Keys sticking

So, I accidentally spilled Black Cherry Soda on my keyboard. Yeah, I know, it sucks.

Thankfully the damage only seems to be most the keyboard barely lights up anymore and the keys are sticky.

My question is should I just take it to the Apple Store and bite the bullet and pray the warranty will get it fixed, or can I pop the keys up like you can on a regular PC keyboard to clean it out.

If you try to clean it out yourself, you could possibly void the warranty. Maybe the soda does that anyway, but if it were me, I'd take it to the store and see if they'd fix it...
