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 premium regulator sets through neglect, and budget 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

1. Replace the dust cap on the first stage before rinsing. Water entering the first stage through an open DIN/yoke port is the most common cause of regulator damage. Make sure the cap is dry and seated properly.
2. Soak in fresh water for 15-30 minutes. Don't just run it under a faucet. Submerge it completely.
3. Gently rotate the moving parts while it's submerged so any salt residue rinses off or dissolves.
4. Hang to dry in a ventilated area out of direct sunlight. Don't coil hoses tightly. Let everything drape naturally.

Annual Professional Service

Have your regulators professionally serviced every 12 months or 100 dives, whichever comes first. This typically costs $80-150 depending on brand, parts needed, and your location.

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

• Store with hoses uncurled in a protective regulator bag
• Never hang regulators by the second stage hose
• Keep away from petroleum-based solvents (they destroy rubber components)
• Don't overtighten DIN connections. Hand-tight plus a quarter turn is sufficient

BCD Care

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

After Every Dive

1. Inflate the BCD and rinse the entire exterior. Get into every pocket, strap channel, and D-ring.
2. Fill the bladder partially with fresh water through the oral inflator. Close the mouthpiece and let water flow in.
3. Shake vigorously to distribute water inside, reaching all internal surfaces.
4. Invert and drain through every dump valve. Repeat 2-3 times if you were diving in salt water.
5. Inflate partially (about 30%) and hang to dry on a wide hanger.

Periodic Maintenance

• Inspect the inflator mechanism monthly. Press the inflate and deflate buttons. They should move freely and spring back without sticking. A stuck inflator button underwater is a serious emergency.
• Check dump valve operation. Pull each dump valve and ensure it opens and closes cleanly. Listen for any hissing when inflated.
• Lubricate zippers with wax-based zipper lubricant (not silicone spray). Dry zippers are the number one cause of BCD zipper failure.
• Check for bladder leaks annually. Inflate fully and listen for air escaping. Submerge sections in water to find pin-hole leaks if you suspect one.

Storage

Store partially inflated on a wide hanger in a dry, cool area. Never store deflated and folded. The internal bladder walls can stick together and the folds weaken the fabric.

Wetsuit Care

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

After Every Dive

1. Rinse inside and out in fresh water. Pay extra attention to the inner lining where body oils and sunscreen accumulate.
2. Turn inside out and soak for 10-15 minutes in fresh water. Use wetsuit shampoo (like McNett Sink the Stink) monthly to control bacteria and odor.
3. Hang on a wide padded hanger. Never use wire hangers. The thin wire creates permanent crease damage in neoprene.
4. Dry completely before storing. Partially dry neoprene grows mold.

What Destroys Wetsuits

• Direct sunlight. UV degrades neoprene rapidly. Never dry your suit in direct sun for extended periods. In the shade, draped over a railing, is perfect.
• Heat. Don't leave your wetsuit in a hot car trunk. Heat accelerates neoprene breakdown.
• Folding. Permanent creases compress the neoprene cells, reducing insulation in those spots.
• Wire hangers. They create stress points that thin the material.
• Silicone sprays. Some divers spray silicone to make suits easier to don. This degrades certain glues used in seams and can cause delamination.

Storage

• Hang on a wide padded hanger (surfboard-style hangers work great)
• Store in a cool, dark, dry closet
• Never fold, roll, or compress for storage
• If you must travel with it, roll loosely rather than folding
• Expect 3-5 years of regular use from a quality suit with good care

Zipper Maintenance

Back-zip wetsuits: lubricate the main zipper with beeswax or paraffin every 5-10 dives. A smooth zipper is easier to operate and lasts longer. If a zipper starts catching, don't force it. Clean the teeth with a soft brush and re-wax.

Dive Computer Care

After Every Dive

• Rinse thoroughly in fresh water, paying special attention to the pressure sensor port and buttons
• Press each button several times while submerged to flush salt from around the seals
• Check water contact points for debris, sand, or salt crystals
• Never use compressed air to dry your computer. The blast can force water past seals

Battery Management

Battery failure during a dive trip is preventable: - User-replaceable batteries: Change annually or when the low-battery indicator appears. Always change before a trip, never during. Carry a spare battery and O-ring in your save-a-dive kit. - Rechargeable computers: Charge fully before each dive day. Most last 10-15 hours of dive time per charge, but cold water drains batteries faster. - Non-user replaceable: Send for factory service when the indicator appears. Plan 4-6 weeks for turnaround.

Screen Care

• Don't let other gear press against the screen during transport
• Use a protective cover or screen protector for watch-style computers
• Clean with a soft cloth, never abrasives

Mask Care

New Mask Prep

Critical step most divers skip: New masks have a thin film of silicone residue from manufacturing. This causes persistent fogging no matter how much anti-fog you use. Before your first dive: 1. Apply a small amount of non-gel toothpaste to the inside of both lenses 2. Scrub gently with your fingers for 30 seconds per lens 3. Rinse thoroughly 4. Repeat 3-4 times

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

After Every Dive

• Rinse in fresh water, including the strap and buckle mechanism
• Store in a hard case or mask box (never loose in a gear bag)
• Keep the silicone skirt away from direct sunlight (UV degrades silicone, causing yellowing and loss of flexibility)
• Don't rest anything on top of the mask. Pressure on the skirt causes permanent deformation

Anti-fog Options

• Commercial anti-fog: Products like Sea Gold or Sea Buff work well. Apply, rub, and do a quick rinse before diving.
• Baby shampoo (diluted): A few drops rubbed on lenses works as a budget alternative. Some divers carry a small bottle in their save-a-dive kit.
• Spit: The original method. Still works. Less effective than commercial products but always available.

Fins and Booties

Fins

• Rinse in fresh water after every dive
• Check strap buckles and springs for corrosion
• Store flat or hanging, never standing on blade tips
• Full-foot fins: check the heel pocket for cracks periodically

Booties

• Rinse inside and out (they trap sand and debris)
• Dry completely between dives to prevent odor and mold
• Turn inside out periodically for thorough drying
• Replace when soles wear thin. Slippery booties on a wet boat deck are a genuine safety hazard

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

An inexpensive 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.
