Whether you've invested in a supportive one piece or your favourite bikini, knowing how to properly care for your swimwear can dramatically extend its lifespan.
Sun, saltwater, chlorine, sunscreen and body oils all take a toll on swimwear fabrics over time. Fortunately, with just a few simple habits, you can help your bathers maintain their shape, colour and elasticity for many seasons to come.
If you've ever wondered how to wash swimwear properly or how to make your bathers last longer, this guide covers everything you need to know.
Why Swimwear Needs Special Care
Unlike everyday clothing, swimwear is made from highly technical stretch fabrics that are designed to provide support, shape and comfort while retaining their elasticity.
These fabrics are constantly exposed to:
- Chlorine
- Saltwater
- Sunscreen and tanning oils
- Perspiration
- Heat
- UV rays
- Rough pool edges and decking
Without proper care, these elements can gradually break down the fibres, causing your swimsuit to lose its stretch, fade or become misshapen.
Step 1: Rinse Your Swimwear Immediately After Every Wear
One of the simplest ways to make your swimwear last longer is to rinse it as soon as possible after wearing it.
Even if you haven't been swimming, sunscreen, sweat and body oils remain trapped in the fabric.
Use cool, fresh water to remove:
- Chlorine
- Salt
- Sand
- Sunscreen
- Body oils
Avoid leaving wet swimwear sitting in a beach bag or wrapped in a towel for extended periods, as this encourages bacteria growth and can damage delicate fibres.
Step 2: Hand Wash Gently
The best way to wash swimwear is always by hand.
Fill a basin with cool water and add a small amount of mild detergent or a detergent specifically designed for delicate fabrics.
Gently swish the swimsuit through the water before rinsing thoroughly.
Avoid:
- Harsh detergents
- Bleach
- Fabric softener
- Stain removers
These products can damage the elastic fibres that give swimwear its support.
Step 3: Never Wring or Twist
It can be tempting to squeeze excess water from your swimsuit, but twisting or wringing the fabric stretches the fibres and can permanently alter its shape.
Instead:
- Gently press the water out.
- Roll the swimsuit inside a clean towel to absorb excess moisture.
- Lay flat to dry.
This simple step helps preserve the fit and structure of your swimwear.
Step 4: Dry in the Shade
Direct sunlight may seem like the quickest drying method, but prolonged UV exposure can fade colours and weaken swimwear fibres.
Instead, always:
- Lay swimwear flat.
- Dry in the shade.
- Allow it to air dry naturally.
Avoid hanging wet swimwear by the straps, as the weight of the water can stretch the fabric.
Never use a clothes dryer, as excessive heat quickly damages elastic fibres.
Step 5: Store Your Swimwear Properly
Before putting your swimwear away, make sure it is completely dry.
Store it:
- Flat where possible
- In a cool, dry place
- Away from direct sunlight
Avoid leaving damp swimwear inside gym bags, beach bags or plastic bags.
Common Swimwear Care Mistakes
Even high-quality swimwear can wear out prematurely if it's not cared for correctly.
Try to avoid these common mistakes:
Machine Washing
The agitation of a washing machine can stretch and weaken delicate fibres.
Tumble Drying
Heat is one of the quickest ways to damage swimwear elasticity.
Sitting on Rough Surfaces
Concrete pool edges, rocks and timber decking can snag or abrade the fabric.
A simple beach towel provides an easy layer of protection.
Leaving Chlorine on the Fabric
Chlorine is designed to break down organic matter, so allowing it to remain in the fabric for hours can reduce the lifespan of your swimsuit.
Always rinse as soon as possible.
Frequently Asked Questions
Can you put swimwear in the washing machine?
Hand washing is always recommended.
How often should you wash swimwear?
Swimwear should be rinsed after every wear and ideally hand washed after each use to remove chlorine, saltwater, sunscreen and body oils.
Can you dry swimwear in the sun?
It's best to dry swimwear in the shade. Direct sunlight can fade colours and weaken the fibres over time.
Why shouldn't you wring out swimwear?
Wringing twists and stretches the elastic fibres, causing the swimsuit to lose its shape more quickly.
How long should a quality swimsuit last?
With proper care, a well-made swimsuit can maintain its fit and appearance for many seasons. The lifespan depends on how often it's worn and whether it's exposed to chlorine, saltwater and prolonged sun exposure.
