MacBook spillage, dried, boots up fine, crashes because of keyboard

I spilt beer on my Macbook Pro (left side of the keyboard) the other night… after which the screen crashed into a scary array of bright neon colours… So I removed the battery and everything and had a USB fan pointed at the opened Macbook for 6 days.

Today, I put the battery back in and saw the white screen and the Apple logo and breathed an empty sigh of relief, moved my trackpad and the screen crashed, except less dramatically than previously. I then plugged a USB mouse in and was able to log in and recover some files. I tapped the space bar and the laptop screen crashed again. It seems like there’s some connection between the keyboard/trackpad and the screen…

Would an alcohol clean of the motherboard help matters here and, if not, what should be my next move?

Thanks in advance!

Letting liquids dry on a board is always a bad idea..in a perfectly pure unconductive liquid environment electronics would work without a problem as in air..electricity doesn’t need to breath, problems come from conductive stuff diluted in liquids, carrying electricity where it shouldn’t go. When one air dries liquids just increases concentration of unwanted filth. Here’s an excellent guide to help you getting your board clean:
