water damage liquid damage

Is this a good question?
As you know water and electronics and electricity are not a good mix.
The water causes corrosion and provides circuit paths for the electricity which were not in the camera's operating design and could damage the components.
First do not turn on your camera and then you need to remove the battery as soon as possible from the camera to minimize further damage.''
Then you need to dis-assemble the rest of the camera and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% and is not as effective. If you do check the label to verify the amount
Here is a link that in general, describes the process.
You may have to replace the battery as it is very hard to recover a battery from water damage.
As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.
Hopefully after you have done all this the camera might possibly work correctly again.
Here is a link to the ifixit guide on how to replace the lens in your camera. It is useful because it shows how to open your camera so that you can access the components inside to clean them properly.
If this process seems too daunting, take your camera to a reputable, professional camera / electronics repair service and ask for a quote for a repair.
If you decide to do this, do it sooner than later.
