Phone got salt water, pool water or a drink in the speaker? What to do
Short answer
If a water-resistant phone is exposed to salt water, pool water, soda, coffee or other liquids, both Apple and Samsung advise rinsing the affected area with fresh tap water, then drying it. The rinse washes out salt, chlorine or sugar before it dries into residue inside the speaker grille and ports. Afterwards, tap it dry with the openings facing down, run a 165 Hz water eject cycle to clear the speaker, and don't cable-charge until the port is completely dry.
Plain fresh water evaporates and leaves almost nothing behind. Everything else is different. Sea water leaves salt crystals, pool water leaves chlorine compounds, soda and juice leave sugar, coffee and beer leave sticky residue. That residue dries on the speaker mesh and inside the charging port — which is why a speaker that sounded fine an hour after a beach trip can go dull or crackly a day later.
Why rinsing with fresh water is the right move
It sounds wrong to put a wet phone under a tap, but it's what the manufacturers say. Apple's iPhone water-resistance guidance says that if the phone is exposed to a liquid other than water, you should rinse the affected area with tap water, then wipe it off and dry it. Samsung gives similar advice for Galaxy phones exposed to salt water, chlorinated water or other liquids. A brief rinse dilutes and washes out the residue while it's still dissolved — once it has dried, it's much harder to remove.
Only do this on a water-resistant phone that's intact. If the back glass or screen is cracked, or the phone isn't rated at least IP67, skip the rinse, dry it and get it looked at.
Step by step
- Get it out and dry the outside with a lint-free cloth. Take the case off.
- Rinse briefly under gently running, lukewarm-to-cool fresh tap water — a few seconds over the speaker and port areas. Not a pressure jet, not hot water, and don't submerge it.
- Shake and tap it dry with the speaker and port facing down.
- Clear the speaker with sound. Run the Water Ejector speaker-down over a cloth, two or three times with breaks in between. Clearing water out of the mesh also takes the dissolved residue with it.
- Air dry in a ventilated spot, with a fan on cool if possible.
- Wait before cable charging — at least 30 minutes, up to 24 hours if the phone shows a liquid detected or moisture detected warning. Wireless charging is fine once the back is dry.
Liquid by liquid
| Liquid | What it leaves behind | What to do |
|---|---|---|
| Sea water | Salt crystals, corrosion risk | Rinse soon, dry, water eject cycle |
| Pool water | Chlorine compounds | Rinse, dry, water eject cycle |
| Soda, juice, coffee with sugar | Sticky sugar film | Rinse, dry, water eject; brush grill gently once dry |
| Beer, wine | Sugar and residue | Rinse, dry, water eject |
| Sweat | Salt (in small amounts over time) | Wipe after workouts; occasional water eject cycle |
| Soapy water, shampoo | Surfactants that can pass seals more easily | Rinse, dry, water eject; avoid using phones in the shower |
| Fresh tap or rain water | Almost nothing | Dry and water eject — no rinse needed |
Why the speaker suffers first
The loudspeaker sits behind the largest open mesh on the phone. Its job is to move air, so it can't be sealed like the rest of the phone — the protection comes from a water-resistant membrane and fine mesh. Residue that dries on that mesh blocks sound directly. That's also why a quick sound cycle after the rinse matters: it physically pushes the water, and whatever is dissolved in it, back out through the grille.
If the speaker is still dull a day later
- Run the Dust Buster sweep to break up dried residue.
- Brush the outside of the grill gently with a soft dry toothbrush — see safe speaker grill cleaning.
- Test with the speaker test. Crackling at every volume suggests the liquid reached the speaker itself.
Salt water is the most likely of these to cause lasting corrosion, so if the phone behaves oddly after a sea dunk — random reboots, charging faults, a warm idle phone — get it checked promptly.
Frequently asked questions
Should I rinse my phone after it gets salt water in it?
Yes, if it's an intact water-resistant phone. Apple and Samsung both advise rinsing the affected area with fresh tap water after exposure to liquids other than water, then drying it thoroughly.
Is pool water bad for phones?
Chlorinated pool water is harsher than fresh water and can degrade seals over time. Water resistance ratings are tested in fresh water, so swimming with a phone isn't recommended. Rinse, dry and clear the speaker after any exposure.
I spilled soda on my phone speaker. What should I do?
Rinse the area briefly with fresh water to dissolve the sugar, dry it with the speaker facing down, run a water eject cycle, and once it's dry, brush the grill gently to lift any remaining film.
Does water eject work for salt water?
It clears the water from the speaker grille, and with it much of the dissolved salt — but rinse with fresh water first so less salt is left to dry on the mesh.
