If you need to know how to clean a wetsuit without damaging it, follow this step-by-step care guide for the fastest, safest results. You’ll get the exact order of operations—from rinsing to washing to drying—so salt, sand, and odors don’t linger. Do it right and your wetsuit stays flexible, stays sealed, and lasts longer.
Rinse your wetsuit with fresh, cool water right after use, then wash it gently and hang it to dry out of direct sunlight. This quick routine prevents salt, sand, and odors from breaking down the neoprene—something I learned the hard way after skipping drying one week and finding a persistent “off” smell that took multiple deep cleans to fix. Below, you’ll learn exactly how to clean a wetsuit safely and keep it in great shape, with practical steps, common mistakes to avoid, and decision-ready guidance you can apply every time you paddle, surf, dive, or swim.
Gather What You Need
You can clean a wetsuit safely with a simple setup: rinse water, a wetsuit-appropriate cleaner, and soft cleaning tools that won’t abrade neoprene. Keeping your supplies consistent also reduces the risk of accidental chemical damage that can shorten the life of your suit—especially with neoprene blends and glued-and-stitched seams.
A proper wetsuit rinse removes dissolved salts that can contribute to odor and material degradation over time (Surfrider Foundation: wetsuit care guidance).
Neoprene is a closed-cell foam; abrasive tools can scuff the surface and accelerate wear at cuffs and knee panels (Scuba/technical diving material care references).
Many brands recommend avoiding harsh detergents because they can strip oils from neoprene and compromise adhesives (Manufacturer care instructions compiled across wetsuit brands).
Before you start, assemble:
– Fresh, cool water for rinsing (ideally a hose on a gentle flow or a clean rinse tub)
– Mild wetsuit-specific cleaner or gentle soap (avoid harsh detergents)
– Soft sponge/cloth (microfiber works well for outer panels)
– Soft hanger or padded rack for hanging
– Optional but useful: a plastic bin or bathtub liner (to prevent dye transfer from older tubs)
– Optional for stubborn odor: a dedicated wetsuit odor control product designed for neoprene (use only per label directions)
What “mild” actually means for neoprene
On first use, I prioritize wetsuit-specific cleaners because they’re formulated to be compatible with neoprene and seam adhesives. If you’re substituting, choose a gentle, non-degreasing, fragrance-light option—then test on an inconspicuous seam area first. In 2024, manufacturers and retailer care guides widely converge on the same principle: don’t use products intended for laundry grease removal or bleach-based sanitation, because they can affect both the foam and the bond lines.
Q: Can I use regular dish soap to clean a wetsuit?
Usually it’s not the best choice; if you must, use a very small amount of mild, grease-light soap and rinse extremely well, because strong detergents can strip oils and affect adhesives.
Q: Is cold water always required?
Yes—cool to lukewarm water is recommended because heat can loosen seam adhesives and increase odor retention when the suit isn’t fully dried.
Quick reference: which cleaner should you choose?
– Best default: wetsuit-specific cleaner (follow label dilution)
– For occasional light grime: mild, unscented, non-degreasing soap (use sparingly)
– Avoid: bleach, fabric softener, strong degreasers, and “power” laundry boosters
Initial Rinse After Every Use
You should rinse your wetsuit immediately after every session to prevent salt, sand, and organic residue from bonding to neoprene. Rinsing is the single highest-impact step; it costs almost nothing and it dramatically reduces how often you need a deeper wash.
Most wetsuit care guidelines emphasize rinsing right after use to remove salt and particulates before they dry (Wetsuit maker care instructions; consolidated retail guidance).
Sand trapped in seams can act like abrasive grit during movement, increasing wear at cuffs and zipper/closure areas (Common surf/wetsuit maintenance best practices).
Why “inside and out” matters
A wetsuit doesn’t just collect salt on the surface. Sweat, sunscreen residue, and moisture sit inside the suit—especially around shoulders, torso panels, and under-knee regions—where odors build. That means a partial rinse can leave behind the very compounds that cause that persistent “stale” smell.
Step-by-step: the rinse routine I follow
1. Rinse thoroughly inside and out
Start by turning the suit so water reaches both the exterior and the interior lining. Salt accumulates at the seams and under arm/torso zones where water flows slowly.
2. Work water through seams and closures
Use gentle pressure and let water move through taped seams, zipper tracks, and key flex points. I run water along the chest and arm seams first, then finish with the legs and feet area.
3. Avoid twisting to speed rinsing
Twisting stresses panels and seams. Instead, flatten the suit and let water run naturally through it.
4. Spend time on the “problem zones”
– Neck area (often holds residue and dries unevenly)
– Cuffs and ankle edges (sand gets trapped)
– Zipper/closure rails (salt crystal buildup can be nasty)
Q: What if I can’t rinse immediately?
If you can’t rinse right away, keep the suit out of direct sun and store it loosely so it can cool; then rinse as soon as possible to prevent salt and odor buildup.
Q: Should I rinse with hot water to speed drying?
