One day I woke up and found my Nokia E61 dunked in a half-filled mug of sweet tea. (Oops.) Powered off and apparently dead. Liquid sloshing in the display compartment.
Took it out, immediately removed battery. Disassembled the case, removed the electronics, dried with toilet paper. Put battery in, powered on, it ran; backed up everything on sd card, powered off again. Disassembled as much as I could, washed parts in distilled water twice, then in isopropyl alcohol once, dried. Reassembled, and the thing worked, except the speaker; so handsfree use it was until the spare part arrived.
The phone worked until it was replaced with an E71, and the only reminder was a spotty pattern on the display backlight diffuser that was visible from an angle.
