Even if you don't have time to properly wash your swimsuit, a good rinse will help increase the life of your swimsuit. Always rinse your swimsuit thoroughly by hand with cold water after swimming. The fabric will retain its vitality better if you wash your swim by hand in cold water.
Soap
If you choose to use soap to wash your swimsuit, use only a mild, chemical-free soap.
Drying and storage
Air dry flat to avoid damaging the fabric fibers. To avoid mildew, make sure your swimsuit is completely dry before storing it. Never put your swimsuit in a washing machine or dryer. Otherwise, wash on a gentle cycle in a small laundry bag. Never dry clean, iron or bleach.
Stain
If you stain your swimsuit (pen mark, oil stain, food etc.), try using a chemical-free dish soap to remove the stain.
Heat
Direct or high heat will ruin the integrity of your swimsuit over time – nylon fibers can melt in high heat. Try not to swim in very hot water and never iron or dry your swimsuit in the dryer.
