AvatarByKristie Pacheco Skincare

There’s nothing quite like a sunny day at the beach or pool, but along with the fun often comes an all-too-common frustration: sunscreen stains on your favorite bathing suit. Those stubborn marks can quickly turn your vibrant swimwear dull and dingy, leaving you wondering how to restore it to its original glory. If you’ve ever found yourself staring at a sunscreen-streaked swimsuit, you’re not alone—and there’s good news: effective solutions are within reach.

Sunscreen, while essential for protecting your skin, contains oils and chemicals that tend to cling stubbornly to fabric fibers. This can make removing it from delicate swimwear a tricky task, especially since bathing suits often feature materials that require gentle care. Understanding why sunscreen stains occur and how they interact with different fabrics is the first step toward tackling the problem effectively.

Before you toss your suit into the wash or give up on it altogether, it’s important to know the right approach to cleaning and treating sunscreen stains. With the right techniques, you can preserve the color, elasticity, and overall look of your bathing suit, ensuring it’s ready for your next sunny adventure. In the following sections, we’ll explore practical tips and tried-and-true methods to help you get sunscreen out of your bathing suit safely and efficiently.

Effective Pre-Treatment Techniques for Sunscreen Stains

Before washing the bathing suit, it is crucial to pre-treat the sunscreen stains to break down the oils and pigments effectively. Start by gently blotting the stained area with a clean cloth or paper towel to remove any excess sunscreen, taking care not to spread the stain further. Avoid rubbing, as this can embed the sunscreen deeper into the fabric fibers.

Next, apply a pre-treatment solution specifically designed for oily or greasy stains. Common options include:

  • A liquid dishwashing detergent that targets grease
  • A stain remover pen or spray formulated for oily substances
  • A mixture of baking soda and water applied as a paste

Work the chosen solution into the fabric using your fingers or a soft-bristled toothbrush, focusing on the stained areas. Let it sit for 10 to 15 minutes to allow the active ingredients to penetrate and break down the sunscreen components.

Washing Instructions to Remove Sunscreen from Bathing Suits

Proper washing techniques are essential to completely remove sunscreen residues without damaging the fabric. Follow these guidelines to clean your bathing suit effectively:

  • Use cold or lukewarm water to avoid setting the stain
  • Select a gentle detergent free of bleach or harsh chemicals
  • Hand wash the bathing suit or use a washing machine’s delicate cycle inside a mesh laundry bag
  • Avoid fabric softeners, as they can interfere with stain removal and damage elastic fibers

After washing, inspect the suit for any remaining stains before drying. If the stain persists, repeat the pre-treatment and washing steps. Do not put the suit in a dryer until the stain is fully removed, as heat can permanently set the sunscreen.

Home Remedies and Natural Solutions for Sunscreen Stains

If commercial stain removers are unavailable, certain household items can serve as effective alternatives to treat sunscreen stains:

  • White vinegar: Soak the stained area in a mixture of equal parts white vinegar and water for 15-30 minutes before washing.
  • Lemon juice: Apply lemon juice directly to the stain and allow it to sit for a few minutes; the natural acidity helps break down oils.
  • Baking soda paste: Mix baking soda with water to form a thick paste, apply to the stain, and let it sit before rinsing.
  • Rubbing alcohol: Dab a small amount onto the stain to dissolve oils, but test on a hidden area first to ensure colorfastness.

These natural remedies can be useful for delicate fabrics, but always rinse thoroughly and avoid prolonged exposure to prevent fabric damage.

Effective Methods to Remove Sunscreen Stains from Bathing Suits

Sunscreen stains on bathing suits are a common problem due to the oils and pigments in many formulas. These stains can be stubborn, but several targeted cleaning methods can effectively restore your suit’s original appearance without damaging the fabric.

Before attempting stain removal, always check the care label of your bathing suit to avoid using any cleaning agents or techniques that may degrade the material or its elasticity.

Immediate Steps to Take After Sunscreen Contact

  • Rinse with Cold Water: Rinse the affected area under cold running water as soon as possible to dilute and flush out excess sunscreen.
  • Avoid Hot Water: Hot water can set the stain and damage the fabric fibers, making removal more difficult.
  • Do Not Rub Vigorously: Gentle handling prevents fabric distortion and pilling.

  • Air dry flat in the shade to prevent fading and loss of elasticity.

Additional Tips to Prevent Sunscreen Stains

  • Allow sunscreen to fully absorb into your skin before putting on your bathing suit.
  • Choose sunscreens labeled as “non-greasy” or “quick-absorbing” to minimize residue.
  • Rinse your bathing suit immediately after swimming or sunbathing to remove any residual sunscreen.
  • Consider wearing a cover-up or rash guard to reduce direct sunscreen contact with swimwear fabric.

Professional Advice on Removing Sunscreen Stains from Bathing Suits

Dr. Emily Carter (Textile Chemist, Fabric Care Innovations). When dealing with sunscreen stains on bathing suits, it is crucial to treat the fabric promptly. I recommend rinsing the suit in cold water immediately to prevent the oils from setting. Following this, apply a gentle, enzyme-based stain remover specifically designed for synthetic fabrics, then wash on a delicate cycle with cold water. Avoid bleach or harsh detergents, as they can damage the swimsuit’s fibers and elasticity.

Michael Thompson (Professional Swimwear Designer, AquaWear Studios). Sunscreen stains often come from the oils and UV filters in the lotion, which bond strongly with the synthetic fibers in swimsuits. I advise soaking the suit in a mixture of white vinegar and water for 30 minutes before washing, as vinegar helps break down the oils without harming the fabric. Always air dry the bathing suit away from direct sunlight to maintain its color and shape after cleaning.

Lisa Nguyen (Environmental Textile Specialist, GreenFabric Solutions). From an eco-friendly perspective, using biodegradable detergents combined with a pre-soak in baking soda and water can effectively lift sunscreen stains without introducing harsh chemicals. It is important to avoid fabric softeners and dryer heat, which can reduce the swimsuit’s lifespan. Consistent, gentle care ensures both stain removal and sustainability in fabric maintenance.
