Anything electronic will work after being soaked if allowed to dry. Water DOES NOT conduct electricity, it is the minerals in the water that causes the sparks.
Best bet is to open it up and allow air to filter through the thing.
I would also have it checked by a professional repair shop or Canon.
The big issue is the sensor. Water spots can cause very big prob. if it got inside.
DO NOT turn it on. Pull the battery and let dry in a very DE-humid area.
The battery never got wet. I did turn it on though. It said can not operate due to error then shut down again. I dried it with a towell and blew it out with compressed air.
Uh-oh Compressed air?
I hope you never put that poison inside the camera...
also turning it on in the first place is a bad idea...
NEVER turn an eletrical item on if it has water inside / been in contact with water that can cause your camera / eletrical appliance to short circut...
You should instead remove all sources of power, (main switches e.g. wall plugs or batteries or anything else used to power the item)
that way you increase the chance of your items survival
uh and hair dryers dont work either... they burn out your circuts....
wet eletricals + heat = bad... real bad
the best way to treat water logged eletricals is, remove as much casing as possible, seperate the pieces as much as possible (without removing screws unless you know how to put it back together with no faults.)
and leave the rest to the air to dry off, this way it changes the temperature at a slow steady pase instead of jumping from cold to hot etc..
