What Temperature to Wash a Wetsuit

Washing your wetsuit properly is just as important as wearing it. The temperature you choose can make the difference between a wetsuit that lasts for years and one that falls apart after a season. The ideal temperature to wash a wetsuit is cold water, between 30 and 40 degrees Fahrenheit (0 to 4 degrees Celsius). This gentle approach protects the neoprene material, maintains the suit's elasticity, and prevents damage to seams and zippers. Most people think any cool water works, but there's actually a sweet spot that keeps your gear performing at its best. Understanding this simple detail can save you money and keep your favorite suits functional for much longer.

Neoprene, the material most wetsuits are made from, is surprisingly sensitive to temperature changes. Hot water causes the rubber to expand and lose its elasticity, which means your suit won't fit as snugly or keep you as warm. Even lukewarm water can gradually break down the material over multiple washes. Cold water, on the other hand, keeps the neoprene stable and maintains its insulating properties. The temperature to wash a wetsuit really does matter because each wash is cumulative. If you use warm water just once or twice, you might not notice much difference. But over a season of regular use, the damage adds up fast. Your seams become more prone to tearing, the material becomes less flexible, and the suit's warmth rating decreases. By sticking to cold water from the start, you're investing in the longevity of your gear. It takes just a few extra minutes to get the water temperature right, and the payoff is a wetsuit that performs like new for years.

Can I use lukewarm water if I can't get the water cold enough?

It's not ideal, but lukewarm water is better than hot water. If your tap water is naturally warm, let it run for a while to cool down, or add ice to a bucket to lower the temperature. Aim for the coldest water you can reasonably achieve. Even a few degrees cooler makes a real difference in preserving your wetsuit's lifespan and performance.

How often should I wash my wetsuit?

Wash your wetsuit after every 3-5 uses, or whenever it smells or feels sticky. Saltwater and sweat break down the material over time, so regular cleaning actually extends the suit's life. If you use it daily, plan on washing it at least once a week. Always use cold water regardless of how frequently you wash.

Is it okay to machine wash a wetsuit in cold water?

Machine washing is risky even with cold water. The agitation and spin cycle can stress seams, stretch the material, and damage zippers. Hand washing in cold water is always the safer choice. It takes about 10 minutes and gives you complete control over how gently the suit is treated.

What happens if I accidentally wash my wetsuit in warm water?

One wash in warm water probably won't ruin your suit, but it will cause some minor damage. The neoprene may lose a bit of elasticity, and seams might weaken slightly. If it happens once, just switch to cold water for all future washes. If warm water becomes a habit, you'll notice your suit fitting loosely and losing warmth over time.

Can I use a hair dryer or fan to speed up drying?

No. Heat from a dryer damages neoprene just like hot water does. A fan on low speed is okay for air circulation, but avoid direct heat sources. Patience is key here. Hang your suit in a well-ventilated area and let it dry naturally over 24-48 hours. The slower the drying process, the better for the material.

Does the water temperature matter for rinsing after washing?

Yes, absolutely. Rinse with cold water just like you use for the main wash. Warm rinse water can undo all the good you did by washing in cold water. Keep everything cold from start to finish, and your wetsuit will thank you with years of reliable performance.
