I spilled milk on my laptop

Hi im 13 and i spilled milk on my laptop like 30 minutes ago i ran quickly to my sisters room and grabbed the only tissue i can find and wiped it , i turned it on and it seemed fine after awhile i kept trying to turn it off knowing its bad leaving it on and its not turning on and the screen has all these different types of colors i’m trying to disambel it like take everything out like screws etc. but i don’t have the right screw driver and i cant ask my parents to fix it because i just got my phone fixed yesterday and idk what to do help! fast!
