Dell Latitude E7250 water damaged

My Dell Latitude E7250 has been water damaged. Water was being spilled on it for more than a week probably, when I found it, the water was only bottom cover deep but I have to assume it went through or at least around the entire laptop.

When I took the bottom cover off I found water was mostly everywhere.

I left it air drying for 24 hours but I’m still afraid to power it on. One thing that has me concerned is that i found what looks like rust?? on the RAM and wifi card. (Photos included)

Should I try to power it on or do something else?

Any help is greatly appreciated.
