Alienware M11x R2 Keyboard sticking how to fix?

I accidentally spilled a drink on my keyboard and now a good portion of the keys are sticking and just dont feel right when I click them, its rather annoying (although they still work) I tried taking off the keys and wiping them down a little with windex... it helped a little but didnt solve the problem. I feel there is a better way to completely fix the stickiness but I'm not sure how. Please help I don't want to spend the 61 dollars they want for a brand new keyboard.
