Water damage at a glance
A phone in the sink, a tablet under a spilled coffee, a laptop caught in the rain: liquid damage is one of the most common ways good devices stop working. The good news is that what you do in the first few minutes often matters more than anything else. The bad news is that the most popular home remedies can make things worse.
This guide walks you through the first ten minutes, the mistakes to avoid, how different liquids behave, what water-resistance ratings really mean, the hidden signs of damage that show up days later, how to protect your data and what a proper water damage repair involves. It covers phones, tablets and laptops, because each needs slightly different first aid.
The short version: get it out, switch it off, don't charge it, don't heat it, don't put it in rice. Dry the outside, let it air out with the ports facing down, and get it looked at if anything seems off.
The first ten minutes: step by step
Liquid on its own rarely kills a device instantly. The real enemy is electricity flowing through wet circuits, which causes short circuits and speeds up corrosion. Your first job is to cut the power and stop more liquid getting in.
Phones
- Get it out fast. Every second of immersion lets more liquid past the seals.
- Unplug it if it was charging. Unplug the cable from the wall first, then from the phone, with dry hands.
- Power it off. Don't keep checking messages or pressing buttons to see if it works.
- Remove the case and any wallet or pop grip. Cases trap moisture against the body.
- Take out the SIM tray if your phone has one, using the proper ejector tool, and leave the slot open.
- Dry the outside with a soft, lint-free cloth. Don't push anything into the ports or speaker grilles.
- Tap gently with the charging port facing down to let trapped liquid drain out.
- Leave it to air-dry in a dry spot with some airflow, ports facing down. A fan blowing room-temperature air nearby is fine; heat is not.
Tablets and iPads
Treat a tablet the same way as a phone: power off, remove the case and keyboard cover, wipe it dry and stand it with the charging port facing down. Tablets have large, thin screens and big batteries, so liquid can spread under the display quickly. Don't charge it to test whether it still works.
Laptops
- Unplug the charger and hold the power button until it shuts down. Don't wait to save your work.
- Disconnect everything: USB drives, mice, docks and cables.
- If the battery is removable, take it out. Most modern laptops have an internal battery, so leave those closed.
- Open the lid wide and turn it upside down in a tent shape so liquid drains away from the keyboard and motherboard.
- Wipe up what you can from the keyboard and surfaces, then leave it alone.
Laptops are the device most worth getting checked even if they seem fine, because liquid can sit under the keyboard and reach the board slowly. Our computer repair page explains the kinds of laptop work we take on.
What not to do (and why)
When a device gets wet, the instinct is to do something, anything, to dry it faster. Most of the classic tricks either do nothing useful or cause new damage.
- Don't put it in rice. Rice doesn't pull water out of sealed electronics, and starch and dust can get into ports. Phone makers now advise against it. We explain more in the wet phone rice myth.
- Don't use heat. Hair dryers, ovens, radiators, heaters and sunny windowsills can warp adhesives, damage screens and stress the battery. Heat also pushes moisture deeper rather than drawing it out.
- Don't charge it. Charging sends current through wet components, which is exactly how short circuits and port corrosion start. Wait until it's thoroughly dry, and if your phone shows a liquid warning in the port, respect it.
- Don't use compressed air. A blast of air can push water further inside instead of out.
- Don't poke the ports. Cotton swabs, paper towel and anything metal can leave fibres behind or damage the pins.
- Don't shake it hard. A gentle tap with the port facing down helps drainage; vigorous shaking spreads liquid around inside.
- Don't open it yourself. Modern phones are glued shut and the battery sits right under the glass. Prying it open risks puncturing the battery, which is a fire hazard.
- Don't keep testing it. Turning it on every half hour to check gives electricity more chances to do harm.
Not all liquids are equal
What your device fell into changes the risk. Clean fresh water is the most forgiving. Anything with salt, sugar or chemicals leaves residue behind after the water evaporates, and that residue is what keeps corroding the circuits.
| Liquid | Main risk | What to do |
|---|---|---|
| Fresh tap water, rain, snow | Short circuits while powered on; slow corrosion if moisture stays inside | Power off, dry the outside, air-dry ports down. Get it checked if symptoms appear. |
| Pool or hot tub water | Chlorine and other chemicals leave residue and attack metal contacts | Power off and dry. For an intact water-resistant phone, a brief rinse in clean tap water can remove chemicals before drying. |
| Salt water (ocean, salted road slush) | Salt is highly corrosive and conductive; damage can keep spreading after it dries | Power off and get it seen soon. Salt residue usually needs professional cleaning. |
| Coffee, juice, pop, alcohol | Sugar and acids leave sticky, corrosive films; buttons and keys may stick | Power off and dry. Sugary spills on laptops and tablets are worth a professional clean. |
| Toilet or dirty water | Contaminants plus corrosion | Power off, wear gloves, disinfect only the outside with a lightly dampened cloth, then get it checked. |
About rinsing: phone makers suggest that a water-resistant phone splashed with something other than fresh water can be rinsed gently with clean tap water, then dried. Only do this if the phone is rated water-resistant and has no cracks in the glass. Never rinse a laptop, a cracked phone or an older device without a water-resistance rating.
Winter brings its own version of this problem in Ontario. Road slush is full of salt, so a phone dropped in a parking lot puddle in February deserves the same caution as one dropped in the ocean.
Water resistance and IP ratings explained
Most recent flagship phones carry an IP (Ingress Protection) rating, usually IP67 or IP68. The rating has two digits:
- The first digit (6) means the device is dust-tight.
- The second digit is about water. A 7 means it passed a test of immersion up to one metre for up to 30 minutes. An 8 means it passed a tougher test set by the manufacturer, usually deeper water for a similar length of time.
What the rating doesn't tell you
- It's tested in fresh water in a lab. Salt water, pool chemicals, soap and sugary drinks aren't part of the test.
- It's not permanent. The adhesive seals that keep water out wear down with age, heat, drops and everyday use.
- Any repair that opens the phone affects the seal. A good technician replaces the adhesive, but treat any opened phone as less water-resistant than when it was new.
- Pressure matters. Jumping into a pool, water-skiing or holding a phone under a strong tap puts more pressure on seals than sitting still in water.
- Cracks break the seal. A cracked screen or cracked back glass lets water straight in, whatever the rating says.
Tablets and laptops generally have little or no water resistance, so treat any spill on them as serious. Water resistance is a safety net for accidents, not a feature to rely on.
Signs of hidden water damage
A device can seem fine right after it gets wet and start misbehaving days or weeks later as corrosion builds. Watch for these warning signs:
- Fog or droplets inside the camera lens
- Muffled or crackly speakers, or callers who can't hear you clearly
- Spots, lines, discoloured patches or flickering on the screen
- Charging that stops and starts, or a liquid or moisture warning when you plug in
- Battery draining much faster than before, or the device getting warm while idle
- Random restarts, freezing or buttons that stop responding
- Face recognition, fingerprint or touch problems that weren't there before
- Green, white or crusty residue around the charging port or SIM tray
Many phones also have small liquid contact indicators inside, often visible in or near the SIM slot, which change colour when they've been exposed to liquid. A technician can check these as part of an inspection.
Some symptoms point to specific parts. Charging trouble often means a corroded port, which our charging port repair covers. A foggy or blurry camera after a dunk may need camera repair. Rapid drain or swelling after liquid exposure is a battery concern, and our phone battery guide explains the warning signs.
Safety first: if a device is swelling, hissing, smoking or hot to the touch after getting wet, don't charge it or press on it. Move it onto a non-flammable surface away from anything that can burn, and get help.
Rescuing your photos and data
For most people, the phone itself is replaceable but the photos aren't. A few steps improve your chances of keeping your data:
- Check your backups from another device. Before you worry, log in to your iCloud or Google account on a computer or another phone and see what's already backed up: photos, contacts, messages and notes.
- Don't factory reset the wet device. Resetting wipes the data you're trying to save.
- Resist the urge to power it on. If a backup is missing, the safest path is to dry it and have it inspected before it runs again.
- Tell the technician data matters most. If the goal is getting your photos off rather than fixing the phone long-term, say so. It can change the approach.
- Set up automatic backups afterwards so the next accident is only an inconvenience.

What a water damage repair involves
Water damage isn't a single part swap like a screen. It's closer to a diagnosis and cleanup. Here's what a typical repair looks like:
- Assessment and quote. You describe what happened: the liquid, how long it was in, and whether it was on or charging. The technician gives you a free quote before any work starts, and explains that liquid damage can be unpredictable.
- Opening and disconnecting the battery. The device is carefully opened and the battery disconnected so nothing is powered while it's inspected.
- Inspection. The board, connectors, screen and port are checked for corrosion, residue and moisture.
- Cleaning. Corrosion and residue are cleaned from affected areas with a proper electronics cleaning solution and given time to dry fully.
- Part replacement if needed. Parts that failed, often a battery, charging port, camera or screen, can be replaced.
- Resealing and testing. The device is reassembled with fresh adhesive where applicable and tested with you: charging, calls, cameras, speakers and touch.
Liquid damage doesn't always have a happy ending. Sometimes a board is too far gone, and sometimes a device works again but needs a part replaced later as corrosion shows up. An honest technician will tell you the realistic odds before you commit.
Repair or replace?
If the phone is old, the damage is extensive or you'd been thinking about an upgrade anyway, a new device may make more sense. If the phone is recent, holds data you need, or the damage is limited to a port or battery, repair is often worth a quote. Our article on repair vs a new phone covers how to weigh the decision.
How to prevent the next spill
- Keep phones off the edge of sinks, tubs and kitchen counters.
- Use a waterproof pouch at the beach, the pool or the cottage dock.
- Keep drinks away from laptops, or use a lidded cup at your desk.
- Replace cracked screens and back glass promptly so water can't get in.
- Don't charge in the bathroom, and keep cables away from wet surfaces.
- Turn on automatic cloud backups for photos and contacts.
Kids' devices take a lot of spills. A sturdy case helps, and our iPad repair and tablet repair pages cover what can be done when one does get wet.

Frequently asked questions
Should I put my wet phone in rice?
No. Rice doesn't draw water out of a sealed phone, and starch and dust can get into the ports. Phone makers advise against it. Power the phone off, dry the outside, and let it air-dry in a dry spot with the charging port facing down.
How long should I wait before turning on a wet phone?
Give it as long as you can, ideally a full day for a phone that was submerged. If the phone shows a liquid warning when you plug it in, wait and try again later. If it was in salt water or a sugary drink, get it inspected rather than testing it.
Is my waterproof phone safe in the pool?
Not necessarily. IP ratings are tested in still fresh water in a lab, not chlorinated pools or salt water, and seals weaken with age and drops. A brief accidental dunk is usually survivable, but swimming or diving with your phone isn't recommended.
Can water damage show up days later?
Yes. Corrosion builds slowly, so a phone that seemed fine can develop charging trouble, screen spots, muffled speakers or fast battery drain days or weeks later. If you notice new problems after a spill, have it checked before corrosion spreads further.
Can you recover photos from a water-damaged phone?
Often, but not always. First check whether your photos are already in iCloud or Google Photos from another device. If not, don't reset the phone; have it dried and inspected so a technician can try to get it running long enough to save your data.
What should I do if I spill something on my laptop?
Unplug it, hold the power button to shut it down, disconnect accessories, and turn it upside down in a tent shape so liquid drains away from the keyboard. Don't turn it back on to test it. Sugary drinks especially should be cleaned out by a technician.
