The Ultimate Guide to Conquering Diving Mask Fog

The weird things you find when Snorkeling

A foggy mask is every snorkeler’s arch-nemesis. It ruins the view, kills the vibe, and turns a perfect adventure into a blurry mess of frustration. Picture this: you’re snorkeling over a stunning coral reef, ready to capture the most epic underwater videography footage of your life—and BAM! Fog. You’re now staring at your own confused reflection instead of that majestic sea turtle. 😑

Not today, fog beast. Today, we slay the diving mask fog.

I’m testing SEVEN different anti-fog methods to find out which one reigns supreme. But let’s make things interesting:

7 methods. 7 days. One determined snorkeler.

Come rain, storm, or blazing sun, I’ll be out there, mask on, camera rolling, putting these hacks to the test. Let’s dive in! 🌊🎥

I have created a video showing me testing all the methods:

Method 1: The Good Ol’ Spit Method 🤢

Application: ✅ Easy to apply

Availability: ✅ Free (unless you charge for your own spit—no judgment)

Effectiveness: ❌ Meh, not great

Ah, the most ancient anti-fog trick in the book. Just hock a loogie into your mask, rub it around, rinse, and go. The problem? It’s hit-or-miss. Sometimes it works, sometimes your mask still fogs up like an overboiled kettle. Plus, if you’re filming underwater videography, do you really want to be rubbing saliva all over your precious lens? Yeah, me neither.

Method 2: Toothpaste (Yes, Really) 🦷✨

Application: ✅ Easy to apply

Availability: ✅ Cheap and easy to find

Effectiveness: 🔥 AMAZING

Who knew your pearly whites and your dive mask could share the same secret weapon? A tiny dab of toothpaste (non-gel) scrubbed onto the lens, left to sit, then rinsed off, creates a fog-resistant barrier. My mask stayed clear for ages! Highly recommend it for both snorkelers and underwater videographers who want their shots crisp and fog-free.

Method 3: Potato Power 🥔

Mask full of potato oil. Ew

Application: ❌ Difficult (unless you carry a potato around?)

Availability: ✅ Cheap and easy to find

Effectiveness: 🔥 Shockingly Amazing

Yes, you read that right. You slice a raw potato and rub it on the mask lens. The natural starch creates an anti-fog layer. I felt ridiculous doing this, but I can’t lie—the results were incredible. The downside? Who’s realistically bringing potatoes on a dive trip? If you do, respect. 😂

Method 4: Baby Shampoo 🍼🚿

Application: ✅ Super easy

Availability: ✅ Cheap and everywhere

Effectiveness: 🔥 Fantastic

A few drops of baby shampoo + water, rinse, and BOOM—no fog at all. Plus, it smells nice. Just don’t go overboard, or you’ll spend the dive looking like you lost a fight with a bubble bath. This is a pro choice for serious underwater videographers who want zero fog distractions while filming.

Method 5: Burn It. Literally. 🔥🔥🔥

Burning your diving mask might be scary. But its effective

Application: 😬 Medium difficulty (involves fire)

Availability: ✅ Easy (if you own a lighter)

Effectiveness: 🤯 AMAZING

This method is as hardcore as it sounds. You take a lighter and carefully burn the inner glass surface of the mask to remove factory coatings that cause fogging. It works like magic—but it also feels like you’re performing an ancient snorkeling ritual. Pro tip: Don’t try this on plastic lenses, unless you enjoy molten disasters.

Method 6: The Legendary Anti-Fog Spray (If You Can Find It) 💸

Application:❓ Unknown

Availability: ❌ Extremely Difficult

Effectiveness:❓ No idea—I couldn’t even find one!

Some say it exists. Some say it’s a myth. I checked every dive shop on this island—a place where people literally dive for a living—and still, no anti-fog spray to be found. If it’s this hard to get, should you really rely on it? Probably not. If you ever come across this elusive spray, grab it and consider yourself lucky. But until then, let’s stick to solutions that actually exist… like potatoes.

Method 7: Dishwashing Liquid 🧼

Application: ✅ Super easy

Availability: ✅ Everywhere

Effectiveness: 🔥 Great

A drop of dish soap, rinse, and goodbye fog! Cheap, simple, and highly effective. Just don’t go overboard—you don’t want your snorkeling trip to turn into an impromptu bubble-blowing contest.

The Verdict: The Diving Mask Fog slayer is: 🏆

After 7 days of snorkeling through sun, rain, and questionable life choices, here’s my ranking from best to worst:

1️⃣ 🔥 Burn the mask – Most effective (but not for plastic lenses!)

2️⃣ 🦷 Toothpaste – Easy, cheap, and insanely good

3️⃣ 🍼 Baby Shampoo – Works great and smells nice

4️⃣ 🥔 Potato – Who knew? Weird, but effective

5️⃣ 🧼 Dish Soap – Solid option, just rinse well

6️⃣ 🤢 Spit – Meh. Works when it wants to

7️⃣ 💸 Anti-Fog Spray – If you can even find it, let me know!

If you’re serious about snorkeling and underwater videography, don’t let a foggy mask ruin your shots. Try these hacks, and keep that mask crystal clear so you can film every epic underwater moment. 🎥🐠✨
