A Washington Post reporter who accidentally dropped his Blackberry in the toilet was able to retrieve it and dry it out to working order again: by leaving it turned off in a bowl of uncooked rice.
Rice quickly sucks up the surrounding moisture. Make sure the environment is free from excess humidity, drop the wet device in a container of rice and let it sit. For a better desiccant, it’d be a good idea to store all those little silica gel packets that come in anything from shoe boxes to moisture-sensitive gadgets.
