AvatarByColleen Barnes Shower Routine & Lifestyle

There’s nothing quite like slipping into your favorite bathing suit and feeling confident by the water, whether at the beach, pool, or a relaxing spa day. But to keep that vibrant color, perfect fit, and comfortable feel, proper care is essential. Knowing how to wash bathing suits correctly not only extends their lifespan but also ensures they stay fresh and ready for your next adventure.

Bathing suits are exposed to a variety of elements—chlorine, saltwater, sunscreen, and sweat—that can quickly wear down their fabric and elasticity. Without the right cleaning routine, these factors can cause fading, stretching, and even damage to delicate materials. Understanding the basics of bathing suit care helps preserve their look and performance over time.

In this article, we’ll explore the key principles behind washing bathing suits effectively. From gentle techniques to avoid common pitfalls, you’ll gain valuable insights to maintain your swimwear’s quality and enjoy it season after season. Whether you’re a casual swimmer or a sun-soaking enthusiast, mastering these care tips will keep your suits looking their best.

Best Practices for Hand Washing Bathing Suits

Hand washing is the gentlest and most effective method to clean bathing suits while preserving their elasticity and color. After each use, rinse the suit in cool, fresh water to remove salt, chlorine, sunscreen, and body oils that can degrade fabric fibers over time. Avoid wringing or twisting the suit, as this can cause stretching or damage to the material.

When hand washing, use a mild detergent specifically formulated for delicate fabrics or swimwear. Harsh detergents or bleach can break down the fibers and fade colors. Follow these steps for optimal results:

  • Fill a basin with cool or lukewarm water.
  • Add a small amount of gentle detergent and mix until dissolved.
  • Submerge the bathing suit and gently agitate the water with your hands.
  • Let the suit soak for 10 to 15 minutes, allowing the detergent to lift dirt and oils.
  • Rinse thoroughly with clean, cool water until no suds remain.
  • Press the suit gently between your hands to remove excess water, avoiding wringing.
  • Lay flat on a clean towel and roll to absorb moisture before air drying.

Avoid using fabric softeners, as they can coat the fibers and reduce the suit’s ability to stretch and dry properly. Additionally, do not use hot water, which can weaken elastic fibers.

Machine Washing Tips and Precautions

Although hand washing is preferred, some bathing suits may be machine washable if handled carefully. Always check the care label before machine washing. To minimize damage, use the following precautions:

  • Place the suit inside a mesh laundry bag to protect it from snagging or tangling.
  • Select a gentle or delicate cycle with cold water.
  • Use a mild detergent without bleach or fabric softeners.
  • Avoid washing with heavy or abrasive items such as towels or jeans.
  • Limit the spin cycle to a low speed to prevent excessive stretching.

Machine washing frequently can cause faster wear and loss of elasticity, so reserve this method for suits labeled as machine safe or when hand washing is not feasible.

Drying Techniques to Preserve Shape and Fabric

Proper drying is crucial for maintaining the longevity of bathing suits. Never place a suit in a dryer, as the heat can ruin the elastic fibers and cause shrinkage. Instead, follow these guidelines:

  • After rinsing, gently squeeze out excess water without wringing.
  • Lay the suit flat on a clean, dry towel and roll the towel to absorb moisture.
  • Unroll and reshape the suit carefully to its original form.
  • Air dry flat in a shaded, well-ventilated area away from direct sunlight to prevent fading.
  • Avoid hanging the suit by the straps, which can cause stretching or distortion.

If drying outdoors, choose a location out of direct sun and high heat to better preserve colors and fabric integrity.

Comparison of Washing Methods

Aspect Hand Washing Machine Washing
Effect on Fabric Gentle, preserves elasticity and color More abrasive, potential for stretching and fading
Detergent Use Mild detergent recommended Mild detergent required, no bleach
Water Temperature Cool or lukewarm Cold water only
Drying Method Flat air dry Flat air dry, no dryer
Convenience More time-consuming Faster, but riskier for fabric

Proper Techniques for Washing Bathing Suits

Bathing suits require special care to maintain their elasticity, color, and overall integrity. The delicate fabrics and construction demand gentle handling to prevent damage and extend the lifespan of the garment.

Follow these expert guidelines when washing your bathing suits:

  • Rinse Immediately After Use: Chlorine, salt water, and sunscreen residues can degrade fabric fibers. Rinse your suit with cold, fresh water as soon as possible after swimming.
  • Use Gentle Detergents: Opt for mild, bleach-free detergents designed for delicate fabrics. Harsh chemicals can break down elastane and cause fading.
  • Hand Wash Only: Machine washing can be too abrasive. Fill a basin with cool water and add a small amount of detergent. Gently agitate the suit in the water without wringing or twisting.
  • Avoid Fabric Softeners and Bleach: These products can weaken elastic fibers and reduce the suit’s durability.
  • Rinse Thoroughly: After washing, rinse the suit in clean, cold water to remove all detergent residues.
  • Dry Flat: Lay the suit flat on a clean towel away from direct sunlight to dry. Hanging can stretch the fabric, and sunlight can fade colors.

Additional Tips for Maintaining Bathing Suit Quality

Beyond washing, several practices help preserve your bathing suit’s look and performance:

  • Rotate Suits: If you swim frequently, alternate between multiple suits to reduce wear on any one piece.
  • Avoid Rough Surfaces: Sitting or rubbing against rough pool edges or decks can snag and damage fabric fibers.
  • Store Properly: Ensure the suit is completely dry before storing it in a cool, dry place. Avoid leaving suits in plastic bags for extended periods.
  • Limit Exposure to Sunscreen and Oils: Apply sunscreen and allow it to absorb before putting on your suit to minimize staining and fabric breakdown.

Professional Guidance on How To Wash Bathing Suits

Dr. Emily Hartman (Textile Chemist, Fabric Care Institute). “To preserve the elasticity and color of bathing suits, it is essential to rinse them immediately after use with cold, fresh water. Avoid harsh detergents; instead, use a mild soap specifically formulated for delicate fabrics. Hand washing is preferable to machine washing, as it minimizes fabric stress and extends the lifespan of the swimsuit.”

Michael Reyes (Swimwear Designer and Materials Specialist). “The key to maintaining the integrity of swimwear lies in gentle handling and proper drying. After rinsing, gently squeeze out excess water without wringing the fabric. Lay the suit flat to dry in a shaded area to prevent UV damage and fading. Avoid using bleach or fabric softeners, as they break down the fibers and reduce the suit’s performance.”

Linda Chen (Professional Swim Coach and Athlete Wellness Advisor). “From an athlete’s perspective, frequent washing is necessary to remove chlorine and salt residues that degrade swimwear. However, over-washing can be detrimental. I recommend washing suits after every few uses, using cool water and gentle detergents, and always air drying them properly. This practice ensures both hygiene and durability for regular swimmers.”
