Bad Diaper Rash. What do i do?

My poor boy has a really bad diaper rash. I think its because he had too much food with acid. (a lot of oranges) in them while staying with his Grandparents.Right now I am letting it air out by having him run around with no diaper. Any other suggestions? He doesn't usually get rashes much.
