Cleaning inside of Laptop screen

[rich52x]

A friend who stayed over a few days ago after a night out appears to have... brought the contents of his stomach upon my Lenovo G585 laptop while he was using it. The keyboard is busted but that should be easy enough to replace. However after cleaning the surface, it's clear the underside of the screen is stained (see images below). How do you guys think i should i go about cleaning it? i've never messed with laptop screens before and im not entirely sure where to start or if i'll need any special cleaning fluids etc.

Thanks in advance!

Warm damp rag. See the manual for cleaning instructions

You can not clean under the glass/plastic. It is all glued together.

Is there a screen protector on there that can be peeled off?

Use IPA (IsoPropyl Alcohol / Lens Cleaning Wipes) to clean the part You can get iy.
