RINSE THEM ASAP
Every suit needs a rinse even after sunbathing. Sunblock and the body’s oils can do damage. Rinse immediately after being in a hot tub or pool that uses chlorine.
We would highly recommend hand washing your suits. The issue with washing machines is that they agitate all the delicate parts (like the cups, padding, ties, etc.). All of these movements can damage a delicate suit, leaving things bunched, stretched, or otherwise ill-fitting.
SOAP IT UP
A standard laundry detergent can be too harsh for your suit. Make sure you rinse all soapy suds out. And we mean, do rinse it well. You wouldn’t want to see mounds of foam the next time you hop in to a pool.
Resist the urge to wring out every last drop of water. Doing so can damage the fibers, leaving your suit sagging in all the wrong places. Hanging a swimsuit (especially by the ties) can stretch it out, too. Instead, lay the suit out on a towel, roll the towel up and squeeze gently, then lay your swimsuit out to dry. Avoid drying it in sunshine, which can result to the colors fading. Always dry the suit out completely before putting it away.
Spandex is a “memory fabric”, meaning it needs a full day to snap back to its usual position. If you’re on vacation or would wearing bathing suits often, it’s essential to have more than one, so that each suit has 24 hours to bounce back (not to mention time to wash and dry it completely).
KEEP IT COOL
Hot water is bad for swimsuits. Never wash your bathing suit in hot water, and avoid too many dips in the hot tub with your favorite suit. Can’t resist the hot tub? Reserve one swimsuit mainly for your hot tub use!
SIT ON A TOWEL
Whenever you’re sitting on the grainy sands of the beach, pool, a wooden bench, or on any other rough surface, always sit on a towel when wearing your suit. Those impromptu seats can snag and tear the material. If carrying a towel 24/7 seems too high maintenance, simply wrap-up in a sarong when you leave your lounge chair — you’ll never even have to think about where you’re sitting (though the sarong will take the brunt of the blow, so make sure you won’t mind snagging it).
