How to restore a white bathing suit to its original color

By Dr. Laundry June 29, 2012

What is the best was to restore a dingy, white bathing suit to its original pure white color?

It can be very difficult to keep an item white that picks up body soil and sunscreen that may also have a “hand wash in cold water” care label.  If the swimsuit contains any spandex, then using a sodium hypochlorite based bleach like Clorox® Regular-Bleach is out of the question.

To improve the appearance of your swimsuit, you can try an overnight presoak using powdered Clorox2® Stain Remover and Color Booster.  Dissolve 1 scoop powder in 2 gallons of very hot water, fully submerge the suit in the soaking solution, and let it soak overnight.  Use a dishwasher safe dinner plate to weigh it down if necessary so the suit is all way into the soaking solution.  Let it soak for up to 8 hours or overnight, then pour off the soaking solution and wash the swimsuit in the hottest water recommended on the care label using detergent and more Clorox2®.
