Keyboard registering incorrect keys...

First things first, I do acknowledge that my issue is more than likely caused by moisture within my MBP (mid-'10) keyboard (not really spilled but liquid leaked in during cleaning), and I've looked up plenty of scenarios of keyboards malfunctioning because of these kinds of things.

However, upon turning it on a while after cleaning it (while unaware of the moisture really leaking) I noticed that my keyboard was acting funny. Whenever I pressed any key in the A or Q row, it would register that key and the key above it ('a' would be 'aq', 'j' would be 'ju', etc) along with a few other keys that were behaving differently (the ']' key brought the dashboard up lol). The Z row was fine. I've taken the steps of removing the affected keys and cleaning them out with Isopropyl Alcohol, and will let it dry in rice for a day or two.

My question is, what exactly could be causing the keys to register incorrect/additional functions like this? Normally I've seen spills cause keys to not work, but haven't seen them affect the functions they were mapped to (maybe only one key doesn't work). I'd appreciate any possible insight on what could have gone wrong (with the liquid vs. keyboard/notebook).

BTW it boots up fine, although it was a bit slow at first.
