MacBook Liquid Spill: What to Do in the First 10 Minutes

A glass of water tips over, a coffee slides off the table, and suddenly your MacBook is wet. The next few minutes can make the difference between a cleaning job and a dead logic board. Here's exactly what to do after a MacBook liquid spill, what to avoid, and why "it still works" doesn't mean it's fine.

Minute 1: cut the power

Electricity plus liquid is what causes short circuits and corrosion. Act fast:

1. Unplug the charger from the MacBook immediately. If the outlet or cable area is wet, unplug from the wall first for your own safety.
2. Shut the Mac down. Don't bother saving files. If it doesn't shut down normally right away, press and hold the power button (or Touch ID button) for about 10 seconds until it turns off.
3. Disconnect everything: USB drives, hubs, displays and other accessories.

Minutes 2 to 5: drain and dry the outside

1. Tip out the liquid. Open the lid as wide as it safely goes and turn the MacBook upside down in a tent shape on a towel, keyboard facing down, so liquid can run out instead of deeper inside.
2. Blot, don't wipe. Use a lint-free cloth or paper towel to soak up visible liquid on the keyboard, case and screen. Wiping can spread it into more openings.
3. Don't shake it hard. Vigorous shaking can push liquid further across the logic board.

Minutes 5 to 10: avoid the common mistakes

• Don't turn it back on to "test" it. Powering up a wet board is the most common way a small spill becomes an expensive repair.
• Don't plug in the charger. The battery still powers circuits, and adding charger power increases the risk.
• Don't use a hair dryer or heater. Heat can damage components and doesn't remove residue.
• Don't put it in rice. Rice doesn't pull liquid out of a laptop and can leave dust and starch in the ports. Read more in does rice fix a wet MacBook?

Why waiting it out isn't enough

Plain water is bad enough, but coffee, tea, juice, beer and soda are worse. They contain sugars, acids and minerals that stay behind after the liquid evaporates. That residue keeps conducting electricity and slowly corrodes the tiny components on the logic board. This is why a MacBook can seem fine for a few days or weeks after a spill and then suddenly fail to turn on, lose keyboard keys, or stop charging.

Drying the outside doesn't reach liquid trapped under the keyboard, around chips and inside connectors. The only reliable way to stop corrosion is to open the MacBook, inspect the board, and clean the affected areas properly.

Signs the liquid reached the inside

• Keys that stick, repeat or don't work.
• Trackpad that won't click or responds erratically.
• Screen lines, flickering or no picture.
• Not charging, random shutdowns, or not turning on at all.
• A sweet or burnt smell from the keyboard area.

If your Mac shows any of these, keep it off and get it checked. If it won't start at all, don't keep pressing the power button. See our guide on a MacBook that won't turn on to understand what's going on.
