AvatarByColleen Barnes Shower Routine & Lifestyle

There’s nothing quite like slipping into a fresh, vibrant bathing suit to kick off a day by the pool or at the beach. But after all the sun, saltwater, and chlorine, your favorite swimwear needs more than just a quick rinse to stay looking its best. Knowing how to properly clean a bathing suit is essential not only for maintaining its color and shape but also for extending its lifespan.

Caring for swimwear involves more than just tossing it in the washing machine or letting it air dry. The delicate fabrics and elastic fibers require special attention to prevent damage and fading. Understanding the right cleaning techniques can help you preserve the fit, comfort, and appearance of your bathing suit, ensuring it remains a staple in your summer wardrobe for seasons to come.

In the following sections, we’ll explore the best practices for cleaning your bathing suit, from gentle hand-washing methods to tips on drying and storage. Whether you’re a casual beachgoer or a dedicated swimmer, mastering these care routines will keep your swimwear fresh, vibrant, and ready for every splash.

Proper Washing Techniques for Bathing Suits

After rinsing your bathing suit thoroughly in cold water, the next step is to wash it carefully to preserve its elasticity and color. Hand washing is highly recommended over machine washing, which can be harsh and cause damage. Use a gentle detergent specifically formulated for delicate fabrics or swimwear. Avoid bleach or fabric softeners, as these can degrade the fibers and fade the colors.

To hand wash your bathing suit:

  • Fill a basin with cool or lukewarm water.
  • Add a small amount of mild detergent and mix until dissolved.
  • Submerge the bathing suit, gently agitating it for a few minutes.
  • Pay special attention to areas with sunscreen or sweat buildup but avoid scrubbing aggressively.
  • Rinse thoroughly in cold water until all detergent is removed.

If you must use a washing machine, place the bathing suit in a mesh laundry bag and select the delicate cycle with cold water only. However, this method is less ideal and should be reserved for suits that are more durable.

Drying Your Bathing Suit Correctly

Drying your bathing suit properly is as crucial as washing it. Excessive heat or direct sunlight can cause fading, fiber breakdown, and loss of stretch. Avoid using a dryer or wringing the fabric, as this can distort the shape.

Follow these steps for drying:

  • Gently squeeze out excess water without twisting or wringing.
  • Lay the suit flat on a clean, dry towel.
  • Roll the towel with the suit inside to remove additional moisture.
  • Unroll and lay the bathing suit flat on a dry towel in a shaded, well-ventilated area.
  • Allow it to air dry completely before storing.

Avoid hanging suits by the straps, as this can cause stretching and deformation over time.

Special Care Tips for Different Fabric Types

Bathing suits are made from various fabric blends, each requiring slightly different care considerations. Here’s a quick guide:

Fabric Type Recommended Care Precautions
Nylon/Spandex (Lycra) Hand wash in cool water, mild detergent, air dry flat Avoid hot water and bleach; do not machine dry
Polyester/Spandex Gentle hand wash or delicate machine cycle; air dry Avoid fabric softeners; avoid high heat
Neoprene (Wetsuits) Rinse with fresh water after use; hand wash with wetsuit shampoo Do not wring or twist; air dry away from direct sun
Chlorine-Resistant Fabrics Rinse immediately after use; hand wash gently Avoid long soaking; avoid bleach and high heat drying

By tailoring your care routine to the fabric composition, you can extend the life and maintain the appearance of your bathing suit.

Dealing With Stains and Odors

Sunscreen, oils, chlorine, and sweat can leave stains and unpleasant odors if not treated promptly. For best results:

  • Treat stains immediately by gently rubbing a mixture of water and mild detergent or a specialized stain remover on the affected area.
  • For odors, soak the suit in a solution of cold water and white vinegar (about 1 cup per gallon) for 15-30 minutes before washing.
  • Avoid harsh chemicals or bleach, as these can damage the fabric.
  • Allow the bathing suit to dry completely after treatment to prevent mildew.

Regular maintenance with proper rinsing and washing after every use helps reduce buildup and keeps your bathing suit fresh.

Proper Techniques for Washing a Bathing Suit

Maintaining the integrity and appearance of a bathing suit requires careful washing techniques. The delicate fabrics and elastic components demand gentle handling to prevent damage and preserve color vibrancy.

Follow these expert steps to effectively clean your bathing suit:

  • Rinse Immediately After Use: After swimming, rinse your suit thoroughly with cool, fresh water. This step removes chlorine, salt, sand, and other residues that can degrade fabric fibers.
  • Hand Wash Only: Machine washing can be too abrasive. Fill a basin with cool water and add a small amount of mild detergent designed for delicate fabrics.
  • Gentle Agitation: Submerge the suit and gently swirl it for a few minutes. Avoid scrubbing or twisting, which can stretch and damage the fabric.
  • Rinse Thoroughly: Remove all detergent by rinsing the suit multiple times with cool water until no suds remain.
  • Do Not Wring: Instead, press the suit gently between two towels to remove excess water without stretching the fibers.

These steps ensure effective cleaning while maintaining the swimsuit’s elasticity and color.

Detergent Selection and Avoiding Common Mistakes

Choosing the right cleaning agent is crucial for bathing suit care. Harsh detergents can cause fading, fabric breakdown, or loss of stretch.

Detergent Type Pros Cons Recommendation
Mild Liquid Detergent Gentle on fabrics; dissolves easily in cold water May contain enzymes that degrade elastane if not specifically designed for delicate fabrics Use detergents labeled for delicate or lingerie washing
Specialty Swimsuit Cleaner Formulated to remove chlorine and salt; preserves elasticity More expensive; less widely available Ideal for frequent swimmers or high-end suits
Powder Detergent Effective for heavy stains May not dissolve completely in cold water; abrasive particles Avoid for bathing suits
  • Avoid bleach and fabric softeners: These can break down fibers and reduce elasticity.
  • Do not use hot water: High temperatures can cause fading and fabric damage.
  • Skip the dryer: Air drying flat away from direct sunlight is preferred to prevent shrinking and color loss.

Best Practices for Drying and Storing Bathing Suits

Proper drying and storage extend the life of your bathing suit by preventing deformation and fabric deterioration.

Implement the following guidelines for drying and storing:

  • Dry Flat: Lay the suit flat on a clean, dry towel, reshaping it to its original form. Avoid hanging, which can stretch the fabric over time.
  • Avoid Direct Sunlight: Prolonged exposure to UV rays causes fading and fiber breakdown. Dry in a shaded, well-ventilated area.
  • Ensure Complete Dryness: Before storing, confirm the suit is fully dry to prevent mildew and odor.
  • Store Properly: Place the suit in a breathable fabric bag or drawer. Avoid plastic bags that trap moisture.

By adhering to these drying and storage recommendations, you preserve both the look and functional qualities of your bathing suit.
