Whether it is a spilled cup of coffee on your MacBook or an iPhone dropped in liquid, water damage is a race against time. The actions you take in the first 5 minutes dictate whether your device survives.
Emergency Steps to Take Immediately
Step 1: Disconnect from Power
Unplug the device from any wall charger or peripheral cable immediately.
Step 2: Do Not Attempt to Power It On
If the device turned off, leave it off. Do not try to turn it on to “check if it still works.” If the device is still on, power it down immediately.
Step 3: Skip the Rice, Get It Cleaned
Do not put the device in a bag of rice. Rice does not absorb water from deep inside the tightly packed chassis of an iPhone or MacBook; it only introduces starch and dust into your charging ports.
The Science of Corrosion (Why Power is the Enemy)
Water itself doesn’t actually break electronics—electricity does.
Tap water, rain, and beverages contain dissolved minerals and salts. When the electrical current from your device’s battery runs through that mineral-rich water, it triggers a chemical reaction called electrolysis. The electricity causes the basic metals on the logic board (copper, solder) to dissolve and bind with the minerals in the water.
This reaction leaves behind a conductive, crusty green/white corrosion that eats away at the microscopic traces on the motherboard, permanently shorting out components. By removing the power source, you stop the electrolysis in its tracks.
Instead, the device needs to be opened, the battery disconnected, and the board properly cleaned to remove the mineral deposits before they rot the metal traces. If you are in downtown Chicago, visit Arbor Mac immediately for professional board cleaning and liquid damage recovery.
