Your heart sinks the second it happens. That slow-motion splash of a glass tipped over, the liquid spreading across the keyboard like a silent, conductive virus. You’ve probably heard a dozen different pieces of advice about what to do next. Most of it is actually terrible. Honestly, if you reached for a bag of rice the second you saw the puddle, you might have just signed your device’s death warrant.
Spilling water on a laptop isn’t an automatic game over, but the first sixty seconds dictate whether you’re buying a new machine or just dealing with a stressful afternoon. Electricity and water don't get along. We know this. But it’s not the water itself that usually kills the logic board—it’s the corrosion and the short circuits that happen while the power is still flowing.
Shut it down now (and no, I don't mean 'Sleep' mode)
Speed is everything. Don't worry about saving your document. Don't worry about "properly" exiting your apps. If you've just dealt with spilling water on a laptop, hold that power button down until the screen goes black. Every millisecond the battery is sending a charge through those wet circuits, you risk a permanent short.
Pull the charging cable out immediately. If you have an older laptop with a removable battery, pop it out. Most modern MacBooks and Ultrabooks have sealed batteries, which makes this trickier, but the hard shutdown is your primary defense.
Why the rice trick is a total myth
Let's address the grain in the room. Putting a wet laptop in rice does almost nothing. In fact, it's often worse than doing nothing at all. Rice is a "desiccant," sure, but it’s a weak one. It can’t pull moisture out from deep inside the chassis through tiny keyboard gaps. What it can do is get small grains of rice dust and starch stuck in your cooling fans and ports.
Real repair pros like Louis Rossmann have shouted this from the rooftops for years. Rice creates a false sense of security. You think, "Okay, it's in the rice, it’s being fixed," so you wait 24 hours while the water sits on the motherboard, slowly eating away at the copper traces. Use silica gel packets if you have them, but even then, airflow is a much better friend than a bowl of Uncle Ben’s.
The flip and the dry
Once the power is killed, flip the laptop over. You want it in a "tent" position—keyboard facing down, screen and base forming a V-shape. This uses gravity to pull the liquid away from the motherboard and back out through the keys.
Grab a lint-free cloth. Wipe up any standing water you see on the surface. Don't use a hairdryer on the "high heat" setting. You’ll literally melt your keycaps or warp the internal plastic components. A fan? Yes. A hairdryer on a cool setting? Maybe. But high heat is a disaster waiting to happen.

The chemistry of the spill: It's not just water
What you spilled matters more than how much you spilled. Plain tap water or distilled water is the "best case" scenario. It’s not great, but it’s manageable.
If you spilled coffee with sugar, or a soda, or orange juice? You're in trouble. These liquids are acidic and leave behind a sticky, conductive residue once the water evaporates. Even if the laptop dries out and turns on, that sugar and acid will continue to corrode the internal components over the next few weeks. You might think you've dodged a bullet, only for the laptop to die randomly three weeks later because a tiny solder joint finally dissolved.
- Black Coffee/Tea: Mildly acidic, leaves some residue.
- Soda/Juice: Highly corrosive and sticky. This usually requires a professional teardown.
- Beer/Wine: Very high sugar content and acidity. Dangerous.
- Saltwater: This is the end. Saltwater is incredibly conductive and corrosive. If you spilled a margarita on your laptop at the beach, the chances of survival are slim without an immediate professional ultrasonic cleaning.
Deep cleaning and the 99% alcohol trick
If you’re feeling brave and have a screwdriver set (like an iFixit kit), the best move is to open the back panel. Disconnect the battery connector from the motherboard. This is the only way to truly stop the "phantom" power from causing damage.

If you see visible residue or corrosion (it looks like green or white fuzz), you need 99% Isopropyl Alcohol. Don't use the 70% stuff from the grocery store—it has too much water in it. 99% alcohol evaporates almost instantly and is safe for electronics. You can use a soft-bristled toothbrush to very gently scrub away any sticky spots on the motherboard.
When to call in the professionals
There is a limit to what you can do at your kitchen table. If the laptop won't turn on after 48 hours of drying, or if the screen has weird splotches (water trapped in the backlight layers), you need a repair shop.
Look for a shop that specifically mentions "component-level repair" or "ultrasonic cleaning." Most big-box retail "Geek" squads will just tell you the motherboard needs to be replaced, which usually costs more than a new laptop. An independent specialist can often clean the board in an ultrasonic bath and replace specific blown chips for a fraction of that price.

Does AppleCare+ or insurance cover this?
Standard warranties almost never cover liquid damage. They have "LCI" (Liquid Contact Indicators) inside the chassis—little stickers that turn red when they get wet. You can't hide it. However, if you have AppleCare+ or a specific "accidental damage" rider on your renter's or homeowner's insurance, you might be covered for a replacement. It's always worth checking your policy before you drop $1,500 on a new machine.
The 48-hour rule
The biggest mistake people make after spilling water on a laptop is trying to turn it on too soon. You feel impatient. You have a deadline. You think, "It looks dry," and you press the power button.
Pop. That’s the sound of a remaining droplet of water bridging two pins on a high-voltage chip. Wait at least 48 hours. Put the laptop in a dry area with plenty of airflow. If you have a dehumidifier, run it in the same room. Patience is literally the difference between a working computer and a very expensive paperweight.
Practical steps to take right now
- Force Shutdown: Hold the power button for 10 seconds until it’s dead.
- Unplug Everything: Chargers, mice, USB drives—get them out.
- The Tent Position: Flip it over onto a towel to let gravity do the work.
- Assess the Liquid: If it was sugary or salty, start looking for a repair professional immediately. If it was plain water, you have a better shot at a DIY recovery.
- Remove the Bottom Plate: If you have the tools, open it up and disconnect the battery. This is the single most effective way to prevent permanent motherboard death.
- Dry and Wait: Leave it for two full days. Resist the urge to "test" it early.
- Check the Keyboard: Sometimes the laptop survives but the keyboard is "ghosting" or some keys don't work. You can usually plug in an external USB keyboard to get your data off before deciding on a permanent repair.
The reality of spilling water on a laptop is that it's a roll of the dice. But by killing the power instantly and avoiding the "rice trap," you've already doubled your odds of a successful recovery. Airflow and time are your only real allies here.
