Keyboard spill! :D

Long story short: I spilled milk on my keyboard yesterday. It was working just fine. Today few keys are completely fucked up. My keyboard has no screws. So I decided to just put it in the water :D\

I did some reading and I found out that it is actually stuff that is left after the water is dried out that causes the keyboard to go fucked up. Do I have any hopes of fixing my keyboard by just leaving it in the water and drying it after wards?
