Chosen Solution

I managed to take care of my old macbook really well over the years, but messed up and used a very wet clorox wipe, I quickly tried to wipe it off and it seemed fine. Closed the laptop, arrived hours later to find it hot to the touch. Opened it up, keyboard and track pad won’t work at all. Power button works, it charges fine, screen is fine and when I hook up an external keyboard and mouse it also works. But from the sounds of it, does it sound like the keyboard and trackpad needs to be changed, or is it some wire that connects both? So long as there’s no soldering, think I should be fine to do it myself (any tips on not blowing out the back light appreciated). Please and thank you. Edit: Also the fan is going at it pretty loudly.

In your Air model the keyboard cable goes through the trackpad, thus if you’re lucky, so to say, replacing the trackpad and connecting cable may do the trick. Unfortunately liquids have a nasty habit to get anywhere and a small drop can make a big mess anywhere randomly. However, unless you want to undertake a complete disassembly for inspection and cleaning of your Mac, trackpad replacement would be the first try and error reasonable step.
