How to Care for Kids' Swimwear: Chlorine, Saltwater, and Sunscreen Stains

Summer days by the pool or at the beach are filled with splashing, swimming, and sunshine—but they can also take a toll on your child's favorite swimwear. Chlorine, saltwater, and sunscreen can cause colors to fade, fabrics to stretch, and odors to linger. With the right care routine, you can keep swimsuits looking vibrant and feeling comfortable all season long.

Whether you're dealing with a chlorine smell that won't quit or stubborn sunscreen stains, this guide covers everything you need to know about caring for kids' swimwear. From rinsing techniques to washing and drying best practices, we'll help you extend the life of those adorable suits—like the Ruffle Two-Piece Swim Set—so they're ready for every adventure.

Why Proper Swimwear Care Matters

Swimwear is made from delicate fabrics like spandex, nylon, and polyester, which are designed to stretch and move with your child. However, these materials are vulnerable to damage from chlorine, salt, and UV rays. Chlorine can break down elastic fibers, causing suits to lose their shape and become baggy. Saltwater can leave behind crystals that irritate skin and degrade fabric over time.

Sunscreen, while essential for protecting your child's skin, contains oils and chemicals that can stain and discolor swimwear. If not removed promptly, these stains can become permanent. By understanding the unique challenges each element presents, you can take proactive steps to keep swimwear in top condition.

• Chlorine weakens elastic and fades colors.
• Saltwater leaves residue that can damage fibers.
• Sunscreen oils can cause yellowing and stains.

Immediate After-Swim Care: Rinse and Soak

The most important step in swimwear care is rinsing immediately after your child gets out of the water. Rinse the suit in cold, fresh water to remove chlorine, salt, and sunscreen before they have a chance to set. A quick rinse in the shower or a bucket of water can make a huge difference.

For a deeper clean, soak the swimsuit in a mixture of cold water and a gentle detergent or a specialized swimwear cleaner for 15-30 minutes. This helps break down chemical residues and removes odors. Avoid hot water, as it can set stains and damage elastic fibers.

• Rinse in cold water right after swimming.
• Soak in a gentle detergent solution for 15-30 minutes.
• Never use hot water for swimwear.

How to Wash Kids' Swimwear: Hand vs. Machine

Hand washing is the gentlest method and is always recommended for swimwear. Fill a basin with cold water and add a small amount of mild detergent. Gently squeeze the suit, paying attention to areas with sunscreen or stains. Rinse thoroughly until the water runs clear.

If you prefer machine washing, use a mesh laundry bag to protect the suit from snagging. Select a delicate cycle with cold water and a mild detergent. Avoid fabric softeners, as they can coat the fabric and reduce its water-repellent properties. Always check the care label on your child's swimwear for specific instructions.

For added protection, turn the swimsuit inside out before washing to minimize friction and preserve the outer color and print.

• Hand wash is best; use a gentle detergent.
• Machine wash in a mesh bag on delicate cycle.
• Skip fabric softeners and turn suits inside out.

Removing Chlorine Smell and Sunscreen Stains

Chlorine smell can be stubborn, but a simple vinegar solution can neutralize it. Mix one part white vinegar with three parts cold water and soak the swimsuit for 30 minutes. Rinse thoroughly afterward. Alternatively, baking soda can help—add a tablespoon to the soaking water.

For sunscreen stains, apply a small amount of gentle stain remover or dish soap directly to the affected area and gently rub before washing. Avoid using bleach or harsh chemicals, as they can damage the fabric. For persistent stains, repeat the treatment or consider a specialized swimwear cleaner.

Always test any stain remover on a small, inconspicuous area first to ensure it doesn't affect the color.

• Vinegar solution removes chlorine odor.
• Dish soap or stain remover tackles sunscreen stains.
• Test any treatment on a hidden area first.

Drying and Storing Swimwear: Do's and Don'ts

Proper drying is crucial to maintain the shape and elasticity of swimwear. Never wring out the suit, as this can stretch and damage the fabric. Instead, gently press out excess water with a towel by laying the suit flat on a clean towel and rolling it up.

Air dry the swimsuit flat in a shaded area. Avoid direct sunlight, which can fade colors, and never use a dryer, as heat can break down elastic fibers. Once dry, store swimwear in a cool, dry place. Avoid folding it in tight spaces that can cause creases; laying it flat or hanging it loosely is better.

If you have multiple swimsuits, consider rotating them to allow each one to fully dry and recover its shape between uses.

• Press water out with a towel; never wring.
• Air dry flat in shade; avoid direct sun and dryers.
• Store flat or loosely hung in a cool, dry place.

Special Care for Swimwear Accessories and Mix-and-Match Pieces

Many kids' swimwear sets include coordinating pieces like swim shirts, rash guards, and swim shorts. These items often have similar care requirements, but always check the label. For example, the Ruffle Two-Piece Swim Set features delicate ruffles that benefit from hand washing to maintain their shape.

If your child wears a swim hat or cover-up, follow the same rinsing and air-drying principles. Accessories like the Baby Hat Two-Pack can be gently hand washed and laid flat to dry to prevent misshaping.

By giving each piece the same attention, you'll keep the entire outfit looking cohesive and ready for the next pool day.

• Check care labels on all swim pieces.
• Hand wash delicate details like ruffles.
• Treat accessories with the same gentle care.

Caring for kids' swimwear doesn't have to be complicated. By rinsing promptly, washing gently, and drying properly, you can protect your child's favorite suits from chlorine, saltwater, and sunscreen damage.
