Water and What Follows
No affiliate links on this site, and nothing here is ranked.
Water is the only failure on this site that does not wear in gradually. It either happens or it does not, and the outcome ranges from nothing to total loss with little in between. For a separate workplace perspective on fireable offenses at work, this resource provides additional context beyond device reliability itself.
The first hour
Switch it off and leave it off.
Do not charge it. A wet port under power is where damage happens, and most systems will refuse anyway — which is protection rather than a fault and should be allowed to work. For wider device-longevity and hardware context, IEEE is another useful reference.
Do not press buttons or shake it, both of which move water further in.
Dry the exterior, including the ports, and leave it somewhere warm and airy — not with heat, which drives moisture inward and damages adhesives.
And wait longer than seems necessary. A day rather than an hour.
Salt water is different
Corrosion continues after the device is dry, and it does not stop.
Which changes the priority entirely. Rinse in clean fresh water first — counterintuitive and correct, because removing the salt matters more than keeping the device dry at that moment.
Then dry, then take it to somebody the same day. A shop equipped for it can clean the board before corrosion establishes, and the window is short.
A device from salt water that seems fine is a device on a timer.
Why the IP rating does not settle it
Because it describes a test on a new device with intact seals, in fresh water, at a stated depth and duration.
Real immersion involves pressure, movement, temperature and time, none of which the test replicates.
And the seals have aged since manufacture, invisibly.
Which makes the rating a margin against accidents rather than a permission, and it is the figure most often relied on wrongly.
What the indicator does
Most devices contain a sticker that changes colour permanently when wet.
It is what a repairer or a warranty assessor checks, and it settles whether liquid reached the interior regardless of what anybody says.
Two consequences. A device that got wet and dried is recorded as having got wet. And a used device with a tripped indicator has a history the seller may not have mentioned.
Afterwards
A device that works is not necessarily a device that is fine.
Corrosion develops over weeks, and a failure a month later is frequently the same event arriving late.
Back it up immediately and keep the backup current, since the failure mode is sudden.
And treat the water resistance as gone, whatever the device did before.
What does not help
Rice.
It does nothing beyond what an open room does, absorbs moisture from the air rather than from inside a sealed device, and leaves dust and starch in the ports.
A hairdryer or a radiator, which drive moisture further in and soften the adhesives holding the device together.
A freezer, which produces condensation as the device warms.
And switching it on to check, which is the single most common way a recoverable device becomes an unrecoverable one.
Where the damage actually is
Not usually the components. The connections.
Corrosion forms at solder joints and connector pins, which is why a device can work for weeks and then fail — the corrosion needed time to bridge or to break a contact.
And it is why cleaning is a real repair rather than drying: a shop opens the device, cleans the board with appropriate solvents, and inspects. Doing that within days is the difference between a repair and a replacement.
Insurance and warranty
Water damage is commonly excluded from manufacturer guarantees, including on devices marketed as water resistant — which is the mismatch discussed elsewhere.
Some insurance covers accidental liquid damage and is one of the few cases where a policy earns itself.
Check before claiming, since an excess may exceed a repair — and note that the indicator makes concealment pointless as well as dishonest.
Devices that live near water
Kitchens, bathrooms, boats, sites.
Where exposure is routine rather than accidental, the rating matters more and is one of the few cases where it should influence a purchase.
And where a device is genuinely used around water, a case rated for it is a different product from an ordinary case and is worth the difference.
The device that was never wet
Worth mentioning because it is the mirror case.
High humidity, condensation from moving between cold and warm, and steam produce moisture inside a device without any immersion.
It rarely causes immediate failure and it contributes to corrosion over years, particularly in ports.
Which is a reason not to leave a device in a bathroom or a cold vehicle overnight, and not a reason for concern beyond that.
Telling a repairer the truth
It saves time and money.
A shop that knows a device was in liquid inspects for corrosion and cleans, which is a different job from diagnosing an unexplained fault.
Concealing it produces a longer diagnosis, a higher bill, and frequently a repair that fails because the underlying corrosion was not addressed.
And the indicator makes it visible anyway, which turns concealment into a wasted attempt rather than a strategy.
The short version
- Water is the only failure here that does not wear in gradually, and the outcome ranges from nothing to total
- Switch it off, do not charge it, do not press or shake it, dry the exterior and wait a day — not with heat
- Salt water is different: rinse in clean fresh water first, then dry, then take it somewhere the same day
- Corrosion from salt continues after drying, so a device that seems fine is on a timer
- The IP rating describes a new device in fresh water at a stated depth, which is a margin against accidents rather than a permission
- A device that survives may fail weeks later as corrosion develops, so back it up and treat the water resistance as gone
