The daily wear and tear of a swimsuit isn't luxurious as one might think. Between the sun, chlorine, direct sunlight, salt water and constant stretching, it is important to take proper care of your little guy. Sweat and body oils cause the materials used in most swim suits to breakdown. Therefore, to keep your suit tight and perky, prompt washing is necessary. Caring for your swimsuits is easy and should be done by hand. If washing in a machine is necessary, be sure to use a mesh bag for intimates, mild detergent and a delicate wash cycle.
