I got my a DJ amp here, that's been sitting in a bar for about a year. Its pretty smoked out, but the audio is still in great shape. I need some advice on cleaning it up. I got it open here and apart, but I'm not sure exactly how to do about it. There's static in the gain controls, and the thing wreaks of nicotine and fryer grease.

What should I use to clean it out and flush out the controls and input/outputs?
