Chlorine bleaches in swimming pools quickly breakdown swimsuit fabrics.
Swimsuits used in the open water have much longer livers.
In either case, caring for your swimsuits will extend their lives.
- Hand-wash the swimsuit
- Gently wring the water out of the swimsuit
- hang-dry inside the shower, or place it where it can drip-dry
- While the sunshine will dry a swimsuit faster than inside the house, sunlight fades and break down the swimsuit fabrics.
- Avoid putting swimsuits in the dryer. High heat cooks the material, especially lycra, and it have a very short life.
- wash your swimsuit with soap and water while you’re in the shower, to save time; when you’re done, wrap your swimsuit in a towel to absorb the moisture, then hang it to dry.
