A phone dropped in a swimming pool is not quite the same as a phone dropped in a sink. The water itself is only half the problem. Pool water is chlorinated, and chlorine — along with the other chemicals used to keep a pool clean — leaves residue behind as it dries. That residue keeps working on your phone’s speaker mesh, charging port and internal contacts long after the splash is forgotten. The good news is that the extra care a pool dunk needs is simple, and it starts in the first few minutes.

Get it out, switch it off, and do not charge it

The first steps are the same as for any wet phone, and speed matters more than perfection:

1. Fish it out as quickly as you can. Every extra minute submerged is more water finding its way in.
2. Switch it off if you can do so safely. A powered-on phone with water inside is more likely to short. If the screen is already misbehaving, just leave it alone and get it dry.
3. Do not plug in a charger. Not to “see if it still works”, and not because the battery is low. A wet charging port plus power is how corrosion and short circuits happen. Wait until the port is fully dry.
4. Dry the outside. Wipe the phone with a soft, lint-free cloth, hold it speaker-side down, and give it a gentle shake so loose droplets fall out.

For the full sequence, our guide to first aid for a phone dropped in water covers each step in detail. What follows is what is different about pool water.

Why pool water is worse than fresh water

Fresh water is relatively kind to electronics: it evaporates and, if it dries cleanly, leaves little behind. Pool water is deliberately treated water. Chlorine, and the salts and other chemicals dissolved in it, do three things fresh water does not:

• They leave residue. As pool water dries on the speaker mesh, a thin film of chemical residue stays behind. That film can keep the mesh stiff and the sound muffled even after the phone feels dry.
• They corrode. Chlorine compounds attack metal contacts over time. The damage is slow — days or weeks, not minutes — which is why a phone can sound fine the day after a pool dunk and develop charging or speaker problems later.
• They attract moisture. Salt and chemical residues are hygroscopic, meaning they pull moisture from the air. A mesh coated in residue stays slightly damp for longer, which feeds the corrosion cycle.

Salt water does the same thing more aggressively, as explained in our guide to salt water in a phone speaker. Pool water sits between fresh water and seawater in severity — less corrosive than the sea, but not something to ignore.

Rinse it — yes, really rinse a wet phone

It feels wrong, but the standard advice for phones soaked in anything other than clean water is to rinse briefly with clean, fresh water. The logic is simple: a few seconds under gentle fresh water removes the chlorine and salts that would otherwise dry onto the phone and corrode it, and fresh water on its own is far less harmful than the residue it washes away.

How to do it safely:

• Power the phone off first, if it is still responding. If it will not switch off, do not force the issue — just keep the rinse brief.
• Use a gentle flow, not a jet. A slow stream from a tap, or a jug of clean water poured gently over the phone, is enough. Do not use a shower head on full blast or hold the phone under a running tap for minutes.
• Focus on the openings. Let the water run over the speaker grille, the charging port area and any other openings where pool water got in.
• Keep it brief. Ten to twenty seconds is plenty. You are washing residue off the surface and out of the mesh, not giving the phone a bath.
• Dry it immediately. Wipe it down, shake it gently speaker-side down, and pat the openings with a soft cloth.

Do not use soap, alcohol, or any cleaning product for the rinse — plain clean water is what you want. And do not rinse a phone that is already showing signs of serious internal water damage, such as a flickering screen, swelling, or a hot battery. In that case, switch it off and get it to a repair shop instead.

Eject the water from the speaker

Once the phone is rinsed and wiped, run a water-eject tone to clear the speaker mesh:

1. Set the media volume to around three-quarters — loud enough to feel the vibration, not at maximum.
2. Open the free speaker cleaner and run the water-eject sound, holding the phone with the speaker pointing down.
3. Wipe away any droplets that appear around the grille, then repeat two or three times with short pauses.
4. Test with a song afterwards. The sound should be clearer, even if it is not perfect yet.

If your phone is an iPhone, the same steps apply — our iPhone water-eject guide covers the iPhone speaker layout specifically. The rinse-first step is the part people skip, and it is the part that matters most after a pool dunk.

Drying time, and what to watch for afterwards

A pool-dunked phone needs longer to dry than a lightly splashed one. Leave it in a well-ventilated room, speaker-side down on a dry cloth, for at least 24 hours before you judge the speaker. The sound often improves gradually as the last moisture evaporates. Realistic drying times are set out in our guide to how long it takes to get water out of a phone speaker.

While it dries, avoid the usual mistakes: no rice (it does very little and leaves dust in the ports — see does rice fix a wet phone), no hair dryer, no radiator, and no charging until the port is fully dry. If your phone shows a moisture warning, believe it.

In the days after a pool dunk, watch for delayed symptoms: a speaker that sounds fine one day and crackly the next, a charging port that becomes fussy, or a battery that drains faster than usual. Those can be signs of residue or corrosion developing, and they are worth getting checked early, while a clean-up is still cheap.

What never to do after a pool dunk

• Do not charge a wet phone. This is the single most damaging mistake, and it applies to every kind of water.
• Do not use a hair dryer or compressed air. Heat pushes moisture deeper, and compressed air can drive water further into the phone.
• Do not poke the speaker mesh. Pins, toothpicks and SIM ejector tools tear the mesh and push residue in, not out.
• Do not assume “water resistant” means “pool proof”. Water-resistance ratings are tested in fresh water in a lab, on a new phone. Pool chemicals, heat, and an older phone’s worn seals all reduce the protection in practice.
• Do not leave it in a wet case or pocket. Take the case off so air can reach every edge of the phone.

Frequently Asked Questions

My phone fell in the pool. Is it ruined?
Not necessarily. Most pool dunks are recoverable if the phone is retrieved quickly, rinsed, ejected and dried properly. The risk is residue and corrosion over time, which is why the rinse step matters.

Should I rinse my phone after it falls in a pool?
Yes — a brief, gentle rinse with clean fresh water removes chlorine and salts before they dry onto the speaker mesh and contacts. Power the phone off first, keep the rinse short, and dry it straight away.

Can chlorine damage a phone speaker?
Chlorine itself does not usually kill a speaker outright, but the residue it leaves behind can stiffen the mesh and corrode contacts over days and weeks. That is why pool water needs a rinse, where fresh water does not.

How long should I wait before charging after a pool dunk?
Until the charging port is completely dry — at least 24 hours, and longer if the phone still shows a moisture warning. Never charge a phone with a wet port.

Will a water-eject sound get pool water out of the speaker?
It clears the mesh, which is where the muffled sound comes from. It does not remove chemical residue on its own, so rinse first, then run the tone, then dry thoroughly.

The speaker sounded fine after the pool, then went muffled a week later. Why?
Residue drying and corrosion developing over time. Get the phone inspected — a professional clean-up can still help, but the sooner the better.

Try it now

If your phone has just come out of a pool, rinse it briefly, run the free speaker cleaner with the speaker pointing down, and then give it a full day to dry. The rinse feels counterintuitive, but it is the step that protects your phone in the weeks after the splash, not just the day of it.
