I spilled something on my laptop!?

I was baking and reading the recipe off of my laptop, when I knocked over the vanilla extract. A mild amount of it spilled onto my laptop, and I immediately wiped it off and wiped it off the keys. It worked fine for a few minutes, but now the E, T, U, I, O, Z, 1, 2, -, _ keys don't work. Help help help! It is a Toshiba Satellite L655.
