Rice to the rescue
If you're like me and have kids, you feel you're like a broke record and repeat certain phrases countless times through a day. One such is be carefull with food and drinks around gadgets and not allowed to bring them into the rest room
Still, once in a while there's an accident and if you act fast, there's a chance to save the gadget. Unless your kids decided to take the tablet into the bathtub, then it's most likely long gone...
Most modern devices (especially cellphones and tablets), are designed not to be taken apart without special equipment. So should the accident happen, turn of your device as soon as you notice. Take it a part as far as feasible (and you feel safe to reassemble it later). Put it in rice and leave it. Minimum a few hours, ideally a day or two. Exact time, will depend on how wet the gadget got and how deep the water penetrated into the device
I've lost count on how many devices I've saved this way