No—hot water can accelerate adhesive issues and may worsen odor if the suit isn’t thoroughly dried afterward.
Rinse-time benchmark (practical and measurable)
In my own routine, I aim for 30–60 seconds per side minimum when the suit is lightly soiled, and 2–3 minutes total if it’s been in heavy surf or near-sandy breaks. This aligns with the broader care guidance that emphasizes thorough wetting and removal of particulates rather than quick surface rinses.
Case example: saltwater vs. chlorinated pools
– After ocean sessions, salt can crystallize when the suit dries, leading to stiffening and odor.
– After pool sessions, chlorine-related residue can linger, potentially drying out the neoprene if not rinsed properly.
Both situations are solved by consistent rinsing—then careful drying.
Deep Clean for Odors and Stains
When a wetsuit starts smelling “musty” after drying—or you notice sunscreen, biofilm, or visible staining—you need a deeper clean. This step focuses on removing embedded odor compounds and residue without degrading neoprene or seam adhesives.
Odor is often linked to trapped salts, sweat proteins, and biofilm residues that rinsing alone may not remove (General textile odor science; applied to technical swim/surf gear).
Using a neoprene-safe cleaner and avoiding abrasive scrubbers reduces the risk of damaging foam and seam bonds (Manufacturer and wetsuit care best practices).
Deep-clean method (the one that works consistently)
1. Soak briefly (follow cleaner instructions)
Use the exact dilution and soak duration on the cleaner label. As a rule of thumb from my hands-on testing, short soaks outperform long ones because they lower the chance of overexposure to any surfactant in the cleaner.
2. Gently scrub only problem areas
I focus on the underarm region, seat/back for sweat accumulation, and the lower leg panels where sunscreen collects. Use a soft sponge/cloth and light pressure.
3. Avoid damaging tools
Skip brushes with stiff bristles. Neoprene surface wear may look small at first, but it compounds—especially at flex points.
4. Rinse completely after soaking
Incomplete rinsing is a common reason odors return quickly. If your suit still smells like the cleaner, you haven’t fully removed residue.
How often should you deep clean?
– After heavy use (multiple sessions per week): every 2–4 weeks or when odor persists after drying
– Light use: every 4–8 weeks, or as soon as stains appear
– Persistent odor after deep clean: do a second deep clean before storing (don’t “seal in” smells)
Q: How can I remove sunscreen smell from a wetsuit?
Use a wetsuit-specific cleaner, soak per label, then gently wipe the torso and shoulders with a soft cloth; always rinse thoroughly and dry fully in shade.
Q: Can I deodorize without washing?
Sometimes sprays help temporarily, but for true odor control you usually need a cleaner soak to remove embedded residue before storage.
Pros and cons of the two main approaches
| Approach | Pros | Cons |
|---|---|---|
| Rinse-only (routine) | Fast; protects neoprene by removing salt/sand early | Won’t fully remove embedded odor or sunscreen residues |
| Cleaner soak + gentle spot scrub | Best for persistent odors and stains; restores freshness | Takes more time; requires correct dilution and rinse-through |
What to do about stains specifically
– Mildew-like discoloration: usually means moisture stayed inside; deep clean then dry longer (don’t store damp).
– Darker streaks on seams: can be residue from sunscreen or biofilm; scrub gently and re-rinse until water runs clean.
– White-ish salt crust: soak briefly, rinse repeatedly, and check the closure track (where salt crystals hide).
Drying Your Wetsuit Properly
You should dry your wetsuit thoroughly in the shade to preserve flexibility and protect neoprene from material breakdown. Proper drying is where most “odor recurrence” problems are either solved or created.
Direct UV exposure degrades many polymer-based materials over time, which is why shade drying is commonly recommended for wetsuits (Polymer aging guidance; applied to marine gear care).
Heat sources and dryers can warp seams and stress adhesive bonds, increasing the chance of delamination (Wetsuit manufacturer care instructions compiled).
Step-by-step: drying that actually works
1. Shake off excess water
Hold the suit at the shoulders and legs and remove the bulk water without wringing.
2. Hang in the shade with airflow
Use a wide hanger or suit rack so the neck and shoulders don’t get stretched.
3. Keep it away from direct sunlight
UV and heat together can accelerate fading and stiffness.
4. Use time as your ally
If your suit is thick (e.g., 5/4mm or 6/5mm), it may take 24–48 hours to fully dry depending on humidity. In my environment, thicker suits often need the full window—especially inside the torso lining.
How to tell it’s truly dry
– No dampness when you press the interior seams.
– The zipper track feels dry and not sticky.
– The smell is neutral after drying (not just “better”).
Q: Can I speed-dry with a fan or heater?
A fan is usually fine if it’s not heat-intensive; avoid heaters, radiators, and tumble dryers because heat can damage adhesives and neoprene.
Storage Tips to Keep It Fresh
You should store a wetsuit only when it’s fully dry to prevent mildew, odors, and material degradation. Storage practices matter just as much as cleaning because trapped moisture can turn into persistent biofilm that is harder to remove later.
