I've seen an IBM field service tech clean an 1311 pack once (after the drive blew a gasket and sprayed hydraulic fluid everywhere). He used Kimwipes soaked in isopropyl alcohol. Since this was in college, I went to the chemistry department to get high purity (reagent grade) isopropyl alcohol for this job.
A solvent sounds good, but I would avoid "burning spirit" or rubbing alcohol or other grocery store stuff since it probably has all manner of contaminants in it, some of which may leave crud on the surface.
