How to Wash a Wetsuit Because They Require Simple (But Very Specific) Care

How to Wash a Wetsuit Because They Require Simple (But Very Specific) Care

Avid surfers, divers, and open-water swimmers all count on their beloved wetsuits to keep them warm, last a long time, and, most importantly, help them perform at their best in the water. Wetsuits can be a sizable investment, and when you make that kind of purchase, you definitely want to take care of it so it can last you many trips to the beach, perfect waves, and dazzling scuba trips.

When it comes to taking care of your wetsuit, proper cleaning and careful storage are paramount. To understand why wetsuits require intentional care, it can help to understand what they're made of and why. Wetsuits rely on laws of thermodynamics to keep the wearer warm and wet (but not too wet). Wetsuits are made of three distinct layers. Because of these layers, that we will explain in a moment, Dirty Labs Bio Enzyme Laundry Detergent is uniquely equipped to cleanse your wetsuit of built up environmental grime and bodily secretions like sweat and sebum. This is because the Bio Enzyme formulation is comprised of active cleaning molecules that get into the complex fabrics of wetsuits. This action happens primarily during the soaking stage — which is why soaking is so important.

What Is a Wetsuit Made Of?

●  Outer fabric: The outer layer of a wetsuit is made of durable nylon, polyester, or spandex. It protects the inner foam core from wind, cuts, and UV.

●  Middle foam core: Wetsuits have a central neoprene (synthetic rubber) core to carry out their main purpose of insulation. Some suits can also have a plant-based foam like Yulex. These materials are filled with tiny bubbles of nitrogen to trap body heat inside the suit (against your skin) and provide that squishy buoyancy that gives wetsuits their classic bulk.

●  Inner lining: Most wetsuit inner linings are made of polyester or nylon designed specifically to allow the suit to slide on easily and promote heat retention by allowing some water into the suit to heat up and keep you warm.

These three layers of the suit require specific care to keep them from smelling bad, breaking down over time, or failing to keep you warm out there when you're catching some sick waves.

●  Make sure to fully dry it and store it properly.
●  Use gentle, eco-friendly products like Dirty Labs' Bio Enzyme Laundry Detergent to protect the materials and the environment.

1. Rinse It Immediately After Use

After you're done with your dive, scuba, or surfing, you want to rinse the suit with fresh, clean, cool water. This can rinse away the salt water, grime (because even the clearest bodies of water have silt, bacteria, algae, and stuff you don't want sinking into your suit for good), sweat, and sunscreen. Agitate or gently scrub the areas you sweat the most with your fingers as you rinse them. This can be done at home with your hose, or you can bring some water for rinsing your suit when you get back to your car.

2. Dose and soak the suit properly 

Fill a kiddie pool, bath tub, or plastic storage tub with cold or cool water and add a wetsuit-specific cleaner and dose according to its directions. For this deep clean, you can use Dirty Labs Bio Enzyme Laundry Detergent.

For a pool or tub full of 25 gal water:

• Lightly soiled: 1 tsp (5ml or 0.2ml/gal)
• Average soil: 2 tsp (10ml, 0.4ml/gal)
• Heavily soiled: 3 tsp (15 ml, 0.6 ml/gal)

[Do not use booster for your wetsuit]

“The neoprene and the rubber are not very stable materials and can therefore be easily damaged by surfactants and bleaches,” says Dr. He. “That's why it has to be cleaned with cold water, dosed correctly with a safe formula and set to air dry in the shade. I would suggest that preferably use our Free & Clear or Hand Wash &  Delicates formulas. Also avoid using our booster because of the high pH and oxygen bleach in it.”

To do this, turn the wetsuit inside out and gently work the cleaner through the neoprene. Scrub the material gently and let the water in the tub get really dirty (that's how you know you're getting a good clean).

Rinse thoroughly until no cleaner remains in the suit and you're no longer getting suds. You will know that it's ready to dry when your rinse water is running super clear.

3. Rinse and Repeat

Once you have dosed the tub of water with your detergent, turn the wetsuit inside out and gently work the solution in the tube through the neoprene. Scrub the material gently and let the water in the tub get really dirty (that's how you know you're getting a good clean). Once your wetsuit is submerged and scrubbed, let it soak for 10 to 20 minutes (30 minutes if it is really stinky). Avoid soaking it for hours or overnight because you don’t want the adhesive on the seams to be weakened by the detergent, though the Dirty Labs Bio Enzyme Hand Wash and Delicates Detergent is the gentlest and safest option you could choose for your suit. 


Rinse thoroughly until no cleaner remains in the suit and you're no longer getting suds. You will know that it's ready to dry when your rinse water is running super clear. If you continue to get grey or dirty water on your rinses, you can feel free to repeat the process again. Once the water is running clear during your rinses you’ll know that all that gunk you accumulate while catching sick waves has gone down the drain. 

4. Dry It Properly 

Once you’ve completed the washing process, hang the wetsuit inside out to dry in a shaded, well-ventilated area. You don't want to drape your wetsuit in direct sunlight because the heat can age the suit over time and damage the adhesive or neoprene.

When you hang your suit to dry, you should consider getting wide-armed hangers that support the shoulders of the suit. Regular hangers can cause dents or even holes in the shoulders of your suit over time because of the weight of this particular garment.

If you don't have a proper hanger, drape it over a railing or clothesline by the waist of the suit to protect the material from being gouged.

What to Avoid When Washing Your Wetsuit?

• Manufacturers usually recommend handwashing and never using a washing machine or dryer.
• Even if your wetsuit is super smelly, you shouldn't use bleach, regular detergent, or fabric softener on the suit. 
• Avoid hot water unless the manufacturer's instructions suggest otherwise, as this can damage the neoprene core or seams of the suit.

What to Do If Your Wetsuit Smells, Like, Really Bad?

Enzyme-driven detergents like Dirty Labs are the perfect solution for persistent odors. They are active cleaners that can get into the complex fabrics like neoprene to break down stains that odor causing bacteria love to live on. Depending on how bad the odor is, this could take a few rounds of soaking and rinsing in our Bio Laundry Detergents.  

They can also benefit from an extra-long soak, as long as your manufacturer's instructions allow that. Smelly suits usually point to a flaw in your care process, so make sure you're always rinsing the suit after you use it, letting it dry thoroughly before storing it in a well-ventilated container or area.

How to Store a Wetsuit

Storing a wetsuit is a huge part of its care and preserving its longevity. You should store the suit in a dark, cool, dry place away from direct sunlight. This means you really shouldn't leave it in a car or gear bag. When you hang the suit up, make sure to use appropriate hangers so that the stress of the suit's weight on a slim hanger won't damage the shoulders over time. The best way to store the suit is hanging, because prolonged creasing in a bag can put stress on the foam core, too.
