The life of a swimsuit varies depending on the quality of the garment and how it's taken care of. Generally, a swimsuit should last three months to a year, but if it's well-maintained, it can last for a few seasons.
It's generally advised to hand-wash all swimsuits, regardless of material. However, if hand-washing is not practical, choose a swimsuit made of cotton or a durable synthetic fabric, such as polyester or nylon, not spandex. The manufacturer's label will indicate whether the suit can be washed by machine.
Yes. Half a cup of baking soda added to a sink of cold water before soaking will both brighten a swimsuit and remove odors.
Competition swimsuits (men's types are often known as "jammers") are tight, compression garments made with a unique weave of fine spandex and polyester or Lycra fibers. It is even more important to rinse these thoroughly after each use. And reserve these swimsuits for competition use, as they are easily abraded and damaged when rubbed against concrete pool walls or pool decks.
