White swimwear is a timeless and elegant choice for beachgoers and pool lovers alike. Its crisp, clean look exudes sophistication and pairs well with any beach outfit or accessory. However, maintaining that pristine, bright white appearance can be surprisingly challenging. Exposure to chlorine, saltwater, sunscreen, sweat, and even sand can cause white swimsuits to yellow, fade, or develop stubborn stains over time, diminishing their appeal. This comprehensive guide will walk you through the best practices and insider tips to keep your white swimwear looking fresh, bright, and as good as new for many seasons.

Before diving into care tips, it's important to understand the reasons behind the discoloration of white swimwear:
- Chlorine and Saltwater Exposure: Chlorine in pools and salt in seawater are harsh on fabric fibers. They can break down the material's structure, causing yellowing or fading over time.
- Sunscreen and Body Oils: Sunscreens, particularly those with chemical UV filters, along with natural body oils and lotions, can leave stains that are difficult to remove from white fabric.
- Sweat and Dirt: Sweat contains salts and minerals that accumulate and discolor fabric, especially if the swimsuit is not rinsed promptly.
- Sun Exposure: Prolonged exposure to direct sunlight can cause yellowing and weaken the elasticity of the fabric, leading to premature wear.
- Improper Washing: Using harsh detergents, hot water, or machine washing can damage the delicate fibers and accelerate discoloration and fabric degradation.
Understanding these factors is the first step toward protecting your white swimwear and extending its lifespan.
The most crucial step in preserving white swimwear is to rinse it immediately after swimming. Use cool, fresh water to wash away chlorine, salt, sunscreen, and sweat residues. This prevents chemicals from settling into the fabric and causing discoloration or damage. Be sure to rinse both the inside and outside of the swimsuit thoroughly to remove all residues.
Always hand wash your white swimwear to avoid the agitation and harsh treatment of machine washing, which can weaken fabric fibers and fade colors. Use cold water and a mild detergent specifically designed for delicate fabrics or swimwear. Avoid bleach and harsh chemicals, as they can cause yellowing and fiber damage.
Hot water can set stains and degrade the elasticity of your swimsuit. Cold water helps preserve the fabric's integrity and keeps the white color bright. Always opt for cold water washing and rinsing.
To restore whiteness and remove stubborn stains, soak your swimsuit in a natural whitening solution. Here are some effective options:
- Baking Soda: Mix four tablespoons of baking soda in cold water and soak the swimsuit for 30 minutes. Baking soda acts as a gentle fabric softener and stain remover.
- White Vinegar: Add one cup of white vinegar to cold water and soak for 30 minutes. Vinegar deodorizes and brightens fabric without harsh chemicals.
- Lemon Juice and Salt: Spray a 50/50 mixture of lemon juice and water on stains, then let the swimsuit dry in the sun. This natural bleaching effect helps lift discoloration.
These natural agents are safe for delicate swimwear fabrics and help maintain whiteness without damage.
Never wring or twist your swimsuit to remove excess water, as this can stretch and damage the fabric fibers. Instead, gently press the water out by placing the swimsuit between two clean towels and pressing down to absorb moisture.
Lay your swimsuit flat on a towel or drying rack in a shaded, well-ventilated area. Avoid direct sunlight, which can cause yellowing and fabric degradation. Hanging swimsuits for drying can stretch out the fabric due to gravity, so flat drying is best to maintain shape and elasticity.
If you swim frequently, invest in multiple swimsuits and rotate their use. This allows each piece to dry completely and reduces wear and tear, helping all your swimsuits last longer and stay brighter.
Sunscreen and tanning oils are common culprits for staining white swimwear. To treat these stains:
- Remove excess oil by sprinkling sand on the stain and letting it absorb for about 15 minutes.
- Pretreat the area with a gentle swimwear detergent or mild dish soap, gently rubbing the fabric.
- Soak the swimsuit in cold water mixed with detergent before washing.
Self-tanner stains can be tricky but manageable:
- Flush the stained area with cold water from the inside out to push the stain out of the fabric.
- Apply dish soap mixed with warm water on the stain and gently sponge.
- Rinse and wash immediately; repeat the process if necessary.
For these common beverage stains:
- Blot the stain immediately to remove excess liquid without rubbing.
- Soak the swimsuit in cold water with a splash of oxygen-based bleach or salt.
- Gently scrub the stained area and rinse thoroughly.

1. Rinse immediately after use with cold water to remove chemicals and oils.
2. Soak in cold water with baking soda or vinegar for 30 minutes if the swimsuit looks dull or stained.
3. Hand wash gently with mild detergent in cold water.
4. Rinse thoroughly to remove all detergent residues.
5. Press out excess water by placing the swimsuit between two towels.
6. Dry flat in the shade, avoiding direct sunlight and hanging.
- Avoid using bleach and fabric softeners, which can damage swimwear fabric.
- Do not machine wash or tumble dry unless the care label explicitly permits it.
- Avoid ironing your swimsuit as heat can damage the elastic fibers.
- Store swimwear flat or loosely folded to maintain its shape and elasticity.
Keeping your white swimwear white requires consistent care and attention to detail. By rinsing immediately after use, hand washing with gentle detergents in cold water, utilizing natural whitening agents for stains, and drying properly in the shade, you can preserve the brightness and elasticity of your swimsuit for many seasons. Avoid harsh chemicals, hot water, and machine washing to prevent damage and yellowing. With these expert tips, your white swimwear will continue to look fresh, clean, and stunning every time you hit the beach or pool.




It's best to rinse your swimsuit after every use to remove chlorine and oils and wash it thoroughly after 3 to 5 wears to avoid excessive wear from frequent washing.
No, bleach is too harsh for swimwear fabrics and can cause yellowing and fiber damage. Instead, use natural whiteners like baking soda or white vinegar.
Yellowing is caused by chlorine, sunscreen, body oils, sweat, and prolonged sun exposure. Improper washing and drying methods can also contribute to discoloration.
Generally, no. Machine washing can damage the fabric and cause fading. Hand washing in cold water is recommended unless the care label explicitly states that machine washing is safe.
Dry your swimsuit flat in a shaded, well-ventilated area. Avoid direct sunlight and never use a tumble dryer or wring the fabric, as these can cause damage and yellowing.
