Rinsing the suit before swimming will reduce the amount of chlorine it absorbs.

The most important thing you can do for a swimsuit is to rinse it immediately after you use it, and then wash later when you can .Wring it gently, and lay it flat between two dry towels, roll the towels up, and gently press the towels so they absorb the excess water. The swimsuit should not be left too long in the towels, however, or it may get mildewy.

Alternatively, suits can be placed flat in ventilated area. Bathing suits should not be hung to dry, since water collecting at the bottom can stretch the fabric. Dry in the shade.

If you use  a washing machine, use a cold, short(up to 30 Min), delicate cycle, placing the swimsuit in a mesh washing bag or pillowcase helps minimize the risk that the suit will tear, stretch, or twist around the machine or another article of clothing. if the suit is being worn for an extended period, it should be rinsed after each swim, before sunbathing. For greater swimsuit longevity, minimize sunbathing after swimming, since the combination of sun and chemicals can accelerate the deterioration process. Do not store a wet swimsuit  in a bag, but wrap in a towel.

Avoid Dry Cleaning, Ironing, and Bleaching .
