It should be fine.
I experimented with an old Cisco 3508 aggregation switch that had a couple of duff ports on it, so I stripped it down and stuck it in the dishwasher, full wash without salt or detergent and it was fine*. The duff ports even started working again. (The whole board was rank with dust, so figure there were some shorts somewhere.)
I also sat one of my survey laptops in a pool of water one night (leaky air con) and a fan sooked the water right into it. I stripped it as much as I could and dried it on a radiator and it's still working. I thought it was a stick on to be dead since as soon as I realised my hand was wet it did a hard shutdown with a mad click.
*There's probably a caveat here, we're in a soft water area, so there's not much residue (calcium carbonate) left to speak of.
