The first ten minutes
- Get it out of the liquid immediately and hold it with the ports facing down.
- Power it off. Do not check whether it still works. Water plus electricity causes short circuits and corrosion, and every second powered increases damage. If it is already off, leave it off.
- Do not plug it in. Charging a wet phone is the single most damaging thing you can do, and it is what people do first.
- Remove what comes out easily — SIM tray, memory card, case. This also opens drainage paths.
- Dry the outside with a soft cloth, and gently shake with ports facing down to clear standing water from the ports and speaker grilles.
- Leave it somewhere dry with airflow at room temperature. A fan moving air across it is genuinely helpful.
- Wait at least forty-eight hours before attempting to power it on. Longer is better. This is the hardest part and the most important.
Do not use rice. Rice absorbs ambient humidity slowly and does not draw water out of a sealed device. It also sheds starch dust and small fragments into ports. Open air with circulation dries a phone faster, and silica gel desiccant packs faster still.
Other things not to do
No hair dryer or heat source. Heat can damage the battery, warp adhesives and drive moisture deeper into the device rather than out of it.
No freezer. This circulates as folk advice and it is nonsense — it adds condensation and thermal stress.
No compressed air. High-pressure air pushes water further inside, past seals it had not yet crossed.
No shaking hard or repeatedly powering on to check. Each power-on attempt with moisture inside risks another short.
Not all liquids are equal
Clean fresh water is the best case. Modern phones with ingress protection ratings often survive it entirely. Water alone causes damage mainly through short circuits while powered and through slow corrosion of contacts afterwards.
Salt water is far worse. Salt is conductive and aggressively corrosive, and it keeps corroding after the water has evaporated. If a phone goes into the sea, rinsing briefly in clean fresh water before drying is counterintuitive but genuinely reduces long-term damage, because leaving salt inside guarantees ongoing corrosion.
Sugary drinks leave sticky residue that attracts moisture and gums up buttons and connectors permanently. Chlorinated pool water is corrosive. Sewage or dirty water adds contamination and a hygiene problem on top of the electrical one.
In every case except clean water, professional cleaning — which means disassembly and ultrasonic cleaning of the boards — dramatically improves the outcome, and it works best before corrosion has had days to develop.
Water damage indicators and warranty
Phones contain small indicator stickers that change colour permanently on contact with liquid, usually visible in the SIM tray slot. Service technicians check them, and a tripped indicator generally means liquid damage is excluded from standard warranty coverage.
This matters even for phones with ingress protection ratings. Those ratings describe performance in controlled laboratory tests when the device is new, and manufacturers typically exclude liquid damage from warranty regardless. Seals also degrade with age, drops and any repair that involved opening the device — so a two-year-old phone that has been dropped is not the sealed unit it was in the lab.
Useful things to own beforehand
Silica gel desiccant packs
Actually effective, unlike rice. Keep a sealed bag of them so they are dry when you need them. Tier: $.
Waterproof phone pouches
For paddling, beaches and boats. Cheap, and they let you use the phone through the pouch. Tier: $.
Rugged waterproof cases
For sustained exposure rather than an accidental splash. Adds real sealing on top of whatever the phone came with. Tier: $$.
Dry bags for electronics
The right answer for boats and kayaks, where the phone should be sealed and floating rather than merely resistant. Tier: $.
Realistic odds
A modern phone with an ingress rating, dropped briefly in clean water and powered off immediately, very often survives with no lasting problem. An older or previously repaired phone, in salt water, that stayed on and was plugged in to check, frequently does not.
Damage also appears late. A phone that seems fine for a week can develop faults as corrosion spreads — the symptoms are usually a distorted or dead speaker or microphone, a charging port that becomes intermittent, camera condensation, a battery that drains abnormally, or the phone becoming warm while idle. Any of those after a soaking indicates ongoing corrosion, and professional cleaning is more likely to help sooner than later.
Back up now, not later
The recoverable thing in most water incidents is the data, and only if it was already backed up. Automatic cloud backup for photos and messages costs little and turns a destroyed phone from a catastrophe into an expense. Do it before you need it, because a wet phone that will not power on is not a device you can back up.
The bottom line
Power off, do not charge, drain the ports, dry with moving air for at least forty-eight hours, and skip the rice. Rinse salt water off with fresh water before drying. Get professional cleaning for anything other than clean water, and expect the water damage indicator to have voided your warranty regardless of what the phone's rating says.
Why phones fail after water, mechanically
It helps to understand what is actually happening inside, because it explains why the advice is what it is. Water itself is not especially conductive when clean, but it dissolves whatever it touches — flux residue, dust, salts from your hands — and that solution conducts well. Current then flows between points on the board that were never meant to be connected, which is the short circuit that kills components while the phone is powered.
The second mechanism is electrochemical corrosion, and it continues long after the device is dry. Where dissimilar metals sit next to each other with a conductive residue between them, material migrates and connections degrade over days and weeks. That is precisely why professional cleaning matters more than drying, and why it works better early — drying stops the shorting risk but leaves the residue behind to keep working on the board.
Frequently asked questions
Does putting a phone in rice work?
No. Rice absorbs ambient humidity slowly and does not pull water out of a sealed device, while shedding dust into ports. Open air with circulation is faster; silica gel is faster still.
How long should I wait before turning it on?
At least forty-eight hours, and longer if you can bear it. Powering on with moisture still inside is what turns a survivable soaking into permanent damage.
My phone is waterproof — do I still need to worry?
Yes. Ratings reflect controlled lab tests on a new device, seals degrade with age and drops, and manufacturers generally exclude liquid damage from warranty regardless.
What if it went in salt water?
Rinse briefly in clean fresh water before drying. It sounds wrong but salt left inside keeps corroding indefinitely, and professional cleaning is strongly advisable.
It works fine now — am I in the clear?
Not necessarily. Corrosion damage often shows up days or weeks later as speaker, microphone, charging port or battery problems. Back up immediately and watch for those symptoms.
