The real question is if the device was powered on. If its powered on you risk damage due to shorts.

Its actually part of the manufacturing process for PCBs to wash them with water.

Despite common belief, water does no damage to electronics if the electronics are not powered on.

the gme portable was off,the screen full of water, battery terminals rusted and antenna snapped off
the uniden was turned on and had a quick wash with fresh water
