Most modern kit is an absolute nightmare to take apart. Basically the manufacturers don't want you diving inside so make it as difficult as possible to get in without destroying the thing in the process.
But for something like liquid ingress, getting inside is the only real way to clean up the mess properly. Especially with things like tea, coffee and some fizzy drinks that can leave a nasty residue behind.
Plain water is the best beverage to use if you think your expensive toy is thirsty

If you leave it to dry out and offer up the correct incantations to the electronic gods plain water might just dry out without causing too much damage, if you can empty out as much of the liquid as possible.
But it can be in the lap of the gods whether it ever works properly again. I've seen kit that has suffered the most horrific abuse at the hands of it's users and yet still worked as good as when it was first taken out of the box. Other stuff I've seen go off in an electronic strop and refuse to work ever again just because you looked at it a bit funny
