How To Wash A Swimming Costume And Make It Last Longer

Darren Diong

If you swim often, you already know how quickly swimwear can lose its shape or colour. Chlorine, salt, sweat, and even sunscreen can wear down the fabric fast. But the truth is, your swimsuit doesn’t have to fade or stretch after just a few uses. With the right care, you can make it last much longer. It all starts with how you wash and handle it.

Whether you swim for fun, training, or recovery, your costume goes through a lot each time you hit the pool. The fibres stretch, absorb chemicals, and face heat and sunlight. Learning how to wash it properly keeps it fresh, clean, and comfortable. 

Here’s how to do it the right way.

Why You Should Wash Your Costume Properly

A swimming costume is made from soft, stretchy fabric that wears out fast if not cleaned properly. Chlorine, salt, and sunscreen can all damage it over time. Washing it properly helps protect the fibres and keep it looking new.

Here’s why it matters:

  • Removes chlorine and salt: These chemicals break down elastic fibres and fade colours fast.
  • Prevents odour buildup: Sweat and sunscreen left behind can cause unpleasant smells.
  • Keeps shape and stretch: Gentle washing helps the suit stay firm and snug longer.
  • Maintains colour: Regular rinsing keeps bright shades from turning dull.
  • Saves money: Taking care of one good costume is cheaper than replacing it often.

Rinse Right After Swimming

The best time to clean your swimsuit is right after you get out of the water. Rinse it in cool, clean water for a minute or two. This helps remove most of the chlorine or salt before it sinks into the fabric.

If you can, rinse it right at the pool shower area. Swimmers are often reminded to shower before and after swimming, not just for hygiene but also to protect the pool and their skin. Rinsing your suit right away does the same thing. It’s a simple step that goes a long way.

Hand Wash It Gently

Machines are too rough for swimsuits. The spinning and strong detergents can stretch out the fibres. Always hand-wash your costume. Fill a small basin with cool or lukewarm water, then add a bit of mild soap.

You don’t need fancy detergent. A gentle baby shampoo or a special swimwear wash works well. Let the swimsuit soak for about ten minutes. Swish it around gently to remove dirt or lotion residue. Then rinse it again in clean water until there are no suds left.

Avoid twisting or scrubbing hard. Just squeeze lightly to remove excess water.

Avoid Hot Water and Harsh Cleaners

Hot water can cause the fabric to lose its elasticity faster. Always stick to cold or lukewarm water. Never use bleach or fabric softeners. These chemicals might make your swimsuit smell clean at first, but they eat away at the fibres.

If your costume smells strongly of chlorine, mix a bit of white vinegar in cool water and soak it for a few minutes. This neutralises the odour without damaging the fabric.

Dry It the Right Way

Drying is where many people make mistakes. Never wring out your swimsuit. It can stretch and ruin the elastic. Instead, press it gently between your hands to remove excess water.

Lay it flat on a towel and roll it up to absorb moisture. Then place it flat in a shaded area to air dry. Avoid hanging it by the straps or leaving it in direct sunlight. The heat can fade colours and weaken the fabric faster.

Avoid using a dryer. Even on low heat, it can cause damage. Patience is key here. Let it dry naturally.

Storage Tips

Once dry, store your swimsuit flat or folded neatly. Avoid crumpling it in a gym bag or keeping it damp inside a plastic pouch. That’s how bacteria and odours build up.

If you swim often, consider having more than one costume. Rotating between two or three gives each one time to dry and rest. This helps them last longer and keeps them from overstretching.

Extra Tips to Make It Last Longer

Here are a few more small habits that make a big difference:

  • Rinse off before you get into the pool. It removes body oils and sweat, which helps your swimsuit resist chlorine.
  • Avoid sitting on rough surfaces like concrete edges. They can snag or tear the fabric.
  • Take off your suit as soon as you’re done swimming. Letting it dry on your body can stretch it.
  • Don’t iron it. The heat ruins elastic fibres.
  • Keep a bag with swimming essentials you need, like a towel, spare swimsuit, mild soap, and water bottle, to make post-swim care easier.

Care for Your Other Swim Gear Too

Care for Your Other Swim Gear Too

Your swimsuit isn’t the only thing that needs care. Goggles, caps, and towels also wear down over time. For example, learning how to clean swimming goggles helps keep your vision clear and the straps in good condition. Just rinse them with fresh water and let them air dry after every swim.

Taking a few minutes to care for your gear saves you money and keeps your swimming experience smooth.

Build a Good Routine

The more consistent you are, the better your swimsuit will last. Make washing part of your post-swim routine. Rinse, hand-wash, and dry it properly. It doesn’t take long and keeps your costume looking new for months.

If you’re into swim training or learning new techniques like the combat side stroke, your swimsuit is part of your performance. A clean, flexible, and well-fitting costume makes every movement easier and more comfortable.
