To reassemble your device refer to the iPhone [[Family:iPhone|repair guides]] for your particular phone.
After repeated cleaning, this example phone needed connectors 1, 2, and 3 replaced on the logic board, a new LCD, and digitizer. Corrosion on the cable ends and connectors could not be adequately removed. All other functions worked and this iPhone is now back in working order. Good luck. Hopefully this guide demonstrates that liquid damage to your iPhone isn't always obvious or visible and that disassembly and cleaning may benefit some phones exposed to liquid.
