Quick answer
Rinse your period swimwear in cold water right after swimming, wash it gently with mild detergent, then air-dry it flat away from direct heat. Store it dry and unfolded to keep the absorbent layers effective.
Why rinsing right after swimming matters
Chlorine, salt, and sunscreen can break down the elastic and absorbent fibres in period swimwear over time. A quick cold rinse removes these residues before they set in, which helps the fabric stay snug and leak-proof.
Delaying the rinse lets chemicals linger longer, which can shorten the life of the garment. Even if you are not swimming again soon, a 30-second rinse makes a big difference.
Choosing the right detergent
Harsh detergents, fabric softeners, and bleach can clog or degrade the moisture-wicking and absorbent layers. Stick to a mild, fragrance-free detergent and avoid any additives that leave residue.
If you are unsure whether a detergent is safe, check the label for 'gentle' or 'free and clear'. When in doubt, a small amount of baby shampoo is a safe alternative.
What to avoid in the dryer
High heat from a tumble dryer can melt or warp the synthetic fibres in swimwear, reducing stretch and absorbency. Air-drying is the only safe method for period swimwear.
Direct sunlight can fade colours and weaken elastic, so dry in a shaded, well-ventilated spot. Hanging by the straps can stretch them, so lay the garment flat on a towel instead.
Step-by-step care routine
- Rinse in cold water: Immediately after swimming, rinse your period swimwear under cold running water until the water runs clear. Gently squeeze—do not wring—to remove excess water. Checkpoint: If you cannot rinse right away, at least keep the garment damp in a wet bag until you can.
- Wash with mild detergent: Hand wash in a basin of cold water with a small amount of mild, fragrance-free detergent. Swish gently for a few minutes, then rinse thoroughly until no soap remains. Checkpoint: Never use fabric softener, bleach, or a washing machine—these can damage the absorbent layers.
- Air-dry flat: Lay the swimwear flat on a clean, dry towel in a shaded area. Roll the towel to press out extra moisture, then unroll and let it air-dry completely away from direct sun and heat. Checkpoint: Do not hang by the straps or use a dryer; both can stretch or warp the fabric.
- Store dry and unfolded: Once fully dry, fold the swimwear loosely and store it in a drawer or breathable bag. Avoid tight folding or stacking heavy items on top, which can crush the absorbent core. Checkpoint: Store in a cool, dry place to prevent mildew and keep the elastic fresh.
