My wife spilled some coke on the buttons right by the cup holder and now the buttons stick. Is there any way to clean underneath them or would I be better off taking the car to get detailed at a shop?

 

you could try contact cleaner. if your not familiar, they carry it at most car places. its just basically spray carb cleaner thats ok to use on electrical equipment. just spray a bunch in there and click the button a bunch (make sure to do it with the car off to stop any possibility of a short circuit). if that dont work, the hell with it.
