I haven’t yet, luckily. But, I worked for a cell phone provider and it was a constant customer service issue. I don’t know about other electronics, but with a phone you take it apart completely and hand pat everything dry that you can. Then you leave it open in a safe dry place for a few days. I would say we had a 95% success rate, saving phones. Sometimes, they just spend too much time in the water, and aren’t able to be saved. It’s a good thing to read up on before an accident happens, that way you know right what to do when it does.