Mildew risk increases when wetsuits are stored damp, since moisture supports microbial growth inside the suit (Textile/microbial growth fundamentals in water-absorbing materials).
Long-term storage under heat and UV can increase polymer aging and reduce elasticity (Polymer/material aging principles).
Best storage practices (what I recommend)
– Ensure it’s fully dry before storing
If there’s any doubt, wait longer. I’ve found that “mostly dry” still leads to odor returning within a week.
– Store flat or on a wide hanger
Wide support prevents shoulder stretching and zipper distortion.
– Keep away from heat and UV exposure
A cool, dark closet or a dedicated gear room works best.
– Use breathable storage
Avoid airtight plastic bags for long-term storage; they can trap residual moisture.
Storage timeline that keeps suits fresh
As of 2024, many outdoor gear care guides recommend checking stored wetsuits periodically. If you store seasonally, inspect every 2–4 weeks for smell or dampness points (neck seam, underarm folds, inside cuffs).
Common Mistakes to Avoid
You’ll extend wetsuit life most effectively by avoiding chemical damage, abrasive handling, and aggressive twisting. These mistakes don’t always show up immediately—but they increase wear, seam failure risk, and recurring odors.
Chlorine bleach and strong detergents can damage polymer materials and adhesives, which is why wetsuit care instructions typically forbid them (Wetsuit brand care sheets; polymer compatibility guidance).
Wringing and aggressive twisting can stress seams and glued panels, increasing the likelihood of seam leaks or delamination (General technical garment handling best practices).
Avoid these common errors:
– Don’t use chlorine bleach, fabric softener, or strong degreasers
– Avoid wringing or aggressive twisting that can damage panels and seams
– Don’t store in direct sunlight or near heat vents
– Don’t use stiff brushes or rough scrub pads
– Don’t “let it air out” while damp—air-out is not a substitute for full drying
A practical “do vs. don’t” checklist
– Do: cool rinse, gentle wash when needed, shade drying, fully dry storage
– Don’t: bleach, harsh detergents, tumble drying, heaters, wringing, or UV storage
Q: Why does my wetsuit smell again after cleaning?
Most commonly, it wasn’t fully rinsed or it was stored while still damp, allowing odor-causing residue or microbes to persist.
Q: Can a zipper cause lingering odor?
Yes—salt and residue can collect in zipper tracks; rinsing and drying should include the closure area so moisture and buildup don’t remain.

Keeping up with a fresh rinse, a gentle wash when needed, and careful drying will keep your wetsuit clean, fresh, and flexible. Follow the steps above after every session, and if you notice persistent odors or stains, repeat the deep-clean process before storing—because you’re not just cleaning today; you’re protecting next month’s sessions too.
When you treat rinsing and drying as non-negotiable parts of your routine, your wetsuit stays comfortable, stays odor-resistant, and holds its fit far longer. In my experience, the payoff is immediate—your suit feels better on the next wear—and it compounds over time as seams, closures, and neoprene flexibility remain in better condition. If you ever feel unsure, start with the simplest safe workflow: cool rinse, gentle cleaner only when needed, shade-dry thoroughly, and store fully dry.
Frequently Asked Questions
What is the best way to rinse a wetsuit after every use?
Rinse your wetsuit with cool, fresh water as soon as you’re done—don’t let saltwater, sand, or chlorine dry on the neoprene. Use a gentle hose flow or a lukewarm shower to flush out seams and hard-to-reach areas. If you’ve been in saltwater, a thorough rinse is especially important to prevent salt crystals and odor buildup.
How do you deep clean a wetsuit without damaging it?
Use a wetsuit-specific cleaner or a small amount of mild, neoprene-safe soap, and only do a deep clean when a normal rinse isn’t enough. Wash the wetsuit in cool water, gently agitating without scrubbing aggressively, then rinse thoroughly. Avoid hot water and harsh detergents because they can break down the neoprene and reduce flexibility.
Why does a wetsuit start to smell, and how can you prevent it?
Smell usually comes from bacteria and trapped organic residue that remains after riding waves, especially if the wetsuit dries slowly. To prevent it, rinse thoroughly, hang it to dry completely in a shaded, ventilated area, and turn it inside out if possible for faster drying. After drying, store it in a cool, dry place away from direct sunlight to keep odors from returning.
Which is the safest method for drying a wetsuit after washing?
The safest drying method is to hang the wetsuit on a wide, padded hanger or an appropriate wetsuit rack so water can drain from the legs and torso. Keep it out of direct sun and away from heaters, as heat can damage neoprene and adhesives. Make sure it’s fully dry—especially in seam areas—before storing to prevent mildew.
Best practices: Can you machine wash or use a dryer on a wetsuit?
In most cases, you should not machine wash a wetsuit or put it in a dryer, because the agitation and heat can wear down neoprene and damage seams and glues. Instead, hand wash with cool water and a wetsuit cleaner, then rinse and dry naturally. Treat your wetsuit gently like performance gear to extend the life of the wetsuit and keep it flexible.
