Disassemble the laptop; the bottom panel should come off pretty easily given my experience with Lenovo Ideapad. I’d probably just replace the whole keyboard.
Bruh, any professional that even decides to touch it is gonna charge you a fortune for handling biohazard.
Why though? It’s RGB backlit now.
Why do I smell this picture?
I would just replace the keyboard. If you aren’t careful with rubbing alcohol, you’ll ruin the keyboard. Vomit + cleaning attempts ruined my ThinkPad.
Hey, we got the same laptop, high five bro 
.
I would take it apart as far as you can, then drown the whole thing (including the whole board and electronics) in isopropyl alcohol, then let it dry for about seven days just to be safe, and then turn it back on.
It does give a cool apocalyptic effect, pretty similar to The Last of Us. I may have to try this customization idea🌱.
Just hose it down.
Don’t get drunk on your laptop; simple fix.
Disassemble.
That party must have been wild; invite me next time.
You need to bin that laptop off, mate.
Rancid pong whenever you open the lid… 
Try electrical contact spray; lots of it.
If you drink a LOT of water, you can dilute the puke by puking on it again.
Sick custom upgrade.
Hahahaha yuck bro, gg.
Buy an ultrasonic cleaner or a new keyboard.
The best thing to do is get the entire palm rest keyboard replaced. There is no way you are going to get it cleaned. It needs to be replaced.
Dude, set that thing on fire and move on. Imagine your crush asks to use your laptop, and you force her to look, touch, and smell your RGBarf.
