Learn how to wash a swimsuit, care for swimwear, and extend swimsuit life with a simple, ordered routine that protects stretch, color, and fit.
Quick answer
Rinse your swimsuit in cool water immediately after every wear, wash it by hand with a mild detergent, and lay it flat to dry away from direct sun. Skip the washer, dryer, and wringer. This routine is the fastest way to make a swimsuit last.
Swimwear wears out faster than almost anything else in your closet because it faces a triple threat: chlorine or salt, sunscreen and body oils, and the stretch of every wear. The good news is that most of the damage is preventable with a routine that takes about two minutes.
Whether you are caring for a bright one-piece like the Eclipse One Piece or a simple black suit you wear weekly, the same habits apply. Below is an ordered swimwear care process, with the mistake to avoid at each step.
Why swimwear care matters more than you think
Swim fabric is built to stretch and recover, but chlorine, salt, and sunscreen residue break down elastic fibers over time. That is why a suit that felt snug in June can feel loose by August. Rinsing and washing remove those residues before they can do lasting damage.
Heat is the other culprit. Hot water, hot dryers, and hot car trunks all speed up fiber breakdown. Cool water and air drying are the two easiest levers you control.
- Chlorine and salt weaken stretch fibers; sunscreen and oils attract grime.
- Heat and harsh detergent cause fading, pilling, and loss of shape.
What you need before you start
You do not need special equipment. A clean sink or basin, cool water, and a mild detergent are enough. Avoid wool wash, fabric softener, and anything labeled with bleach or enzymes, since these can degrade stretch fabrics.
Keep a dedicated mesh bag or a small travel bottle of mild detergent in your swim bag so rinsing happens before the suit sits in a hot car.
- Mild liquid detergent or swim-specific wash
- Cool water and a clean basin
- A flat drying spot out of direct sun
Your 7-step swimwear care routine
- Rinse immediately after every wear: Rinse your swimsuit in cool water as soon as you leave the pool or beach. This removes chlorine, salt, and sunscreen before they set into the fibers. Mistake to avoid: letting a damp suit sit in a bag or hot car for hours.
- Wash by hand with mild detergent: Fill a basin with cool water and a small amount of mild detergent. Gently squeeze the suds through the fabric for about a minute, focusing on areas that contact sunscreen and sweat. Mistake to avoid: using regular laundry detergent or fabric softener, which can leave residue and break down stretch.
- Skip the washing machine and dryer: Even a gentle cycle can stretch straps and abrade fabric against the drum. If you must use a machine, place the suit in a mesh bag on a delicate cycle, but hand washing remains the safer choice. Mistake to avoid: assuming a gentle cycle is the same as hand washing. It is not.
- Rinse thoroughly until water runs clear: Squeeze, do not wring, and rinse until no suds remain. Leftover detergent can attract dirt and irritate skin. Mistake to avoid: wringing or twisting, which distorts the shape and weakens seams.
- Lay flat to dry in the shade: Lay the suit flat on a clean towel away from direct sunlight. If you hang it, use a thick padded hanger and avoid hanging by thin straps, which can stretch them out. Mistake to avoid: drying in direct sun or on a hot radiator, which fades color and damages elastic.
- Rotate between at least two suits: Elastic needs time to recover between wears. Rotating two suits gives each one a rest day and roughly doubles the lifespan of both. Mistake to avoid: wearing the same suit every day and expecting it to hold its shape all season.
- Store clean and dry, not damp: Once fully dry, store your suit flat or loosely folded in a drawer. Never store it damp, and keep it away from rough zippers or hooks that can snag fabric. Checkpoint: if the suit still smells like chlorine after washing, repeat the rinse step before storing.
Product facts that affect how you care for your suit
- Eclipse One Piece: Adjustable straps and a graphic strappy back. Straps and back details are the first places to stretch or snag, so rinse and lay flat rather than hanging by the straps.
- Piper Oversized Rain Jacket: Fully seam-sealed and packable, designed to pack into its own backpack. A packable outer layer is useful for swim days when you need to change after a rinse and keep damp items separate from dry clothes.
Swimwear care comes down to a few consistent habits: rinse right away, wash gently by hand, dry flat in the shade, and rotate your suits. Do that, and you will get more seasons, better fit, and less fading from every swimsuit you own.
