Wetsuit Care: Rinse, Dry & Store

Complete wetsuit maintenance guide — post-dive rinsing, proper drying technique, storage methods, and care mistakes that shorten suit life.

A quality wetsuit is a significant investment that provides three to five years of reliable thermal protection — or one year of declining performance followed by an early replacement, depending entirely on post-dive care practices. The neoprene material, adhesive bonds, stitching, and zipper mechanism that constitute a wetsuit are all degradable by salt, sun, heat, and biological contamination. Every care mistake — sun drying, improper storage, skipped rinses, and aggressive handling — accelerates this degradation. Every correct practice extends functional life and maintains the thermal performance that made the suit worth buying in the first place.

Post-Dive Rinse

Rinse your wetsuit in fresh water after every dive — no exceptions, no shortcuts, no promises to rinse it tomorrow. Saltwater left on neoprene begins crystallizing within hours, and salt crystals embedded in the neoprene cell structure act as micro-abrasives that degrade the material from within during storage and subsequent use. The rinse does not need to be elaborate — a garden hose, a shower, or submersion in a fresh water tub followed by gentle agitation removes the surface salt that causes the most damage. Turn the suit inside out and rinse the interior — body oils, sweat, sunscreen, and urine (acknowledged or not) accumulate on the interior surface and degrade the internal lining that provides skin comfort and warmth retention. A capful of wetsuit shampoo or mild detergent added to a rinse tub every three to four dives removes the organic buildup that plain water leaves behind and keeps the interior lining fresh and functional.

Drying Technique

Hang the rinsed suit on a wide-shoulder wetsuit hanger — never a wire hanger, never a narrow plastic hanger, and never draped over a railing or fence where the fold point bears the full weight of the wet suit. A wet seven-millimeter full suit weighs ten to twelve pounds, and that weight concentrated on a narrow hanger or a sharp railing edge creates permanent deformation in the shoulder neoprene that cannot be reversed once the material has been stretched and compressed beyond its elastic recovery limit. Dry in shade with good air circulation — a covered porch, a garage with the door cracked, or a well-ventilated laundry room all work. Direct sunlight is the single most damaging environmental exposure for neoprene — ultraviolet radiation breaks the chemical bonds in the polymer structure, causing the progressive hardening, cracking, and loss of elasticity that turns a supple new suit into a stiff, cracked shell within a single season of sun drying.

Dry the suit inside out first (interior lining dries faster than exterior rubber skin, reducing the time spent with a clammy interior), then turn right-side out to complete exterior drying. The total drying time depends on suit thickness, air temperature, humidity, and ventilation — plan for twelve to twenty-four hours for a three-millimeter suit and twenty-four to forty-eight hours for a five-to-seven-millimeter suit in typical conditions. Do not use a clothes dryer, heat gun, or radiator to speed drying — heat above one hundred twenty degrees Fahrenheit degrades neoprene adhesives and causes irreversible material damage that shows as delamination, bubbling, and seal separation at bonded seams.

Storage Best Practices

Store the fully dry suit flat or hanging on a wide-shoulder hanger in a cool, dark, dry location away from any source of ozone or UV exposure. Long-term folded storage (stacking a suit in a drawer or packing it in a gear bag between seasons) creates permanent creases in the neoprene that thin the material at the fold lines, weaken the adhesive bonds along seams that cross the fold, and create cold spots where the compressed neoprene provides reduced insulation compared to the uncreased material surrounding it. If hanging space is not available, roll the suit loosely (do not fold) from the legs toward the shoulders, creating a cylinder that distributes pressure evenly rather than concentrating it at fold points where damage occurs.

Store away from chemicals, solvents, petroleum products, and ozone-generating equipment (electric motors, UV sterilizers, some air purifiers) — all of these degrade neoprene through chemical attack on the polymer structure. A closet, a gear room shelf, or a dedicated wetsuit rack in a garage all provide adequate storage environments as long as the space is dry, cool, dark, and well-ventilated.

Zipper Care

The zipper is the most mechanically vulnerable component of a wetsuit and the most expensive to replace if it fails. Rinse the zipper teeth and slider with fresh water after every dive, working the slider back and forth several times during rinsing to flush salt from between the teeth where it crystallizes and creates the grinding resistance that wears the tooth coating and eventually causes slider binding. Apply zipper lubricant (beeswax-based zipper wax or silicone-based zipper lubricant) to the teeth before each dive — lubrication reduces friction, prevents the corrosion that salt promotes between metal teeth, and keeps the slider moving freely through the full range of the zipper track.

Never force a stuck zipper — forcing pushes the slider past an obstruction (sand grain, salt crystal, or misaligned tooth) rather than clearing it, and the force can bend the slider rails or break teeth in the process. When a zipper sticks, stop pulling, apply lubricant to the stuck area, and work the slider gently back and forth through a short range until the obstruction clears. If the zipper consistently sticks at the same point, inspect the teeth at that location for a bent tooth, a missing tooth, or a debris accumulation that requires cleaning before the zipper will function properly across its full range.

Common Care Mistakes

The top five wetsuit care mistakes, in order of frequency and damage potential, are sun drying (UV degradation covered above), skipping rinses (salt crystal embedding that degrades neoprene cells), using the wrong hanger (shoulder deformation from narrow or wire hangers), storing wet (mold and bacterial growth on the interior lining), and aggressive handling (pulling the suit on and off by the neck or wrists rather than rolling it up from the ankles and wrists, which stretches the openings and tears seams at the stress points). Avoiding all five of these mistakes requires no special equipment, no expensive products, and no significant time investment — just consistent attention to simple practices that preserve the suit's performance and extend its useful life from the typical two-to-three-year neglected lifespan to the five-to-seven-year lifespan that proper care consistently achieves.

Neoprene Repair and Patching

Small tears, punctures, and delamination in neoprene can be repaired at home using neoprene cement — a flexible adhesive designed specifically for bonding the closed-cell foam structure of wetsuit material. Clean both surfaces of the tear with fresh water and allow them to dry completely before applying a thin, even coat of neoprene cement to each surface. Allow the cement to become tacky (typically three to five minutes depending on temperature and humidity), then press the surfaces firmly together and hold for thirty seconds. Apply a second coat of cement over the outer surface of the repair to seal the bond and provide a waterproof barrier over the repaired area. Allow twenty-four hours of cure time before diving in the repaired suit. For larger tears or seam separations, a neoprene patch cut from old wetsuit material or a commercial repair patch provides additional structural support behind the cement bond that prevents the repair from re-opening under the flexing and stretching that diving produces.
