I know , it can be done , but people will be scared to do that unless you demonstrate it to them. Many a times some electronic gadget will get drowned in water , I tell the owner to take it out of water , take the battery out and dry it up for few days and viola it will work.
The other day my son’s memory stick got washed in the washing machine , I told him to let it dry out and viola it worked and he was happy.
