Is it Safe to Wash Your Swimwear in a Washing Machine?


The Risks of Machine Washing


Machine washing is often too harsh for delicate fabrics like Lycra and spandex, which are common in swimsuits. The intense agitation and spinning can:


  • Stretch the fabric, leading to sagging and loss of elasticity.

  • Cause color fading due to friction and exposure to harsh laundry detergents.

  • Trap leftover chemicals like chlorine bleach, salt water, or sunscreen, leading to discoloration.


How to Wash Swimwear in Washing Machine Safely


While handwashing is always the better choice when possible, machine washing can also be an alternative, especially if you don’t have the luxury of time. If you need to use the washing machine, follow these tips for washing a swimsuit to protect your favorite piece:


  1. Select the delicate cycle and use cold water or lukewarm water.

  2. Choose a mild detergent or one specifically formulated for swimwear care.

  3. Avoid fabric softeners as they can weaken the fibers.

How to Properly Handwash Your Swimsuit

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 Gentle Cleaner -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.


Pro Tip:You can add a pinch of baking soda to the soak to help neutralize chlorinated water and deodorize the fabric.

How Often Should You Wash Your Swimsuit?

Wash Your Swimsuit After Every Wear

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. If you’ve been swimming in a chlorinated pool, it’s even more critical to rinse your swimsuit right away. Chlorine can linger in the fibers, causing fading and weakening the elasticity of the fabric.

For those who regularly visit the ocean, salt water can also leave behind residue that needs to be rinsed off with fresh water as soon as possible. Sunscreen and tanning oils are also particularly harsh on swimwear fabric, so be sure to give your swimsuit a thorough wash to prevent stains and material breakdown.

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. Regular care goes a long way in preserving your swimsuit’s fit and vibrant colors.

Best Practices for Washing and Drying Your Swimsuit


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.

  • 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’ts


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

  • 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


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

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

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