Everyone seems to be missing a step in wet electronics. I seem to always end up fixing my friend's various phones, cameras, remotes, etc. when they go into the lake, pool, ocean, or go through the washer. It takes more than just opening up and drying it. One thing to remember is that water by itself has no effect on DC current, and DC will work while submerged just fine. It's dissolved particulates that's the problem. When something gets wet, even in salt water, turn it off right away and remove the battery. At your earliest possible convenience, fully disassemble the device as much as you can without breaking it, and remembering how to put it back together. Rinse it under fresh water, using a toothbrush to gently scrub the internals. Use good judgment as some electronics have parts that should be handled very gently. Shake any loose water off, and let it air dry while disassembled for at least 24 hours. Upon inspection, if any part is still wet, let it dry longer. Once reassembled, it should work just fine. Using this method, I can usually save about 90% of electronics that went for a dunk and were then subsequently not working until they were cleaned and rinsed in fresh water.
