You also might try toothpaste.
Plain ol' unadulterated toothpaste is a pretty decent cleaning/lapping compound in a pinch. I've bought a few of the trip-size tubes on sale at the drugstore or grocer for the workshop. I've found it to be a pretty handy common material for the hobbyist.
Just a thought.
