water damage how do I fix it.

first of all -> i never did the rice thing <- it simply makes not much sense (in my opinion!)

non technical fluids (like water) shortens the parts on the logicboard and that will not go away if you put the device in rice.

so cleaning is the only solution i ever did (hundrets of times - i was in the "cell phone repair business" for years).

i use a special electronics cleaner - but you can use IPA (>90%) and a soft paintbrush to clean the shorted parts, easy to recognize - they are mostly white/grennish - something similar to mold. clean (carefully) all connectors - don't forget the dock connector (in- and outside)

let it dry, check everything again and if it's clean - reassemble everything and try to power on the device.

soetimes the battery is complete empty - measuring it is easy and saves a lot of trouble
