How to Remove Mold from Wetsuit

Mold on your wetsuit isn't just ugly, it's a sign your suit isn't drying properly. Wetsuits are made from neoprene, a material that traps moisture even after you rinse them. When that moisture sits in a dark, warm spot, mold spores move in and set up shop. The good news: removing mold from a wetsuit is straightforward, and preventing it is even easier. Whether you're dealing with black spots, a musty smell, or visible discoloration, we'll walk you through exactly what to do. Regular maintenance and proper storage keep your mold-free wetsuit lasting longer and feeling better against your skin.

If your wetsuit has stubborn mold that vinegar doesn't fully eliminate, you have a few stronger options. Baking soda paste works well for surface mold: mix baking soda with a little water to form a paste, apply it to affected areas, let it sit for 15 minutes, then rinse thoroughly. For deeper mold inside the suit, soak it in a solution of one tablespoon of baking soda per gallon of fresh water for an hour. Another effective method is using a diluted bleach solution, but this should be a last resort since bleach can weaken neoprene over time. If you go this route, use one part bleach to ten parts water, soak for 10 minutes only, then rinse multiple times. Always air dry completely afterward. The key is addressing mold early before it spreads through the suit's interior. Once your wetsuit is mold-free, focus on prevention through quick rinses and proper drying. Consider using a wetsuit hanger or drying rack to speed up the drying process and keep your suit in top shape.

Can I use regular detergent to clean mold from my wetsuit?

Regular laundry detergent isn't ideal for removing mold from wetsuits. Detergent is designed to lift oils and dirt, not kill mold spores. Stick with white vinegar, baking soda, or specialized wetsuit cleaners instead. If you do use detergent, rinse extremely well to avoid residue that traps moisture and encourages mold to return.

How often should I clean my wetsuit to prevent mold?

Rinse your wetsuit with fresh water after every use, ideally within an hour. This is the most important step for mold prevention. Do a deeper vinegar soak once a month if you're using your suit regularly, or whenever you notice a musty smell. Proper drying between uses prevents most mold problems from starting.

Is mold on a wetsuit dangerous?

Mold on your wetsuit can irritate your skin and cause itching or rashes, especially if you have sensitive skin or open cuts. Inhaling mold spores while putting on a moldy suit may trigger respiratory issues. Beyond health concerns, mold breaks down neoprene fibers over time, shortening your suit's lifespan. Removing it promptly protects both you and your gear.

What's the best way to dry a wetsuit to prevent mold?

Hang your wetsuit on a padded hanger in a well-ventilated area away from direct sunlight and heat sources. Make sure air can flow through the suit, not just around it. Drying typically takes 24 to 48 hours depending on humidity and temperature. Never leave it bunched up, in a bag, or in a damp basement. A dedicated wetsuit rack or hanger speeds up the process and keeps mold at bay.

Can I machine wash my wetsuit to remove mold?

Machine washing is too harsh for wetsuits and can damage the neoprene, glue seams, and zippers. Stick to hand washing with vinegar or baking soda solutions instead. These methods are gentler on your suit while still effectively killing mold spores. Hand washing also lets you target specific moldy areas without over-cleaning the entire suit.

What should I do if mold keeps coming back?

Recurring mold means your drying or storage method isn't working. Check that your suit is fully dry before storing it, ensure your storage area has good air circulation, and avoid plastic bags or sealed containers. If humidity is high where you live, consider using a small dehumidifier in your storage space. Also make sure you're rinsing immediately after use to remove salt and chlorine that feed mold growth.
