Reply to spilled drink on new ddjsx!!!!

So some drunk person spilled a drink on my new ddjsx at a new years party. Controller started acting up massively so I unplugged it flopped it over and let it air out. Today I played with it and everything is working fine but some of the buttons are rather sticky, they dont click like they used to. I'm not comfortable opening the controller up so I'm wondering if there is something I can spray to clean it?
