Water and electronics have never been friends. One moment of bad luck — a phone slipping into a sink, a knocked-over glass landing squarely on your laptop keyboard — and suddenly you’re staring at a device that may or may not ever work again.
The good news? Water damage is not always a death sentence for your device. Whether it’s a smartphone, a laptop, or a tablet, what you do in the first few minutes after exposure makes an enormous difference to whether your device can be saved. What most people do instinctively — pressing buttons, shaking the device, reaching for the rice bag — is often exactly the wrong thing to do.
This guide will walk you through the right steps, explain what’s actually happening inside your device when it gets wet, and tell you honestly when it’s time to bring it in to a professional repair centre.
Why Water Damages Electronics — and Why Speed Matters
Before we get into what to do, it helps to understand what’s actually happening when your device gets wet.
Pure water, on its own, is not a great conductor of electricity. The real problem is that tap water, rainwater, lake water, and especially drinks like coffee, juice, or soda contain dissolved minerals, salts, and sugars — all of which conduct electricity extremely well. When this liquid makes contact with the live circuits inside your device, it creates unintended electrical pathways that cause short circuits, often within seconds.
Short circuits are destructive. They send current through parts of the board that aren’t designed to handle it, burning out components, corroding contacts, and leaving behind mineral deposits that continue to cause damage long after the device appears to have dried out.
This is why speed matters so much. The faster you act to cut power and get the device into the right conditions, the better your chances of recovery.
Water Damaged Phone — Step by Step
Step 1: Get it out of the water immediately
This sounds obvious, but people sometimes freeze. Every second your device spends submerged increases the volume of water that enters through speaker grilles, charging ports, SIM trays, and any microscopic gaps in the casing. Get it out now.
Step 2: Power it off — do not check if it still works
This is the single most important step, and the one most people skip. Resist every urge to press the home button, tap the screen, or try to see if it still works. Powering on a wet device is one of the fastest ways to cause permanent damage — you are essentially sending electricity through water-soaked circuits.
If the phone is already off, leave it off. If it’s on, power it down immediately. If the screen is unresponsive and you can’t shut it down normally, hold the power button until it forces off.
Step 3: Remove everything you can
Take out the SIM card and SIM tray immediately — these are common entry points for water and the tray pocket traps moisture. If your phone has a removable battery (less common on modern phones but still found on some models), remove it now. Do not attempt to charge it.
Wipe down the exterior with a dry cloth or tissue, paying attention to the charging port, headphone jack, speaker grilles, and the SIM tray slot.
Step 4: Do not put it in rice
The rice myth is perhaps the most persistent piece of bad advice in consumer electronics. Here is the reality: uncooked rice has very limited moisture-absorbing capacity, it introduces dust and starch particles into your device’s ports, and it gives you a false sense that you are doing something productive while time passes and corrosion sets in.
If you want to use a desiccant, silica gel packets — the small pouches found in shoe boxes and electronics packaging — are meaningfully more effective. Even better, move straight to Step 5.
Step 5: Position it correctly and allow airflow
Place the phone upright or at a slight angle so that gravity helps any pooled water find its way toward an exit point. Do not lay it flat. Place it somewhere with good airflow — in front of a gentle fan is ideal. Do not use a hairdryer, microwave, or place it in direct sunlight or on a hot surface. Heat accelerates corrosion and can warp internal components and melt adhesives.
Step 6: Leave it alone for at least 24 to 48 hours
If the water exposure was minor — a brief splash or a few seconds in shallow water — 24 hours of drying in good airflow may be sufficient before carefully attempting to power it on. For more significant exposure, 48 hours is safer.
Even after this period, be aware that mineral deposits from the water may remain on the circuit board and continue to cause problems days or weeks later.
Step 7: Bring it in for professional assessment
Even if your phone powers on and appears to work normally after drying, a professional inspection is strongly advisable. Water damage is insidious — devices can appear to function fine and then fail days later as corrosion progresses. A technician can open the device, inspect the board under magnification, and perform an ultrasonic cleaning that removes mineral deposits no amount of drying can address.
What If Your Phone Was Submerged for Longer — or in Salty, Sugary, or Dirty Water?
Standard water is bad enough. Saltwater, seawater, juice, coffee, tea, soda, and dirty water are significantly more damaging because of their high mineral and organic content. If your device was exposed to any of these, the chance of internal corrosion is much higher and the window for effective intervention is shorter.
In these cases, skip the home drying stage and go directly to a repair centre. The corrosive compounds in these liquids will continue reacting with your circuit board as long as they are present. Professional ultrasonic cleaning removes these deposits in a way that home methods simply cannot.
What About IP Ratings? My Phone Is Water Resistant
Many modern smartphones carry IP67 or IP68 ratings, which means they have been tested to withstand water immersion to a specified depth for a specified duration under laboratory conditions. This is a useful feature, but there are important caveats that manufacturers are not always forthcoming about.
IP ratings degrade over time. The seals and adhesives that make a phone water resistant wear down with normal use — drops, heat cycles, and simply opening the SIM tray all reduce the effectiveness of the seal. A phone that was IP68 rated when new may offer meaningfully less protection two years later.
IP ratings also do not cover all liquids. They are tested with fresh water. Saltwater, chlorinated pool water, and drinks will breach the seal more aggressively and cause more internal damage than fresh water, even on a rated device.
