Spilled small amount of water on MacBook Pro
So today I spilled a tiny (less than a tablespoon) of water on my MacBook Pros keyboard. I immediately dried all the water with a paper towel and then powered off and went between the keys with a qtip. I put it in rice for a few minutes before I figured why bother(the rice was getting in crevices so I sprayed some dust destroyer on the keyboard to get rid of the rice and dampness), and now it's flipped over on a cotton towel. My bedroom is air conditioned and the air is blowing towards the laptop. I heard humidity is a no no so I'll keep my room cold until I'm told differently. My question, however, is how long should I let it lay upside down (I picked it up just now [30 min upside down] and checked the towel for any moisture and there was none. I shook it out once more, flipped the towel and laid it down [keyboard down]). Also, are there any preventative measures I can take to make sure I'm not screwed (or have I already made a mistake?). I read that rubbing alcohol helps with electronics but I don't want to take chances. Please reply!
And water damage is how my last laptop died so you think I woulda learned my lesson. Guess not...
