Product Story
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!

Ingredients
Usage
Directions for Dive Mask & Goggles: Apply a small amount on the inside of the lenses. Use your finger to rub completely over the lens. Add a small amount of water, and rub the defog to remove any streaks. Pour the liquid out when ready to dive. Some bubbles remaining are good. For glasses, safety goggles, ski goggles, sports masks and more: Apply a small amount on the inside of the lenses and lightly rinse or gently buff with soft lens cloth. Our eco-friendly mask defog is made with only the safest ingredients, including Deionized Water, Aloe Barbadensis (Aloe Vera) Leaf Extract and Sodium Lauroyl Methyl Isethionate. Caution: Although this product is formulated with safe and gentle ingredients, avoid direct contact with eyes. If irritation occurs, rinse eyes thoroughly with water. Consult a physician if irritation persists.
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!

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.
TC. –
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.

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!
TH. –
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!!! ❤️♀️

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!
AH. (verified owner) –
Such a great product! I bought this to use on my glasses to prevent fogging when I wear a facemask, and it works AMAZINGLY well!
GA. (verified owner) –
I frequently dive and snorkel, and I defog my mask with a variety of things and I can say that the best defog to date is this one. It remains on for ever and is incredibly clear, unlike some defoggers that irritate my eyes. Additionally, I enjoy that it is environmentally friendly since I’m trying to do everything I can to protect our reefs.
NW. (verified owner) –
I got this product to use on masks I am making/donating to teachers and health care workers. The masks allow for their mouths to be seen while still offering protection. The problem was that the “window” part would fog. I apply this product before delivering the masks so that won’t happen. School starts soon and I was trying to get more of this product quickly. I don’t want the teachers to have to come out of pocket to reapply the product when necessary. I contacted the company asking for the closest brick and mortar store I can go to to get it quickly. They immediately responded with “Give us your address and we will donate some bottles”. So not only is it a great product that is eco conscious and non-toxic that works, it comes from a great company. Highly recommend.
JW. (verified owner) –
It only worked for a couple of hours on my glasses with my mask on.
JC. (verified owner) –
Excellent results with my snorkel mask. I like that it won’t pollute the environment with dangerous chemicals.
JW. (verified owner) –
I have to wear a face mask for 8 to 10 hours a day during this pandemic, and on occasion I also have to wear my reading glasses for computer or close-up work. I decided to try this product because I have been using their hand sanitizer and LOVE it. I appreciate how ecologically friendly their products are. I’m overjoyed with this purchase. I heartily endorse Stream2Sea!
AS. (verified owner) –
I tried this product when a friend of mine recommended it to me. The fact that it performed better than any other product I’ve used surprised me in a good way. Very satisfied with it; won’t switch to anything else in the future.
GM. (verified owner) –
I absolutely love this product, knowing the fact that it is safe for our reefs.
SR. –
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!
GC. –
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.
KW. (verified owner) –
Although I’ve always used soap, a buddy suggested this particular brand as a non-toxic alternative. We spent hours snorkeling California, and I had no difficulties with fogging up. I couldn’t be happier with the results.
RG. (verified owner) –
I like how easy to use this product is.
SR. (verified owner) –
I was unable to rub it well into my lenses.
RG. (verified owner) –
Fantastic result! I snorkeled without thinking about having to reapply for more than an hour.
NH. (verified owner) –
My scuba mask did not fog up when I used this product. It works perfectly!
Brenda (verified owner) –
My husband used this during his seven-hour work shift after I bought it for him. It works and I will be purchasing again
TJ. (verified owner) –
Might work well with scuba masks, but I wouldn’t suggest it for glasses.
AT. (verified owner) –
I use this product as a healthcare professional to prevent my glasses from fogging up.
TT. (verified owner) –
Works great as anti fogging solution.
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!
RZ. –
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.

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.
MM. (verified owner) –
Excellent results each time.

Excellent snorkeling mask defogger

It worked exactly as expected.
AO. (verified owner) –
This product works great!
SM. (verified owner) –
I normally use a baby shampoo for my goggles but since I wanted to be more environmentally friendly, I decided to try this product. When I used it when I was diving, my mask did not stay clear therefore I used the baby shampoo again on my next dive and it worked much better.
SV. (verified owner) –
There was no fog on my swimming goggles when I used it on the pool.
JM. (verified owner) –
My son is using this every time he is swimming and it works great.

This mask defogger really works
GJ. (verified owner) –
Impressive product! Worked like it was supposed to!
AH. (verified owner) –
You only needed a few drops of this product, followed by a quick rinse, to keep your vision clear. When you rinse the glass, be sure to leave a sizable amount of the solution on it.
AH. (verified owner) –
You won’t experience any fogging as long as you remember to reapply before each use. Excellent results and very simple to apply!
AL. (verified owner) –
Goggles must be rinsed to eliminate any excess before use, but they work excellent.
TR. (verified owner) –
This product works great!
CB. (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.

Effectively used in clear masks during pandemics to stop fogging.
BH. (verified owner) –
This has the added benefit of being ecologically friendly and keeps my mask fog-free.
RA. (verified owner) –
This worked great when we used it on snorkeling trip.
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.
HH. (verified owner) –
After swimming for 45 minutes, there is no need for me to reapply this product. It is that long lasting!
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.
TT. –
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.
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.
TW. (verified owner) –
Before leaving on a reef diving tour in the John Pennekamp Coral Reef preserve, I had to make sure I was using high-quality defogger. This product was safe for the reef and worked very effectively.
LT. (verified owner) –
I bought this when I went snorkeling Hawaii. The mask did fog up the first time because I used too much water, but it worked perfectly the second time when I used only a little. I clearly saw every fish! Really fantastic!
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.
TN. (verified owner) –
This works really well. No more fogging!
JL. (verified owner) –
Works perfectly and lasts long.
Robert (verified owner) –
Applying this product once prevented my swimming goggles from fogging up for a long time.
JH. (verified owner) –
My swims often last 45 to 60 minutes. The application will remain in place for the entire duration, and I have not experienced the eye irritation that is usual with other products.
DM. (verified owner) –
Best mask defogger I have used in my 20 years of diving
CW. (verified owner) –
I have no words, I just really love this product.
GC. (verified owner) –
No fog in my glasses today despite the 90 percent humidity, 74 degrees.
RH. (verified owner) –
This is working well so far as long as you follow the instructions.
MJ. (verified owner) –
I’m disappointed because the bottle that I have received is leaking.
TD. –
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
PM. (verified owner) –
I’ve tried a lot of defoggers over the years, and this one is the greatest. Highly advised.
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!
BM. (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.
MT. (verified owner) –
Overall, this product works really great!
CC. (verified owner) –
As said, it works well and easy to apply. No mess at all.
MW. –
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.
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!
KH. (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!!!!
AJ. –
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
MT. (verified owner) –
Trully a great product.
BK. (verified owner) –
I only used it once but it works great so far
DL. (verified owner) –
Besides good ol human-generated spit, and spit doesn’t cut it sometimes. I’ve had divers tell me over and over again that this is the BEST Defog they’ve ever used… And I agree!
I love all the Stream2Sea products for their reef safe guarantee, but the Defog has a special place in my heart for making my life so darn easy. ❤️❤️❤️❤️
Sam (verified owner) –
Worked great!
RS. (verified owner) –
This product works really well and dries pretty quick.
CS. (verified owner) –
I’d always used the spit method until I went on a trip and was sharing my mask. Purchased a random/no name mask defog at a store and it was a waste of money. Did not work and was very frustrating. Purchased from STREAM2Sea for my next trip and it worked every single time! I will never go back to spit or random defogs. Great product!
jonesjr (verified owner) –
Best defog I’ve used in my 36 years of diving!
SW. –
My family purchased this on a dive trip to Bonaire. We did 12 dives each and not once did our masks fog. I am buying 4 more bottles!
JK. (verified owner) –
This is the best defog I’ve used. I’ve tried many and this one by far is the best. Never an issue, mask always stays clear.
DT. –
Awesome
LW. (verified owner) –
It was the first time my mask did not fog so I could actually see! And knowing it does not harm the ocean life made me happy.
AD. (verified owner) –
Stream2Sea’s mask defog is the best I’ve used. Not only does it do exactly what it’s supposed to do, I know it isn’t going to negatively impact the underwater environments that I love so dearly. A small drop goes a long way, too! I’m a lifer.
colleen.lazanich (verified owner) –
This is now the ONLY defog I will use on my masks and all my buddies share too! It never disappoints. And I feel good that it does not harm the environment. Please STOP using baby shampoo!
SH. –
I used this for the first time on a dive trip and several others divers on the boat asked to use it after discovering it worked better than anything they had. This product is absolutely the best.
GD. –
Love this defog it works amazingly and never burn my eyes . Like other products ( spit )
MB. (verified owner) –
I am amazed with this product, my mask if fog free and clear! I have my prescription adhered in my mask and it’s important for me to see. There is no messy residue, goes on clear and clean. I am so glad I tried this product, this will be the my go to and the only defogger that will go in my mask!!

Thanks for sharing, Mark! Glad you love it too 🙂