So yes, an IP-rated phone has better odds — but it is not immune, and you should still follow the steps above if your rated device gets wet.
Laptop Water Damage — Step by Step
Laptops present a different set of challenges. They have more surface area, more entry points, more complex internal components, and a battery that is both large and difficult to disconnect without opening the machine. Here is what to do.
Step 1: Cut power immediately
Do not hesitate. Hold the power button down until the laptop shuts off. Do not go through the normal shutdown process — just force it off. Every second it stays powered while wet increases the risk of a short circuit destroying the motherboard, RAM, SSD, or GPU.
If it is plugged into a charger, unplug the charger from the wall first, then from the laptop. Do not touch the laptop with wet hands while it is plugged in.
Step 2: Flip it upside down
This is the opposite of what you would normally do with a laptop, but it is correct. Flipping the laptop upside down — like an inverted V with the screen and keyboard forming the two sides — allows liquid to drain away from the motherboard, which sits beneath the keyboard. The keyboard itself acts as a buffer; the worst outcome is liquid pooling on the motherboard.
Open the screen to approximately 90 degrees and rest the laptop upside down on a clean, dry cloth.
Step 3: Remove external connections and peripherals
Disconnect the charger, USB devices, external monitors, and anything else connected to the ports. Liquid can travel along cables and into connected devices. Remove any SD cards or USB drives in the slots.
Step 4: Remove the battery if accessible
On older laptops with removable batteries, remove it immediately. On modern ultrabooks and MacBooks, the battery is internal and requires a screwdriver to access. If you are comfortable doing this safely and have the tools, doing so in the first few minutes dramatically reduces the risk of further damage. If not, do not attempt it — you risk causing additional damage and should instead proceed to professional repair as quickly as possible.
Step 5: Blot, do not rub
Using a dry cloth or paper towel, gently blot any visible liquid from the keyboard, trackpad, ports, and surfaces. Do not rub — rubbing spreads the liquid laterally and can push it further into the device. Pay particular attention to the keyboard, as the gaps between keycaps are a primary entry route.
Step 6: Do not use heat
The same rule applies as with phones. No hairdryers, no placing the laptop in sunlight, no leaving it on a radiator. Gentle airflow from a fan is ideal. Position the laptop so gravity continues to assist drainage.
Step 7: Wait, then get it professionally assessed
For laptops, the professional assessment is even more important than for phones. Laptops are more expensive, more complex, and the consequences of a delayed corrosion-related failure are more severe — especially if you have important work data on the machine.
Even if the laptop appears to power on normally after drying, bring it in. A technician can open it, inspect the board, clean the affected areas, and check that the battery has not been compromised — swollen or damaged laptop batteries are a fire risk.
What a Professional Water Damage Repair Actually Involves
When you bring a water-damaged device to a repair centre, here is what the process typically looks like at a professional level.
The device is opened and visually inspected for obvious corrosion, burn marks, or liquid residue. The battery is disconnected immediately if it has not been already. The affected boards and components are then cleaned — professional repair centres use an ultrasonic cleaner, which uses high-frequency sound waves in a cleaning solution to remove mineral deposits from every surface and gap of the circuit board, including areas that are physically impossible to reach manually.
After cleaning, the board is inspected under magnification. Any components that have been burned out or corroded beyond recovery are identified. Where components can be replaced — capacitors, charging ICs, power management chips — a skilled technician can perform component-level repairs. Where the damage is too extensive, an honest assessment will tell you what the realistic options are.
This is why professional cleaning is so much more effective than home drying. Home methods remove bulk moisture but leave behind the mineral and organic deposits that continue to corrode the board. Ultrasonic cleaning removes the deposits themselves.
Signs Your Device Has Hidden Water Damage
Sometimes water damage is not immediately apparent. Here are signs to watch for in the days and weeks after an incident, even if your device seemed to recover:
- The battery drains significantly faster than before
- The device randomly restarts or powers off
- Certain keys on a laptop keyboard stop responding or become sticky
- The charging port is unreliable or charges intermittently
- The screen develops spots, lines, or discolouration
- The camera lens fogs up from the inside
- The speakers sound distorted or muffled
- The device runs noticeably hotter than before
- Wi-Fi or mobile signal becomes weak or intermittent
Any of these symptoms after a water incident are a signal that corrosion is progressing internally. Do not wait for the device to fail completely — the sooner it is assessed and cleaned, the better the outcome.
When Is a Water-Damaged Device Beyond Repair?
Honestly, not every water-damaged device can be saved — and a reputable repair centre will tell you so upfront, at no charge for the assessment. Devices that have been submerged for extended periods, exposed to highly corrosive liquids like saltwater, or powered on repeatedly while wet have a lower chance of full recovery.
Even in these cases, data recovery may still be possible. If your device cannot be repaired but you have irreplaceable photos, messages, or documents on it, a professional can often recover data from the storage even when the device itself is no longer functional.
The Bottom Line
Water damage is a race against time and corrosion. The right actions in the first few minutes — powering off, removing accessories, allowing proper drainage, and avoiding heat — give your device the best possible chance of recovery. The wrong actions, particularly powering on a wet device or using heat to dry it, can turn a recoverable situation into a permanent loss.
When in doubt, get it to a professional quickly. The cost of a proper diagnostic and cleaning is almost always a fraction of the cost of replacing the device — and often the difference between recovering it and losing it entirely.
