Do You Really Need to Wash Your Swimsuit After Every Wear? Here's What an Expert Says

After a day at the pool or beach, it is tempting to toss your swimsuit over a chair and wear it again later. But swimsuits are exposed to chlorine, salt, sunscreen, sweat, body oils, sand, and bacteria. For that reason, experts generally recommend rinsing or washing your swimsuit after every wear.

Why Swimsuits Need Frequent Cleaning

Chlorine and salt water can weaken swimsuit fibers and fade colors. Sunscreen and body oils can cling to fabric, causing stains or odor. Even if you only swim briefly, the suit can still collect residue that affects stretch and fit over time.

Rinsing Is the Minimum

If you cannot wash your swimsuit right away, rinse it thoroughly in cool clean water as soon as possible. This helps remove chlorine, salt, and sand before they dry into the fabric. A quick rinse is much better than letting the suit sit damp in a bag.

How to Wash a Swimsuit

Hand washing is usually best. Fill a sink or basin with cool water and a small amount of gentle detergent. Swish the suit gently, rinse well, and avoid twisting or wringing, which can damage elastic fibers.

Can You Machine Wash It?

Some swimsuits can be machine washed on a delicate cycle, but hand washing is safer. If you use a machine, place the suit in a mesh laundry bag and use cold water. Avoid bleach and fabric softener.

Never Use the Dryer

High heat can ruin swimsuit elasticity. Lay the suit flat on a towel or hang it to dry away from direct sunlight. Avoid drying over a hot radiator or in a dryer.

Final Thoughts

Yes, you should clean your swimsuit after every wear, even if that only means rinsing it right away. Proper washing protects color, stretch, and freshness so your suit lasts longer through pool days, beach trips, and vacations.
