Wetsuit Care and Maintenance Guide (UK)

Looking for more gear recommendations?

A quality wetsuit costs around £200-400. With proper care, it lasts 3-5 years of regular cold water diving. Neglect it, and you're buying another in 18 months. This is how to maximise your investment.

Quick Reference

*Proper care adds years to your wetsuit's life*

Post-Dive Rinse: Essential

After every dive:

1. Rinse outside first to remove sand and debris.

2. Turn inside out and soak in fresh cool water for 10-15 minutes.

3. Pay attention to zippers, seals, and seams where salt accumulates.

4. For shore dives with mud or silt, pre-rinse at site, then thorough clean at home.

5. Never use hot water. Heat damages neoprene.

Cold water diving means salt water. Salt crystals left in neoprene accelerate degradation and cause that distinctive smell everyone pretends they can't notice in the car park.

Monthly Deep Clean

Every month during active diving season:

1. Fill bathtub with cool fresh water.

2. Add wetsuit shampoo (around £5-15 for a bottle lasting months).

3. Soak suit inside out for 15-20 minutes.

4. Gently agitate to release trapped residue.

5. Rinse thoroughly in fresh water.

6. Dry completely before storage.

Wetsuit shampoo maintains neoprene flexibility and removes body oils that degrade material. Regular cleaning extends suit life significantly.

Proper Drying

The British climate makes drying a challenge in itself:

Hang inside out on wide plastic hanger in ventilated area.

Allow 24-48 hours for complete drying. British humidity extends this.

Never use radiators, tumble dryers, or direct sunlight.

Once inside is dry, turn right-side out and hang for another 12-24 hours.

Check carefully before storage. Any trapped moisture causes mould and smell.

Storage Between Dives

Short-term (days): Dry completely, store on wide hanger or loosely folded.

Season storage: Clean thoroughly, dry completely, hang on padded wide hanger in cool, dark, dry space. Bedroom wardrobe works well.

Avoid: Folding (creases damage neoprene), car boot storage, damp garages, direct sunlight.

Zipper Maintenance

Back zippers fail more often than any other wetsuit component.

After rinsing: Run zipper open and closed several times to prevent salt crystal buildup.

Monthly: Apply zipper lubricant or beeswax to both sides of teeth.

Before each dive: Check zipper pulls and stitching for wear.

Cost of zipper replacement: Around £65-150. Cost of prevention: minutes per month.

Small Repairs

Handle small tears immediately. They grow rapidly once started.

For punctures and small tears:

1. Clean and dry the area completely.

2. Apply neoprene cement to both surfaces.

3. Wait until tacky (5-10 minutes).

4. Press firmly together and hold for 2-3 minutes.

5. Allow 24 hours cure before use.

Repair kits cost around £10-15 from dive shops. They're worth having in your kit bag.

When to Replace

Consider replacement when:

Neoprene has lost significant flexibility (feels stiff, doesn't stretch)

Multiple repairs are failing

Seals no longer maintain seal (water flushing constantly)

Fit has degraded (stretched out, uncomfortable)

Suit no longer keeps you warm

A well-maintained suit lasts 3-5 years of 30-50 dives annually. Some divers get longer; it depends on care quality.

Seasonal Considerations

Spring: Full clean before season. Check all seals and repairs.

Summer: Regular post-dive rinse. Monthly deep clean during active diving.

Autumn: Deep clean before storage. Repair any damage.

Winter: Store properly. Check monthly for mould.

Wetsuit Cleaning Products

Several products help maintain neoprene quality beyond basic rinsing.

Wetsuit Shampoo (£5-15) Brands like McNett Sink the Stink, Gear Aid, and Stream2Sea offer specialised formulas. They remove body oils, neutralise odours, and condition neoprene. Worth the small investment.

Neoprene Conditioner (£10-20) Specialised conditioners restore flexibility to aging neoprene. Apply annually or when suit feels stiff. Can extend suit life by 1-2 years.

Zipper Lubricant (£5-10) Beeswax-based or silicone lubricants prevent zipper corrosion and jamming. Apply monthly during diving season. Prevents the most common wetsuit failure point.

DIY Alternatives Baby shampoo works for basic cleaning. Beeswax candles can substitute for commercial zipper lubricant. However, dedicated products perform better for long-term care.

Common Wetsuit Problems and Solutions

Knowing how to address issues early prevents expensive replacements.

Persistent odour despite cleaning: The smell comes from bacteria in trapped moisture. Soak in diluted antiseptic mouthwash (Listerine works) or use specialised antibacterial wetsuit cleaner. Ensure complete drying afterward.

Stiff, inflexible neoprene: Often indicates compression or UV damage. Apply neoprene conditioner generously. Store properly on wide hanger to prevent further compression.

Peeling or flaking lining: Usually indicates sun or heat damage. No repair possible once started. Prevent by avoiding direct sunlight and never using tumble dryers or radiators.

Water flushing through seals: Seals lose effectiveness over time. Some can be re-glued; severe cases need professional repair or suit replacement. Test seals by filling suit with water and checking for drainage.

Zipper failure: Often caused by salt crystal buildup. Clean zipper teeth with toothbrush and fresh water. Lubricate regularly. Stuck zippers may need professional repair.

Wetsuit Challenges

British diving presents unique care challenges compared to tropical use.

Salt and silt combination: Dive sites often combine salt water with silty conditions. This mixture is more abrasive than pure salt water. Rinse more thoroughly.

Longer drying times: British humidity means suits take longer to dry. Budget 48+ hours for complete drying. Consider a dedicated drying area with good ventilation.

More frequent use of thick suits: 7mm suits take longer to dry and are harder to store than thin tropical suits. Invest in proper wide hangers.

Thermal cycling: British weather causes temperature swings even in storage. Store in stable environment to prevent material stress.

Our Recommendation

Ten minutes after each dive. That's all it takes. Monthly deep clean during diving season, proper storage, and your £300 wetsuit lasts 4-5 years instead of 18 months. Your regulator needs similar discipline. Look after your kit and it looks after you.
