Yikes. It's too late for you, but for the next person who has a spill, DO NO USE A HAIR DRYER.
It is maybe the worst thing you can do. It blows the moisture deeper into the components and it will often find it's way beyond the keyboard and into the motherboard. If it does dry it, it leaves the most residue where you don't want it, as you saw, in the keys. Lastly, it can really heat up the internal components while forcing moisture into them.
Don't blow into the spill, Suck it out. The best plan of attack is to use the highest power Vacuum you have with a very small attachment nozzle to suck out as much of the spill as possible. It will get a lot of it out from between keys and keep the moisture from going deep and doing real damage. Then let it sit in a dry place for no less than 24 hours, with the lid open.
Better yet, as I tell my daughter (who killer my beloved 12" PB with coke and a hair dryer) Keep your drinks away from you computer.
Very good advice! Sticky coffee in the keys is one thing, but if you blew any of that anywhere that current is flowing, you are gonna have almost immediate corrosion. If it was my machine, I would take it to Apple, tell them exactly what happened and what I did to dry it out. If any of that got to any of the electrical components, it's only gonna get worse with time.
