How Do Specific Chemicals Affect Wetsuit Degradation & Longevity?
Quadri Abdur June 11th, 2025 Posted In: Articles
Wetsuits are essential gear for surfers, divers, kayakers, and swimmers. They provide warmth and protection in cold water. However, not all wetsuits last forever, and certain chemicals can speed up their wear and tear. How do chemicals affect wetsuits? Whether you’re an avid water sports enthusiast or a casual beachgoer, understanding how chemicals affect wetsuits can help extend their lifespan and save you money.
In this article, we’ll explore the different chemicals that can lead to wetsuit degradation, how they impact materials over time, and practical tips/insights for chemicals and wetsuit longevity.
What Causes Wetsuit Degradation?
Wetsuits are primarily made of neoprene fabric, a synthetic rubber that provides insulation and flexibility. While neoprene is highly durable, certain chemicals can weaken its structure. Thus, making the wetsuit lose elasticity, become brittle, or even start peeling. Some of the most common causes of wetsuit degradation include:
- Exposure to harsh chemicals like chlorine, salt, and sunscreen
- Improper cleaning techniques (quick tip: here’s how to properly clean a wetsuit)
- Long-term storage in humid or sunny conditions
- Frequent use without proper maintenance
By avoiding harmful substances and caring for your wetsuit correctly, you can ensure it stays in top shape for many seasons!
Chemicals and Wetsuit Degradation
Certain chemicals can negatively impact your wetsuit’s neoprene structure, thereby causing it to weaken, harden, or degrade faster than normal. Below are some of them:
Chlorine and Wetsuit Damage
Chlorine is commonly found in swimming pools and water treatment facilities. While it helps keep water clean, it can be rough on wetsuits.
- Effect on neoprene: Chlorine gradually breaks down neoprene. It makes it stiffer and more brittle over time.
- Visible signs: Wetsuits exposed to chlorinated water may lose flexibility and develop cracks.
- Prevention tip: Always rinse your wetsuit with fresh water after swimming in pools.
Saltwater and Its Long-Term Effects
Many wetsuit users spend time in the ocean, but saltwater can also be a silent destroyer.
- Effect on neoprene: Salt crystals can accumulate in the material and cause stiffness and abrasion.
- Visible signs: Over time, salt exposure can cause peeling or faded patches on a wetsuit.
- Prevention tip: Rinse your wetsuit thoroughly with fresh water after each ocean dive or surf session.
Sunscreen and Wetsuit Longevity
Sunscreen is vital for skin protection, but certain formulas can harm wetsuits.
- Effect on neoprene: Oils and chemicals in sunscreen can degrade neoprene and weaken its elasticity.
- Visible signs: Greasy spots or faded color in areas frequently exposed to sunscreen.
- Prevention tip: Apply sunscreen before putting on your wetsuit. You can also opt for reef-safe, neoprene-friendly formulas.
Laundry Detergents & Harsh Soaps
Cleaning a wetsuit is necessary, but using strong detergents or soaps can do more harm than good.
- Effect on neoprene: Harsh soaps strip away protective coatings and dry out neoprene, leading to cracking.
- Visible signs: Wetsuits washed with strong detergents may feel rough or stiff.
- Prevention tip: Use mild wetsuit cleaners or natural soaps to clean your gear.
Petroleum-Based Products
Many oils and lotions contain petroleum-based ingredients, which can quickly break down wetsuit material.
- Effect on neoprene: Direct contact with petroleum products can dissolve the neoprene surface.
- Visible signs: Sticky or peeling neoprene texture.
- Prevention tip: Avoid wearing lotions with petroleum ingredients before putting on your wetsuit.
How Chemicals Affect Wetsuit Longevity
To ensure wetsuit longevity, it’s essential to reduce exposure to harmful chemicals and practice good maintenance habits. Here’s how chemical exposure impacts wetsuit durability over time:
Loss of Flexibility
Neoprene naturally stretches to fit snugly, but repeated exposure to chemicals like chlorine and detergents can make it stiff. A rigid wetsuit not only feels uncomfortable but can also limit movement, reducing overall performance in the water.
Cracking and Peeling
When neoprene weakens due to chemical damage, it can develop cracks or peeling edges. This is a common issue for wetsuits frequently exposed to saltwater without proper cleaning.
Discoloration and Fading
Sunscreen, pool chemicals, and harsh detergents can strip away neoprene’s vibrant colors. Thus, making wetsuits appear dull or faded.
Reduced Thermal Insulation
A damaged wetsuit loses its ability to trap warmth effectively, making it harder to stay comfortable in cold water.
How to Maintain Your Wetsuit & Prevent Chemical Damage
The good news is that proper care can significantly extend your wetsuit’s lifespan. Here are some maintenance tips to keep your wetsuit in great shape:
- Always rinse your wetsuit with fresh, cool water after using it in chlorinated pools or saltwater environments. This helps remove lingering chemicals and prevents build-up.
- Instead of harsh detergents, use mild wetsuit shampoo or a natural soap to clean your gear.
- Avoid direct exposure to the sun and heat. Dry your wetsuit in a shaded area, as direct sunlight can weaken neoprene.
- Store in a cool, dry place. Avoid leaving your wetsuit in a humid or hot area, as this can lead to material degradation.
- Before applying sunscreen or lotions, check the ingredients to ensure they don’t contain petroleum or harsh chemicals.
- Lastly, if your wetsuit develops small cracks or peeling edges, use wetsuit repair glue to fix them before the damage worsens.
Conclusion
In conclusion, knowing how chemicals affect wetsuits is crucial for maintaining their quality and performance. Whether it’s chlorine from pools, saltwater from the ocean, or sunscreen ingredients, these substances can weaken neoprene and shorten a wetsuit’s lifespan. However, with proper care, including rinsing after use, storing correctly, and avoiding harsh products, you can ensure your wetsuit remains durable and functional for years.
By following these maintenance tips, you’ll extend your wetsuit’s longevity and also enjoy better performance and comfort every time you hit the water.
