After swimming: rinsing off chlorine, salt and sand

20 October 2026

You are on a beach holiday with friends, and everyone heads back up the sand to change. There is no proper changing room, just a cold outdoor tap and a row of towels. You wrap yours twice, keep your wet shorts on far longer than you want to, and tell the others you will catch them up at the bar. Someone jokes that you are taking ages, and you feel the heat in your face while you laugh it off.

If that sounds familiar, you are not alone. Plenty of adults feel awkward about rinsing and changing after a swim, especially when the facilities are basic. This article covers simple, gentle habits for after the pool or the sea, so you can get comfortable again without fuss.

Why a rinse after swimming is worth the effort

Pool water and sea water both leave something behind on your skin. In a pool it is the smell of the water and whatever is added to keep it clean. In the sea it is salt, and often a little sand that finds its way into places you did not expect.

Some people find their skin feels dry, tight or itchy if this is left on for hours. A quick rinse with fresh water is a simple way to feel more comfortable. It does not need to be long or thorough. A minute or two is usually enough.

Rinsing after the pool or the sea

If there is a shower, use it. If there is only an outdoor tap or a bottle of water, that is fine too. The aim is just to wash away chlorine smell, salt and sand with clean, fresh water.

A simple rinse

1. Use lukewarm water if you can, rather than hot.
2. Rinse the whole groin area with water first.
3. If you are uncomfortable, gently ease your foreskin back only as far as it goes easily. Never force it.
4. Rinse underneath with plain water, or a small amount of mild, unscented soap.
5. Rinse well so no soap is left behind.
6. Gently return your foreskin to its usual position.

Plain water is often enough after a swim. If you use soap, keep it mild and rinse it off fully. Strongly scented shower gels can leave some people feeling irritated, so a simple bar or a gentle wash is a calmer choice.

When the shower is in full view

Open showers at a beach or lido can feel exposed. You can rinse with your swimwear still on, then do a fuller wash later in your room or at home. You can also take a small bottle of fresh water into a toilet cubicle. There is no rule that says you must rinse in front of anyone.

Drying gently

Once you have rinsed, take a moment to dry properly. Damp skin under a foreskin can feel uncomfortable, especially on a warm day when you are walking around for hours afterwards.

• Pat dry with a soft, clean towel rather than rubbing.
• Dry under the foreskin gently, if it draws back easily.
• Let the area air for a minute if you have the privacy.
• Shake sand out of your towel before you use it.
• Keep a separate small towel for drying, away from the sandy beach towel.

If you are short on time, a quick pat with a dry corner of your towel is still better than pulling clothes on over wet skin.

Getting out of wet swimwear

Sitting in damp swimwear for a long time can feel clammy and uncomfortable. Sand trapped in the lining can rub as you walk. Changing soon after your swim is a small habit that makes the rest of the day more pleasant.

Packing for an easy change

• A dry pair of breathable cotton underwear.
• Loose shorts or trousers to change into.
• A large towel or a changing robe for privacy.
• A small bottle of fresh water for rinsing.
• A bag to keep wet swimwear away from dry clothes.

A changing robe or a large towel with a drawstring can make beach changes much less stressful. If you would rather change in a cubicle or wait until you are back in your room, that is a perfectly reasonable choice. Just try not to stay in wet swimwear for hours if you can help it.

When you get home, rinse your swimwear in fresh water and let it dry fully before you wear it again.

When to talk to a doctor

Most of the time, a rinse and a change are all you need. But if something does not feel right, it is sensible to get advice. Doctors see these questions often, and you do not need to feel embarrassed.

Consider booking an appointment with a GP if you notice any of the following, especially if it lasts more than a few days:

• Soreness, itching or redness that does not settle.
• Pain when you pass urine.
• An unusual discharge or a smell that does not go away with gentle washing.
• Your foreskin feels tight, or harder to draw back than usual.
• Any swelling, cracks or skin that looks different to you.

If you are receiving treatment for the area, follow the advice you have been given about swimming and washing.

If your foreskin has been drawn back and will not return to its usual position, or you have severe pain or swelling, do not wait. Contact a medical service straight away. In the UK, call 999 in an emergency, or NHS 111 for urgent advice. In Australia, call 000 in an emergency, or healthdirect on 1800 022 222 for advice.

Summary

After a swim in a pool or the sea, rinse with lukewarm fresh water to wash away chlorine smell, salt and sand. Use plain water or a little mild soap, and never force your foreskin back. Pat dry gently, and change out of wet swimwear into breathable cotton underwear when you can. Find a private spot if that helps you feel at ease. If anything feels sore, tight or different and does not settle, talk to GP.
