Seabear,
If you are talking about removing smudges from your audio equipment, then as NH said, a light solution of regular dish soap and a damp cloth is all that is required.

Sunlight soap was the most common detergent used in cleaning crude oil from seabird feathers during the 1989 Exxon Valdez oil spill just to give you some perspective. Any light base solution will dissolve oils but in the nice, non-caustic way.
