Water-Damaged iPhone or MacBook: What To Do Immediately

Step 1: Power it off

The single most important step. Power flowing through a wet board causes shorts and accelerates corrosion. Hold the power button until the device shuts off completely. On a Mac, that's the power button held until it shuts down. On an iPhone or iPad, use the standard power-off slider or force a power-off if needed.

Step 2: Don't charge it

Plugging in a wet device is one of the fastest ways to turn a salvageable repair into an unsalvageable one. The charger pushes current through corroded paths, shorts out components that were merely wet, and damages the board further.

Step 3: Don't try to dry it with rice or a hair dryer

Rice doesn't pull water out of the inside of a sealed device — it just sits in the rice bag. Hair dryers and oven trays add heat that can damage components, warp the chassis, and reflow solder in places it shouldn't be. Stand the device in a tent or fold to drain residual liquid, but skip the home-remedy drying methods.

Step 4: Skip DIY board cleaning if data matters

Opening a wet device on a kitchen table to wipe it down sounds reasonable, but it's where a lot of liquid-damaged boards get further harmed — connectors snapped off, components bumped, electrostatic discharge into sensitive ICs. If the data on the device matters, please don't take the device apart yourself. Bring it (or ship it) to a microsoldering bench while the corrosion is still localized.

Step 5: Contact a microsoldering shop sooner rather than later

Time matters with liquid damage. Sugary drinks (juice, soda, coffee with milk and sugar) and salt water cause faster, deeper corrosion than plain water. Even with plain water, the longer the device sits, the more the residue inside the board oxidizes copper traces. We'd rather see the device the same day than next week.

Liquid damage board repair on a MacBook usually involves disassembly, ultrasonic cleaning of the board, microscope inspection for damaged pads or lifted components, and replacement of any failed parts. The same general approach applies to iPhone and iPad logic boards — see our dedicated MacBook logic board repair and iPhone & iPad logic board repair pages for the device-specific details.

What to expect at the bench

Realistic limits

Liquid damage is one of the harder repair categories because every spill is different. Some boards come back fully — the damage was localized, the corrosion was caught early, and a few components were replaced. Some boards are unrepairable — corrosion has progressed through internal layers of the PCB, or critical components have been damaged beyond replacement. We share an honest read after the diagnostic before any soldering work is approved.

Where to start

If the priority is the data on the device, start with our board-level data recovery page. If the priority is restoring the device, the MacBook logic board repair or iPhone & iPad logic board repair pages cover the workflow for each device family.
