What To Do In Case Of A Spill

I was coming home one night with a large Number 13 from Wendy's and upon taking the very last turn into my neighbourhood the extra massive Sweet Tea sitting in my upper cup holder tipped over and fell, spilling everywhere in front, but primarily on my radio dash. Since then, my radio has stopped working, and my buttons in front became difficult to push due to all the stickiness. Has anyone any suggestions on what to do in such a case - my primary concern is how to get the radio to work properly.

Thanks
