Hi Lonn, It is great to see you posting. I would think that either kerosene or mineral spirits should clean up the grease and dirt without affecting the paint. It should be tested first in an inconspicuous spot. Also, as with any solvent, it should be used with adequate ventilation and while wearing nitrile gloves.
