San Diego Freediving Equipment: Rinse and Storage Best Practices

San Diego’s kelp forests, rocky reefs, and clear summer waters make it one of the best freediving destinations on the West Coast. But the same saltwater, UV exposure, and mineral deposits that make our conditions world-class will degrade your equipment fast if you don’t maintain it properly. Proper rinse and storage routines aren’t optional—they’re the difference between gear that lasts years and gear that fails when you need it most.

Why Salt and Sun Damage Freediving Gear

Saltwater is corrosive. After a session at Bird Rock, La Jolla Shores, or any of San Diego’s prime freediving spots, salt crystals embed themselves in neoprene, metal hardware, and rubber seals. Left unrinsed, they draw moisture, accelerate material breakdown, and create weak points in your wetsuit and fins.

UV exposure is equally destructive. San Diego’s 260+ days of annual sunshine mean relentless UV radiation. Neoprene degrades under UV; rubber cracks; adhesives weaken. A wetsuit stored in direct sunlight loses elasticity and strength far faster than one kept in shade.

Temperature swings also matter. Your gear expands in heat and contracts in cold. Improper storage in a hot garage or exposed truck bed creates stress cycles that crack seams and delaminate neoprene.

The Rinse Protocol: Fresh Water First, Always

Rinse immediately after every session. Don’t wait until you get home. If you’re diving at Sunset Cliffs, Bird Rock, or the Coronado Islands, rinse at the nearest freshwater source or bring a rinse bottle in your truck.

Use fresh water—not tap water treated with chlorine. Chlorine can degrade neoprene and rubber over time. If your local beach access only has chlorinated showers, use it, but follow up with a dedicated freshwater rinse at home. Many San Diego freedivers keep a 5-gallon bucket of fresh water in their vehicle for quick post-dive rinses.

Rinse all gear thoroughly:

• Wetsuits: Rinse the inside and outside. Turn sleeves and legs inside-out to flush trapped salt and sand.
• Fins and mask: Pay special attention to the strap attachments and mask skirt—salt accumulates in crevices.
• Weights and belts: Rinse metal buckles and weight pockets completely.
• Snorkel: Flush the interior to remove salt residue.
• Weight harness or integrated weights: If you use a weight integrated suit, rinse the pockets and seams.

Soak if heavily salted. After a particularly salty day—especially if you’ve been in the water multiple times—soak your gear in a tub of fresh water for 15–20 minutes. This dissolves salt crystals embedded deep in the material.

Drying: Low Heat, No Direct Sun

Hang, never wring. Wringing out wetsuits stresses seams and can cause delamination. Instead, gently squeeze excess water and hang the suit on a wide, padded hanger. Hang it inside-out first to dry the interior, then flip it.

Dry in shade, ideally indoors. A garage, basement, or shaded covered area is ideal. If you must dry outside, use a shaded patio or under a carport. Never leave gear in direct sun—the UV and heat will damage it faster than you can rinse it.

Allow 24–48 hours for complete drying before storing. A damp suit stored in a bag or locker will develop mold and mildew, especially during San Diego’s humid summer months.

Dry fins and masks separately. Stand fins upright or lay them flat on a towel. Place masks face-down on a soft surface to avoid scratching the lens. Never store a wet mask in a bag—the skirt will degrade.

Storage: Cool, Dark, and Well-Organized

Store in a cool, dark place. Your bedroom closet, a basement shelf, or a climate-controlled storage locker is perfect. Avoid hot attics, sun-exposed garages, or vehicles. Ideal storage temperature is 50–70°F; humidity should be moderate (not damp, not bone-dry).

Hang wetsuits on padded hangers. This prevents creasing and allows air circulation. Never fold a wetsuit for long-term storage—creases become weak points.

Store fins flat or upright, never bent. Bent fins develop permanent kinks that affect your kick efficiency. Lean them against a wall or lay them flat in a designated storage bin.

Keep masks in a protective case. Use a padded mask bag or hard case to prevent the lens from getting scratched and to keep dust off the skirt.

Store weights separately. Metal weights should be dry and kept in a cool place. If you use a weight belt, hang it up rather than coiling it tightly.

Use breathable storage bags, not plastic. If you bag your wetsuit, use a mesh gear bag that allows air circulation. Plastic bags trap moisture and promote mold growth.

Organize by season. San Diego’s water temperature ranges from 57°F in winter to 72°F in summer. Keep your 5mm suit accessible in winter (November–April) and your 3mm or rashguard in summer (June–September). Spring and fall require flexibility, so keep both options ready.

Maintenance Checks: Monthly

Every month, inspect your gear for damage:

• Check seams for separations or stress cracks.
• Look for neoprene delamination or soft spots.
• Test zipper function and lubricate with a silicone-based zipper lubricant if needed.
• Check fin foot pockets for cracks or deterioration.
• Inspect mask seals for hardening or cracks.

Catch problems early. A small seam separation is an easy fix; ignoring it leads to a flooded suit at depth.

Final Thoughts

Your freediving gear is your lifeline in San Diego’s waters. Treat it with the same respect you’d give your body. A few minutes of post-dive care extends equipment lifespan from 2–3 years to 5–7 years, saving you money and keeping you safer in the water.
