I spilled milk on my laptop keyboard?

I have a Lenovo ideapad 100-15ibd, and I spilled milk on the right side of my laptop keyboard. The keyboard worked fine and like two hours later, some keys won't work. The list of keys are:

Spacebar
B
N
3 ( Numpad)
Backspace
Enter
RShift
Down arrow key
Left arrow key
Right arrow key
/
.
,
Touchpad

I left it overnight hoping it would dry, but I got the same results.
I used a card then proceeded to put it on the touchpad where some milk has become "plastic".
The touchpad was fixed but the other keys won't.
I have no idea how to detach the keyboard from the laptop since I just bought it.
I'm scared that my laptop won't work after a few days, weeks, how do I fix this?
If I'm missing any information, please ask me.

You should have cleaned the milk out before it dried. Just take out the battery and wash it with clean water, then leave it somewhere to dry out completely before you put the battery back. It's a bit late now the milk is dry, so you would need to take it all apart and clear it out. Or just buy a new laptop if that's easier, then be more careful with drinks around it
