How to repair cell phones, smartphone, remote controls or other after a bath in water

Today I read a post by a good photographer of my areas that had to change the 5d mark II due to a dip in the salt water.

I'm very curious to read his review on the canon 6d because it is my dream as soon as possible I want to buy.
During my work experience I have worked with electronic items like remote controls, mobile phones or other fallen into the water.
Logically, the worst situation is that with the water of the sea because its salinity makes it very conductive and then creates short circuits within the electronic boards. The current in normal situations should move in certain ways, putting the circuit in salt water these routes are no longer valid and current look for the quickest way to switch from positive to negative of our battery, if found we have a short circuit and all devices that are affected may be damaged.
For this reason, the most immediate thing to do is remove the battery, without trying to turn off the device or otherwise. We have to be very fast because it will create less damage. If you have an iphone that has the built-in battery that can not be removed do not have much hope.
At this point we can only hope that, if we were fast there are good chances that the current has not yet managed to do damage to any component of the PCB.
Unfortunately, once the salt water evaporates leaving the salt within our devices and this, in the presence of moisture, acts as conductor so we have to remove all residues.
To do this we attempt to disassemble, the ideal would be able to get to have the individual printed circuit boards separated from each other and immerse them in a bath of distilled water. I remind you that distilled water does not conduct current and is greedy of salts. The bathroom, depending on the conditions, may be repeated two or three times changing the water. When you see that the circuit has no more traces of salt can finish washing.
At this point, the theory says that it is enough to dry the circuits, but I do to make sure that the water has been completely eliminated I still do a one-hour bath in alcohol. This is water-repellent, it also makes a nice PCB cleaning and is also much easier to dry than water.
After bathing in alcohol you just have to dry it with a hair dryer or an oven and hope our device. Careful you are heading to the temperature, do not let electronic devices to reach more than 60-70 ° C
Unfortunately the hopes of reviving a mobile phone or another fell in seawater are very low, but attempt not cost anything.
