I’ll be honest: for the first few years I snorkeled, I treated my fins like old sneakers. A quick shake in the ocean, maybe a splash of fresh water if I remembered, and then I’d stuff them into my gear bag until the next trip. They always seemed fine. Until they weren’t.
One morning off the Kona coast, I noticed my kick felt… off. Sluggish. Like I was pushing through honey instead of water. I was breathing harder than I should have been, and that nagging shortness of breath started creeping in. I cut the session short, frustrated. Back onshore, I took a close look at my fins. The foot pockets were stiff, the blades had a faint white crust along the edges, and there was a smell I’d rather not describe. That’s when I started paying attention—really paying attention—to what I’d been neglecting.
Here’s what I’ve learned since then, and why I think cleaning fins is one of the most underrated skills in snorkeling.
More Than Just Maintenance
When you think about cleaning gear, you probably think about longevity. And sure, keeping salt and sand off your fins means they last longer. But there’s more to it. Every time you take your fins into the ocean, they pick up tiny hitchhikers—microscopic algae, bacteria, even larval organisms. If you travel between different reefs or coastlines, you could be unknowingly transporting those hitchhikers to new environments. It’s a small thing, but conscientious snorkelers care about keeping the places we love pristine.
There’s also a safety angle that surprised me. The 2022 Hawai‘i Journal of Health & Social Welfare study on snorkeling drownings found that increased exertion is a major risk factor for a condition called SI-ROPE (Snorkel Induced Rapid Onset Pulmonary Edema). When your gear doesn’t perform well—when fins are stiff or sand-gritted—you work harder to move. That extra effort adds up. Keeping your equipment in top shape isn’t just about comfort; it’s about keeping your breathing steady and your energy focused on the experience, not on fighting your gear.
What Actually Happens to Your Fins
Seaview 180 designs fins with specific polymers that give them just the right balance of flex and power. But salt crystals are abrasive. When seawater dries on the fin, those crystals form microscopic sharp edges. Every time you flex the fin, they grind against the material. Over months, that grinding makes the surface rough and the blade less responsive. Sand is even sneakier—it gets into the foot pocket, around the heel strap, and under your heel. It causes blisters, chafing, and that annoying slipping sensation. A fin that doesn’t fit right or flex right means you compensate with more muscle, more breath, more stress.
My Five-Minute Routine
I’m no gear obsessive, but I’ve settled into a ritual that takes almost no time and pays back in spades. Here it is:
- Immediate dunk. Before I leave the water, I fully submerge my fins and shake them hard. This gets the loose sand and debris off while everything is still wet.
- Full soak. At the rinse station or in a bucket, I let each fin sit in fresh water for at least five minutes. Not a splash—a full soak. That dissolves the salt crystals hiding in the material.
- Hand cleaning. With my bare hands, I run my fingers along every seam, every ridge, every edge of the foot pocket and blade. I can feel the grit that the soak missed. No brushes, no soap—just water and attention.
- Air drying. I hang my fins in the shade with the foot pockets angled down so water drains out. Sunlight is the enemy of silicone and rubber—I’ve seen fins left in direct sun turn brittle and crack in just a few months.
- Storing flat. I never stack gear on top of my fins or cram them into a tight bag. Deformation can permanently change the blade angle. I hang them by the heel strap or lay them flat.
That’s it. Five minutes. And my fins have never felt better—or smelled better.
A Connection to Something Bigger
One thing the Snorkel Safety Study emphasized is that responsibility for safety lies primarily with the snorkeler. I think that extends to how we care for our gear and our environment. Every time I do that quick rinse and soak, I’m making a small choice to honor the ocean that gives me so much joy. I’m also making sure that if I ever feel short of breath or uncomfortable, it’s not because my equipment is letting me down.
If you experience discomfort, dizziness, or breathing difficulty while snorkeling, exit the water immediately. This gear is designed for recreational surface snorkeling only, and safety depends on proper fit, your health, and responsible use. Always follow the included instructions and warnings.
But honestly? The biggest change was in how I feel about the whole experience. Taking that extra few minutes to care for my fins has become a kind of meditation. A way to slow down after a day on the water, to think about what I saw, and to prepare for the next adventure.
Next time you’re rinsing off, give it a try. Your fins—and your lungs—will thank you.
