Hello,

I have a old asus k52ju with maybe 6+ years.
Yesterday I accidentaly spilled a very small ammount of milk over it.
I dried it with some paper, and took the keyboard out. I noticed it was completely dry.
However some of the keys in the zone where the milk was spilled started pressing 2 characters at once, and sometimes the keyboard starts inserting characters alone.

What is wrong? Can I repair it somehow?
