Wow that's great news, however keep in mind that the water was not distilled so it contained a lot of micro particles that put a 'film' inside on the circuit-board. You could still
get a short so every now and then test it and keep an eye on its performance. If the casing is easy to open I would spray (clean
) the entire circuit-board with a good contact cleaner that doesn't leave a residue behind.
