Title:

How do I clean corrosion after water damage?

Text:

I have an iPhone 4 that was immersed in water, but apparently worked for an hour or so before any problems were evident. It has spent two days in a bowl of rice, but I decided to open it up to see what's going on. The two water-sensitive stickers on the back of the logic board have turned pink, and there are copper salts deposited on the logic board near the bottom of the LCD connector (the connector outlined in orange at Step 17 here: [guide|3143|page=6]).

I'm thinking that I will try to clean up this corrosion before trying to plug it in again, but I'm not sure what sort of tool to use. Are we talking isopropyl alcohol and a Qtip, or is there some other accepted approach?
