Small spill on keyboard and now the keys are sticking

I have a rca tablet with a detachable keyboard. I was eating a bowl of cereal while watching something and I spilled a few drops of milk on the keyboard. Now the keys are sticking and if I press a key it ends up pressing several keys around it.

I've given it a day to dry, cleaned in between the keys wit a wet wipe, blew into it, but no luck. I'm not sure if I can take the keyboard apart because I don't know much about this kinda thing and don't wanna risk it. I'm also unsure about washing it.

Any advice of what I can do to fix my keyboard?
