Stupidly I thought they would clean up well with a carborundum stone, but
soon realized that they were *glazed* and I have now made a right mess of a

the process of taking out.

I'd either ignore it or replace them along w/ the broken one. Outside
nobody's going to ever notice much anyway.

You could try polishing (a la finishing Corian, etc.) but imo it would
be much effort for little purpose.
