A few days ago, my cousin spilled his orange juice all over my keyboard. I drained all of the juice as much as possible and left it alone.

Now, a few of my keys are VERY sticky, my mouse pad won't click or move momentarily, and I can't switch tabs. Is there any way to fix this? Can I pop my keys out and clean it?

My laptop is a Compaq Presario CQ57

This is my mother's laptop, so I'm afraid to ruin this laptop for good. Help!?
