Mechanical keys random double/triple tapping. "Migrating" around keyboard. Fixable?

A couple months ago, I spilt coffee near my spacebar. I had it dried and cleaned it with some isopropyl alcohol and for a while, it seemed to work fine.

However, Z,X,C,V would randomly spam out extra letters
i.e. typing "zxcv" might look like "zxxccvcv".

Currently though, Z,X,C,V work perfectly fine and now A, S, and keys from the numberpad have the problem.

Odd thing is LEDs for for all problematic keys have always worked fine.

1. Is this more likely a mechanical issue or circuitry issue?

2. Is it ok to dunk the circuit board in an alcohol bath and shake it up a bit? (or what could I do that might help fix whatever the issue is?)

I would say a mechanical issue whereby the switches are being bogged down due tot eh coffee(dried, sticky sugar if you have sugar in your coffee). You will need to physically access the switch area and the switch to see if there is any residue. Outside of that, what is the make and model of your keyboard?

You're lucky the coffee spill didn't short and shutdown your computer for good.

Here's something as food for thought:
