I knew it was only a matter of time before I did the same to the SP3. And sure enough that's exactly what happened. I panicked for a brief second, then immediately detached the keyboard. Once this was done, I knew I could methodically start wiping the screen of the SP3 and wipe off the keyboard and bang it against the table to get the coffee out from between and beneath the keys. Now I just wait for it to dry.
Here's photo of the mess before I cleaned up the SP3 but after I cleaned up the keyboard.
