Once you’ve found the perfect swimsuit, the key to preserving the swimsuit fabric is properly caring for, washing, and storing your bikini.

Now, while tossing your bathing suit in the washing machine might seem like the easiest option, it’s not always the best choice for maintaining the quality of your swimsuit fabric. The delicate elasticity of swimwear fabric can be easily damaged by machine agitation, harsh detergents, or high temperatures.

However, there are ways to machine wash your swimsuit or designer swimwear safely when absolutely necessary. In this guide, we’ll cover everything from the best hand-washing methods to proper machine washing techniques and drying techniques to make sure all your swimwear pieces, from  one-piece swimsuits to  triangle bikinis , last for years to come!

If you’re short on time, it’s tempting to toss your bikini or one-piece into the laundry with the rest of your clothes. But machine washing should always be done with caution. Swimwear fabrics like Lycra and spandex are delicate, and excessive agitation, hot water, or harsh detergent can lead to fading, stretching, and damage to the elastic fibers.

 Risks of machine washing a swimsuit: 

• Stretching and warping the fit of the suit

• Loss of elasticity due to hot water or rough spin cycles

• Faded colors from detergent and friction

• Trapped chlorine or saltwater that damages fabric over time

While machine washing isn’t ideal, there is a way to do it safely. If it’s your only option, follow the best practices below.

At ViX Paula Hermanny, we do not recommend washing your swimsuit in a washing machine, as it can damage the delicate fabrics and handcrafted details. To preserve the quality and longevity of your ViX swimwear, hand washing is always the safest option. If you're in a pinch and absolutely must use a machine for other swimwear (not ViX), here are some general precautions to take:

• Place the swimsuit in a mesh or lingerie bag for extra protection.
• Use a gentle or delicate cycle with cold water only.
• Choose a mild detergent made for delicates or swimwear—never use fabric softener.
• Avoid heavy items like jeans or towels in the same load to reduce friction.
• Skip the spin cycle if possible to help maintain shape.

Always check the care tag on your ViX swimsuit for specific washing instructions. Each piece is thoughtfully designed and may require slightly different care.

Handwashing is still the gentlest way to clean your swimsuit and preserve its vibrant colors and elasticity. Here’s how:

1. Prepare the Basin - Fill a sink or basin with cool water or lukewarm water.

2. Add a Small Amount of Gentle Detergent -Use a mild detergent, like one designed for delicate fabrics. If you don’t have detergent, a small amount of white vinegar can work as a natural cleanser.

3. Soak and Gently Swish -Let the swimsuit soak for 20–30 minutes, then gently swish it in the water to loosen dirt, oils, and chlorine. Avoid scrubbing or wringing.

4. Rinse Thoroughly -Rinse the bathing suit in fresh water until all detergent is removed.

5. Remove Excess Water -Lay the swimsuit on a clean towel and roll it gently to press out water.

Natural Bonus:  Add a pinch of baking soda to the soak to neutralize chlorine and deodorize.

It’s essential to wash your swimsuit after every wear, even if you didn’t swim. Sweat, sunscreen, and body oils can build up on the fabric, breaking down the fibers over time. Here are some best practices to follow:

• After pool swims - Rinse swimsuit immediately to remove chlorine. Chlorine can linger in the fibers, causing fading and weakening the elasticity of the fabric.

• After the beach - Rinse and clean to remove saltwater and sand.

• After sunbathing - Sunscreen and sweat can stain and break down the material—wash even if you didn’t swim.

Quick Care Tip: If you’re short on time, a quick rinse in cold water after every use can help minimize damage until you have the opportunity to handwash your suit.

Do's for washing

• Hand wash with a gentle detergent to avoid harsh chemicals.

• Rinse in clean water (preferably cool water) to maintain fabric quality.

• Don’t use hot water. Heat damages delicate fabrics.

• If machine washing, select the delicate cycle.

Do’s for Drying

• Lay flat to dry - Spread the swimsuit on a towel and let it air dry. This prevents stretching and fabric damage, so it remains elastic.

• Avoid direct sunlight - UV rays can fade colors and weaken fibers.

• Don’t wring or twist - This can stretch the material.

• Skip the dryer - The high heat can ruin the elasticity.

Quick Travel Tip: Roll your swimsuit in a towel to quickly remove water when you’re on the go.

Additional Tips for Preserving Color and Shape

• Rinse Before Swimming - Wet the swimsuit with fresh water before entering the pool to reduce chlorine absorption.

• Dedicated Hot Tub Suit - High temperatures can break down fibers faster — use an older suit for the jacuzzi.

• Proper Storage - Store flat in a cool, dry place to avoid creasing and maintain elasticity.

Common Mistakes to Avoid

• Using the Wrong Detergent - Strong laundry detergents can cause fading and damage. Stick to mild detergent or products designed for swimwear care.

• Soaking Overnight - Prolonged soaking weakens the fabric. Keep soak times under 30 minutes.

• Skipping the Rinse - Always rinse off salt water or chlorinated water immediately after swimming to prevent buildup.
