How to Fix a Stuck Wetsuit Zipper (And Prevent It)
Why Wetsuit Zippers Get Stuck
Wetsuit and drysuit zippers face unique challenges:
- Saltwater corrosion: Salt crystals build up on metal teeth and cause friction
- Sand and debris: Beach sand acts like sandpaper between zipper teeth
- Material stress: Neoprene expands and contracts with temperature changes
- Lack of lubrication: Factory lubricant wears off after repeated use
Emergency Fix: Unstick Your Zipper in 2 Minutes
-
Rinse with Fresh Water
Immediately rinse the zipper with fresh water to dissolve salt crystals. Use lukewarm water if available. Avoid pulling on a stuck zipper without rinsing first.
-
Apply Silicone Lubricant
Spray or apply silicone-based lubricant (like Gear Aid Zipper Cleaner) on both sides of the zipper teeth. Wait 30 seconds for it to penetrate.
-
Work the Slider Gently
Move the slider up and down slowly, applying gentle pressure. Don't force it. If resistance is high, add more lubricant.
-
Check Alignment
Ensure both sides of the zipper tape are properly aligned at the bottom. Misalignment is the #1 cause of stuck zippers.

Professional Tips from Divers
Pro Tip #1: Store your wetsuit with the zipper fully open. This reduces tension on the slider and extends zipper life.
Pro Tip #2: Before lubricating, use a soft toothbrush to remove salt buildup. This makes lubricant penetrate better.
Pro Tip #3: If you surf in cold water frequently, lubricate your zipper the night before your session. This prevents the lubricant from washing off immediately.
When to Replace vs. Repair
✓ Can Be Fixed:
- Zipper feels stiff but works
- Minor salt corrosion
- Slider moves but needs force
- One or two teeth are slightly bent
✗ Needs Replacement:
- Multiple missing teeth
- Zipper splits open when closed
- Slider is cracked or broken
- Fabric tape is torn or separating
Replacement Cost: Professional wetsuit zipper replacement typically costs $40-80 depending on zipper type. Heavy-duty waterproof zippers (like YKK Aquaseal) cost more but last longer.
FAQ: Wetsuit Zippers
No. WD-40 contains petroleum distillates that can degrade neoprene and damage waterproof seals. Always use silicone-based or wax-based lubricants designed for wetsuits.
Soak the zipper in warm fresh water for 10 minutes. Use a soft toothbrush to gently scrub both sides of the teeth. Rinse thoroughly and let it dry before applying lubricant.
Yes. Drysuit zippers are typically brass or plastic and respond well to the same silicone or beeswax lubricants. Brands like McNett specifically make products for drysuit zippers. Apply lubricant to the outside (non-seal side) only.
