliantly!  Testimonials have been rolling in that it holds up to multiple dives, and our bottles are sustainably made from sugarcane resins and recycled plastics. Our mask defog is just another way to protect what we love and see clearly while doing so!

  1. Martin W.

    Just tried out the Defog on a trip to the Philippines…longest run was 10 dives (2 days) without reapplying,but I found that a pea size drop on each lens and I didn’t need to put anymore on the rest of the day (5 dives). Plus everyone on the boat tried it and loved it also.

  2. Tonya C.

    This mask defog actually works! It only takes a small amount, so a bottle will last a long time, and it’s in eco-friendly packaging. This product is fantastic- based on my experience with this mask defog, I’m definitely going to be trying more Stream to Sea products in the future.

  3. Christene M.

    I picked up some of the new Stream2Sea mask defog, and brought it with me to Cozumel. Shared it around on the dive boat to get feedback and the results were overwhelmingly positive. Not only is it biodegradable and reef safe, it freaking works. Some said it was even the best stuff they’ve ever used!
    I’ve been a big fan of their sunscreen, hair products, and body wash for a while, and this just shows they really know how to knock it out of the park with quality and sustainability!

  4. Tinamarie H.

    thank you for creating such a wonderful product in your mask defogger … in 30+ dives on this sojourn I have yet to have a foggy mask … this has not happened to me before!! I have shared it with all the people I can on my various dives and it has not failed me. I almost gave my bottle away once but realized “I’m not that nice” and I still had more dives ahead of me If you are someone who sufferes from foggy mask and cares about the ocean and the creatures we want to keep around because that is why we dive … this product will not let you down!!! ❤️‍♀️

  5. Derek F.

    On Saturday I used Stream2Sea Mask defog on an 11 hour exploration cave dive. I was really happy to not have any fogging issues for the entire dive! It’s also awesome that it’s eco conscious and doesn’t added to the pollution of our amazing springs! Thanks Autumn for the awesome product!

  6. S/V R.

    This is the best defog on the market, and I have tested most of them. It keeps your mask clear, doesn’t sting in the eyes, and best of all you can use it knowing you are not harming our beloved reefs!

  7. Gwen C.

    Love this product! I use it on more than just my mask and diving. I use it on eye glasses, goggles, face shields, at work, and more. It does bother my eyes either.

  8. BluberrySea (verified owner)

    I am loving the mask defog! I dive in a very cold environment ( Air -10C and water 1-2C during the winter months) and this product has performed flawlessly. I put some on my mask (and leave it on) when I am getting my gear ready. I give my mask a quick swish in the ocean to acclimatize to the cold as I am entering the water and I am good to go. No fogging, no mask freeze up and no soap in my eyes!

  9. Rose Z.

    Love this defog! I find it works best when I put a very thin coat on my mask while getting my gear ready and let it dry. Because it dries clear, and if I manage to not leave any steaks, I can often jump in the water without the need to rinse off my mask. Works just as well as any other defog I have tried, and this one is safe for all the critters in the ocean. The travel size is perfect to keep in my mask case.

  10. joe.skpllc

    Recently took a trip to a tropical island with shore diving. Applied it before the 1st dive each day and it worked perfectly for several dives all day. Did not irritate my eyes.

  11. Cheryl B. (verified owner)

    Tried the defog before a dive trip to the Bahamas and it worked great. Be conservative with your use and follow the instructions and you will have excellent results.

  12. JW (verified owner)

    This product is amazing and I try to convert every diver, snorkeler and dive operator to switch. Having great luck so far. It really is the best; I dive for multiple hours at a time so it’s great to know I am helping to protect our ocean.

  13. DebDiver (verified owner)

    Finally, a mask defog I can get behind, not only because it is reef safe, it works so well!! I have been giving this away to friends, and hope everyone eventually will find out about this fantastic product.

  14. Thor T.

    Best defog around! Was on a trip with 10 divers in Roatan. By end of day 1 they were all using the Strean2Sea defog. The small bottle is super long lasting, we used it on more than 175 dives and still enough to take home. Nobody wanted anything else, knowing how good it was and that it wasn’t harmful to the reef and the critters on it.

  15. Byron

    I picked this up at a shop in Hawaii and used it just like all the other defog products I have purchased. To my surprise this brand worked my entire dive without fogging. It works the entire dive on every dive. So far as an instructor, this is the only product I have found that really does what it advertises.

  16. Amy (verified owner)

    This stuff is AMAZING! I’ve been diving almost 30 years and have tried every kind of defog out there from my own spit to homemade recipes to other commercially available products. This stuff is 10x better. I have ZERO fogging, even on a dive where my mask was leaking badly. Plus, you only need a tiny drop in each lens, so this bottle will last a long, long time.

  17. Darlene M. (verified owner)

    Best mask defogger I have used in my 20 years of diving

  18. Tom D.

    My family and I have tried a few different products to defog our snorkeling masks and have not been 100% satisfied. We have tried popular brands as well as a defogger made by our local dive shop and then we came across Stream2Sea Defog. My wife and I almost instantly noticed a difference and now are dedicated to Stream2Sea Defog. We also love the fact that it’s biodegradable and safe for our environment. Thank you for a great product. God bless. T

  19. Tryan7283 (verified owner)

    As an avid diver, it’s important for anything I use to be reef safe, that being said, this is the ONLY mask defog that I’ve used that actually works and prevents my dive mask from fogging up. Love this stuff!

  20. Bill M. (verified owner)

    The mask defogger works extremely well. One application normally worked for a few times snorkeling. Everyone on our trip used it an loved how it worked.

  21. Melanie W.

    We received a bottle at a Dive show and are just now trying it out. It is AMAZING! So glad we tried it and are planning for it to now be our “goto” mask defog.

  22. Farrell (verified owner)

    I had been using baby shampoo as defog for 30 years, but the S2S defog is significantly better at keeping the mask lens clear. I’ve never had an issue with eye irritation either. I clean each lens with 1-2 drops of defog, fill the mask with water, and let it sit until I’m ready to dive. Then I dump it out (no rinsing) put the mask on my face and dive dive dive. It works great! I bought more for my friends and family. Thanks S2S for a great product!

  23. Kat H. (verified owner)

    I just returned from a liveaboard trip of snorkeling 4x a day for a week. Yes, the term fanatic fits. The mask defog was fantastic!! 1000% recommended. I will be taking extra bottles with me to Belize to share the news there is a valid alternative to diluted baby shampoo. We must be the change we wish to see in the sea!!!!

    As a dive pro and Mermaid, this is the best defogger that I have used. Received it as a gift at MerWeek2022 from the lovely Mermaid Megan
