LOL- well make sure it is unplugged from the computer first-LOL

Just run it under the tap, warm water not hot - upside down, sideways etc.
then give it a good shake and /or let it drain upside down on a towel
over nite or so
then finish drying it with a blow dryer on medium, if needed

when you are sure it's all dry plug it in and test it.

what have you got to lose ?
either it will work or not.

we have even taken some of ours apart carefully and fixed minor problems inside of them.

some have a rubbery soft pad inside and some have more of a click mechanism- the rubber pad I think will take longer to dry all the way compared to the click mechanism ones.
