I would NOT recommend cleaners with abrasives (e.g. pumice). Protection of decals is a must.
Windex, GoJo Hand cleaner (without pumice) and MASS (a cleaner made in LaGrange, IL and available at Ace hardware stores) are often mentioned. The Collins CCA and CRA web sites are also good for general cleaning recommendations.
John King's S-38 and S-36A restorations (with photos) may be of interest.http://www.schmitzhouse.com/Johns_Electronics_01.htm
