New hope for water-damaged phones [telecom]

It's one thing removing the moisture from electronic circuit boards and components with heat etc., it's another to remove any residual muck left behind that can either cause corrosion or conductivity problems in the future.

If the process had the device dipped in a bath of circuit board cleaner I'd be more confident of it being a longer-term fix, but with the short lifespan of these devices it may not be an issue.

I once had a situation where a customer had a server sitting on the floor of a meeting room and it became unreliable after a couple of years, it turned out that the motherboard had a slimy film on it caused by six-monthly carpet steam cleaning which was sucked into the always running server by its fans, a good clean of the motherboard by the appropriate product fixed it but there would still have been long-term corrosion problems.
