After sunbathing or a summer evening, immediately rinse your swimsuit in clear water to remove all impurities (sun cream, salt, chlorine...). This will keep your swimsuit looking lively!
Always wash by hand with a mild detergent, as the washing machine could damage the fibers of your swimsuit. However, by using a delicate program and placing your swimsuit in a washing net dedicated to lingerie, you can clean it in the washing machine with complete peace of mind.
Cold water is your best ally: it preserves the fabric's elasticity and won't damage the fibers. Avoid hot water, which can accelerate wear and tear. So wash cold or at 20° maximum!
Dry your swimsuit in the shade to prevent discoloration from UV rays. To keep your swimsuit in its original shape, hang it flat rather than hanging it up.
