Dive Gear Maintenance Guide 2026 | Care for Your Equipment

Looking for more gear recommendations?

Proper care extends your gear's life by years and keeps you safe underwater. divers have destroyed $3,000 regulator sets through neglect, and $400 setups have lasted a decade with consistent care. The difference isn't the gear. It's the maintenance.

The complete maintenance guide for every piece of dive equipment you own.

The Golden Rule

Rinse everything in fresh water after every dive. Salt water is corrosive. Chlorine is corrosive. Even lake water leaves mineral deposits. A 15-30 minute soak in fresh water after every dive is the single most impactful thing you can do for your gear's longevity.

This isn't optional. It's not something you do "when you remember." Build it into your post-dive routine the same way you log your dive. Every single time.

Regulator Care

Your regulator is life-support equipment. Treat it accordingly.

After Every Dive

Annual Professional Service

What happens during a service: - Complete disassembly of first and second stages - Inspection of all O-rings, seats, and springs - Replacement of worn parts (diaphragms, exhaust valves, seat discs) - Reassembly to manufacturer specifications - Intermediate and final pressure testing - Breathing effort (cracking pressure) adjustment

Most manufacturer warranties require annual service. Skip it and you void the warranty. More importantly, skip it and you risk equipment failure at depth.

Warning signs requiring immediate service: - Difficult breathing or unusual resistance on inhalation - Free-flowing at surface or depth (continuous air leak from second stage) - Air leaks from any hose connection or swivel - Moisture or unusual taste in your air supply - Sticky inflator buttons that don't return fully

Between Services

BCD Care

BCDs have moving parts, fabric, and an internal bladder that all need attention.

Periodic Maintenance

Storage

Wetsuit Care

Neoprene degrades from UV exposure, heat, and compression. Most wetsuits die from storage neglect, not diving.

This removes the factory film. Skip this step and you'll fight fog for months.

The Save-a-Dive Kit

Every diver should carry one. Essential contents:

• Spare mask strap and fin straps
• O-rings (regulator and computer sizes)
• Silicone grease
• Cable ties (multiple sizes)
• Small adjustable wrench
• Spare mouthpiece for second stage
• Anti-fog solution
• Spare computer battery (if user-replaceable)
• Wetsuit cement for small tears

A $30 save-a-dive kit has rescued more dive trips than any piece of expensive gear. Keep one packed and in your dive bag permanently.

Seasonal Storage

If you're storing gear for winter (or any extended period):

1. Clean everything thoroughly using the methods above 2. Dry completely. Moisture plus months equals mold, corrosion, and rubber degradation 3. Store regulators with dust caps sealed, in a regulator bag, with hoses loosely coiled 4. Store BCDs partially inflated on wide hangers 5. Store wetsuits on wide hangers in a dark closet 6. Remove batteries from dive lights to prevent corrosion 7. Store computers with displays visible so you can check for low-battery warnings

Our Top Tip

Create a post-dive routine and follow it every single time. Write it on a waterproof card and keep it in your gear bag if you need to. Gear failure almost never results from defective equipment. It results from the dive where you were tired, in a rush, and thought "we'll rinse it tomorrow."

Tomorrow never comes. Rinse it today.

Annual Maintenance Checklist

Print this, put it in your gear bag, and work through it once a year -- ideally before the season kicks off.

Regulator - Send for annual service by a certified technician (non-negotiable for life-support equipment) - Inspect hoses for cracking, bulging, or abrasion marks -- replace any that show wear - Check mouthpiece for tears; replace if damaged - Confirm dust cap seals properly and is in good condition

BCD - Fully inflate and leave overnight -- any deflation indicates a bladder leak needing repair - Test all dump valves individually; sticky or non-functioning valves need servicing - Inspect all buckles, D-rings, and straps; replace worn or cracked hardware - Check the oral inflation valve seals correctly

Wetsuit - Inspect all seams -- repair minor separation with neoprene cement before it worsens - Check zip operation and lubricate with beeswax or dedicated zip lubricant - Inspect for neoprene compression loss; areas that feel significantly thinner are worn out - Clean inside with wetsuit shampoo to remove body oils that degrade neoprene over time

Mask and Fins - Inspect mask skirt for tears, hardening, or discoloration - Check fin foot pocket for cracking or stiffness - Inspect fin blade for stress fractures at the connection point -- this is where fins break

Dive Computer - Check battery level; replace before the season if below 50% - Inspect screen for scratches or fogging -- fogging indicates seal failure - Update firmware if manufacturer releases updates

This takes two to three hours when done properly. That two hours directly correlates to gear that works reliably for another 12 months. The alternative -- discovering a failed BCD bladder or a sticky dump valve at the dive site -- costs you a day's diving, potentially a trip, and the embarrassment of standing on the boat in full kit unable to enter the water. Maintenance is an upfront investment that pays back every time you roll in without incident.
