Not our normal type of post but the new HTC Desire Android smart phone has been so useful with it’s open source applications, fast speed and wifi that I couldn’t believe I’d just put the phone in my shirt pocket and leant over the toilet!
Panicking, I fished it out and messed about trying to shut it down, when I should have just whipped the back off and the battery out. I did manage to get the battery out pretty quickly but not before I’d seen the screen start to make weird colours and odd lines. The thought of buying a new phone at full price was too much so I pulled out a handy bottle of Isopropyl alcohol (IPA) we use for cleaning tape and video record and repro heads. This is 99% pure IPA, not cheaper ‘rubbing alcohol’ that is often 70% IPA with 30% water. You really don’t want to make your phone any worse!
When I’d calmed down a bit I checked the moisture pads that show if the phone’s had water contact. These had gone pink confirming the toilet dunking so no warranty repairs here! Having little to lose I removed the 4 small torx head screws and the two even smaller crossheads screws under the rear cover. Two of the Torx screws have ‘void’ stickers over them so again once you undo them you’ve lost your warranty!
Now the bottom cover over the USB connecter can come up as can the inner cover which will reveal the wifi / bluetooth aerials. I didn’t remove the screen but ‘carefully’ poured IPA all over the bits that smelt of wee!
99% pure IPA will evaporate very quickly but any residual moisture should go before you can think about putting the battery and other cards back in. Many online sources recommend uncooked rice to absorb moisture but purpose made desiccants are best. I used several silica gel sachets in a freezer bag with the disassembled phone and left this overnight.
Thankfully this all worked, the phone starts, the screen works it’s alive!
The key points when you have this kind of phone disaster are:
- Get the phone out of the water / wee
- Get the battery out as soon as possible
- Remove all the SIM / memory cards
- Shake or carefully pat dry as much liquid as you can
- Any liquid contaminant that isn’t pure water and contains sugars or salts must be cleaned off
- If you try IPA make sure it’s high purity 99% is best
Finally, we’re tape transfer specialists not phone repair specialists so I offer no guarantee with all this but it did work for me.
