The most important step, and darn near impossible. Is to remove the battery immediately and refrain from turning it on until about 3 days later after it is really really dry (after the rice trick) Shorting the components out further is what you are trying to avoid. It is an impossible urge to fight so be warned. After three days if it is not working try the following.
Strip the device as much as possible and soak the components (except battery) in separate clean, soap residue free, dishes with distilled water then rinse with more distilled water. Let dry. If that doesnt work try it with isopropyl alcohol.
Its not the water, its the impurities in the water that cause a lingering short to the components.
