There’s nothing quite like finding the perfect swimsuit—whether it’s a bold-printed bikini, a sleek black one-piece, or a sparkle bikini that glistens under the sun. But after a few dips in the pool, a day lounging on the beach, or repeated washes, that once-vibrant bathing suit may start looking dull, faded, or even develop unsightly stains.

Understanding what causes discoloration can help you restore your swimwearOpens a new window and keep it looking brand new for seasons to come. In this guide, we’ll break down the best ways to wash and prevent a faded or stained swimsuit, so you can enjoy your favorite garment without worrying about losing its luster.

Chlorine & Saltwater Exposure

That refreshing swimming pool you love? It’s packed with chlorine, a powerful chemical designed to keep the water clean but also known for breaking down clothes' fabric fibers and stripping away your suit's vibrant hues. Over time, chlorine can leave your swimsuit looking dull, stretched, and even brittle.

Saltwater, on the other hand, has a drying effect on delicate materials like swimwear fabric, causing colors to fade and the fibers to lose their flexibility. This duo can significantly shorten the lifespan of your bathing suit if not properly cared for.

Sunlight & UV Damage

A sunny beach day might feel amazing, but UV rays can damage your swimsuit’s fabric. Just like prolonged sun exposure can cause your hair to lighten, it can also bleach bright colors from your favorite red swimsuitOpens a new window, black one-pieceOpens a new window , or blue swimwearOpens a new window. This damage is even more severe for sparkle bikinisOpens a new window and white bathing suits, as the sun intensifies discoloration, making them turn yellow over time.

Incorrect Washing & Drying

Washing your bathing suit incorrectly is one of the fastest ways to fade and weaken its material. Using hot water, bleach-based detergents, or a dryer can cause your swimsuit to stretch, discolor, or stiffen. Even something as simple as wringing it out too hard can cause damage to the fibers and material.

Vinegar Soak for Color Revitalization

A vinegar soak is a gentle yet effective way to clean chlorine buildup, remove stains, and bring back your swimsuit’s color. White vinegar works wonders in preserving delicate fibers while also eliminating harsh chemicals that strip away color.

1. Fill a basin with cold water and add ½ cup of white vinegar.

2. Put down your swimsuit and let it soak for 30 minutes.

3. Rinse thoroughly with cold water and let it air dry on a towel.

Baking Soda Solution for Stubborn Discoloration

If your swimsuit has stains, particularly from sunscreen or chlorine, baking soda can help remove them.

1. Mix one tablespoon of baking soda with one cup of water to create a paste.

2. Gently rub the paste onto discolored areas and let it sit for 15 minutes.

3. Rinse suit in cold water and lay flat to air dry.

Fabric Dye for Faded Dark Colors

For black one-piece swimsuits or dark bikinis that have faded over time, a fabric-safe dye can restore their original richness.

1. Choose a synthetic-fabric-friendly dye that matches your swimsuit’s original color.

2. Follow the product instructions carefully and always test on a small, hidden section first.

3. Rinse thoroughly and air dry to prevent further fading.

Rinse Immediately After Swimming

One of the easiest ways to prevent swimsuit discoloration is to rinse your suit immediately after swimming. Letting chlorine or saltwater sit on your swimwear fabric for too long causes discoloration and weakens the fibers.

• Use cold water to rinse the suit right after swimming.

• Avoid keeping a wet bathing suit in a plastic bag for long periods.

Hand Wash with Gentle Detergent

Hand washing is always the best method to clean swimwear without causing damage.

• Use a mild detergent (preferably one made for delicate fabrics or swimwear).

• Never use bleach, fabric softeners, or harsh chemicals.

• Gently massage the detergent into the swimsuit, then rinse thoroughly.

Air Dry in Shade

Never use a dryer, as the heat can weaken fibers and make colors fade faster.

• Lay the swimsuit flat on a towel to air dry.

• Avoid direct sunlight, as UV rays can cause discoloration.

• If hanging, use a drying rack instead of a hanger to prevent stretching.

Discoloration doesn’t mean you have to say goodbye to your favorite swimsuit. Using gentle restoration methods, and following proper care techniques, is all you need to keep your bathing suit looking fresh for many seasons.
