Fixing water damage in phone I dropped my phone into some water, immediately removed battery and soaked in rice (all I had at work). The phone dried, but the keyboard (G2) had some bad keys that have never corrected, and there seems to be some kind of residue on the screen, and the backlight is not uniform across the whole thing.

This all happened 2 months ago, but I would like to fix it.

Question is:

Do you think I could soak the phone in alcohol, and then dry it in an airtight container with Damp-Rid or silica gel or something similar to help fix the existing problems?

Some people seem to think this would cause more damage, I would love to hear the reasoning why though, as alcohol evaps clean...
How I remove consequences of water damage?


Disassemble device. You need to disconnect every power supply such as batteries.
Carefully look on every component.
Wash plastic details with cleaning agent likes 'Fairy', 'Mr.Muscul' and so on in water. Dry them.
Wash PCB in water as plastic details before. I use toothbrush. You need to take off any sign of corrosion. Then I wash PCB in isopropyl alcohol. After that I take air pump and blow compressed air on every electrical component on PCB. In such way I remove water. Then it is good idea to give ability PCB to become dry by natural conditions. If there are some troubles with traces on board, I repair them with special soldering equipment (beginning from common soldering iron and ending with BGA soldering station because ICs on PCB is soldered by such way)
Assemble device.


If you have troubles with your LCD, the only quality way is to replace it entirely. LCD is a set of number of transparent films. So it is very difficult to reassemble it without issues.
