Might be too late, but here's how to save an electronic device dropped in water:
- Remove the battery immediately, if possible, while still submerged.
- Do not let the device dry out immediately. This causes the deposit of mineral salts on the circuit bourds, leading to short circuits later.
- If submerged in salt water, place in fresh water for a fe minutes, to help dilute the salt content.
- Place device in a bath of methylated spirits or isopropyl alcohol.
- Remove after a few minutes and let it dry naturally.
Good luck!
