Acting in 60 minutes can save your device. Order what you need.
Spilled water, coffee, juice, or wine on your MacBook? The next 60 minutes are critical. This guide walks you through exactly what to do — and what NOT to do — to maximize the chance your MacBook survives.
Water damage kills MacBooks through two mechanisms: immediate short circuits (liquid bridges two conductors while power is on) and corrosion (residue from coffee, juice, or soda eats metal traces over days or weeks). Cutting power immediately stops the first. Proper drying prevents the second.
If the MacBook is still on, every second counts. Electricity + liquid = corrosion and blown components. Hold the power button for 5-10 seconds to force power off. Do not use the software shutdown menu — that takes too long and may trigger activity that spreads liquid through the logic board.
With lid open at roughly 90°, flip the MacBook so the keyboard faces down. This uses gravity to drain liquid out through the keyboard instead of letting it pool on the logic board beneath. Hold this position for 5-10 minutes, continuing to blot the exterior.
Use dry microfiber cloths or paper towels to absorb visible liquid from the keyboard, trackpad, ports, and display. Be gentle — you're blotting, not wiping. Don't use compressed air at this stage — it can push liquid deeper into the chassis.
Place the MacBook keyboard-side down in a tent (inverted V shape) on a dry surface. Leave it in a warm, dry area with good airflow. A room temperature of 65-75°F is ideal. Don't use a hair dryer — heat above 90°F can warp the display and damage battery cells. Don't use a microwave. Don't put it in rice (rice is ineffective and can introduce starch debris).
Place the MacBook in a large bag or box with multiple silica gel desiccant packets — the kind that come in shoe boxes, electronics packaging, etc. They actively absorb humidity from the air around the device. This is actually effective (unlike rice) because it lowers the relative humidity near the MacBook, accelerating evaporation from internal components.
The most common mistake is powering on "just to check" at 2-4 hours. The exterior may appear dry while internal components still have moisture trapped under chips, between board layers, and in connectors. Powering on prematurely with any residual moisture causes shorts that permanently destroy components that were otherwise fine. Wait the full 48 hours minimum — 72 hours for heavy spills or sugary liquids.
After the full drying period, connect the charger and press power. Watch for: normal startup chime and boot → good sign. Distorted display, flickering, no power, strange smells, or keys not working → stop immediately and seek professional service. Don't leave it unattended for the first 10 minutes of operation after liquid damage.
Work through: keyboard (every key), trackpad (click and gestures), display (all areas, no dead zones), speakers, microphone, camera, ports, Wi-Fi, and Bluetooth. Note any issues — liquid damage often causes subtle problems like one stuck key, intermittent port failure, or degraded battery capacity that appear days later as corrosion progresses.
If you spilled anything other than pure water, strongly consider professional logic board cleaning even if the MacBook appears functional. Technicians use 99% isopropyl alcohol and ultrasonic cleaners to remove corrosive residue before it destroys traces over weeks. MacBooks that "work fine" after a coffee spill frequently fail 2-6 weeks later as the corrosion completes its work.
Liquid damage repair cost depends on what was damaged: a keyboard-only spill caught immediately might need only a keyboard replacement ($150-250). A full logic board repair after an unchecked spill can run $400-800. Some damage is uneconomical to repair — a MacBook Pro M3 with a destroyed logic board costs more to repair than it's worth.
Get a diagnosis before committing to repair. Reputable shops offer free diagnostics or charge a small bench fee that applies toward the repair cost.
