By now I figured out that I did everything I wasn't supposed to and that was stupid of me, but can anyone tell me how to fix it now, maybe open it and dry it or something else that works
There is a HUGE possibility that it is done for, but I know thats what you do not want to hear right now.
You said that
screen went completely white but you can see water droplets inside the screen. I tried the home button but it didn't work. it soon ran out of charge.
well
something has to be working to make the screen, so the logic board might not be destroyed
Instead, do this:
put it in a bowl/bag of rice or
set it out in a place where air ventilates (anywhere but a drawer, for example)
leave it like this for as long as possible.
because the screen blacked out/white screen, plan to buy a new one, so you wont be too disappointed if it still doesn't work.
If you have bought a new ipod, make sure to plug it in (and hope for the best) before you are unable to return the bought iPod (it case it works). But this should at least be a couple of months?? if not familiar with the warranty..
Finally, If you do want to tinker with it, which I love to do, (its fascinating inside) I found great use of iFixit.com, I'm not advertising, its just that their instructions are great. Just be VERY careful, and a small flathead screwdriver in the right place (next to or even at the metal clips holding on the screen) works way batter than the "ipod touch opening tool".
