I have to agree with Nick here.
A soggy phone or laptop needs more than just some sort of desiccation product (Rice or Silica gel). While in a humid environment these do help reducing the atmospheric moisture trapped in a case from condensing onto the gear being held. They don't have any way of wicking off the moisture trapped inside. I do believe these have been over sold as the cure-all across the board.
The only way I know to slow the progression of corrosion and shorting of components is by first removing (disconnecting) the batteries and then wiping off (shaking out) as much wetness out as you can and lastly keep the device as cool as you can (but not freezing) that way you slow the progression of the chemical reactions until you can effectively open the device to get all the moisture out and neutralize any corrosives (salts, sugars & acids) as quickly as you can.
Unless you had spilled distilled water drying the device via heat is a very big gamble!
As you are more likely to enhance the corrosiveness of what was spilled, and in the case of sugars or starches they will just harbor bacterias and molds which over time alter the chemistry into a corrosive material and can act as the carrier of any present salts creating a short (an ionic pathway which is conductive).
