The issue with using abrasives to clean the points is that the embedded particles can cause the points to stick. If the points are flat, a very fine cut point file is OK, especially if there is evidence of burning - nothing to lose. If the points are rounded, as they are in voltage regulators, DELCO recommended only a spoon or riffler file (the type of file used by silversmiths) be used, since the flat file can't conform to the point shape. If some of the points look pretty good, and just need burnishing, then a file probably isn't needed, just some stiff card stock or something like that. Hope this helps!

I should add - I'm following this with interest, as I have been contemplating giving a go at restoring an original radio in my '53. Thanks!
