How do i get the smell of stale beer out of plywood?

I have lived in and partied in a loft now for a while. The walls and floors are all plywood. But like the irresponsible young adult that i am i usually was too drunk to care when someone spilled something and too hung over in the morning to do anything about it then. so more and more beer was spill and not much was done about it other than just sopping it up with a rag and letting the rest soak in. But now it's time for me to move out and i want to get the smell of stale beer out of here for the next person. Help?
