Enamel sink

Looks like this might nicely be the group to answer this question. I`ve a kitchen pathetically sink, a double, cast iron with an white enamel ( In the meantime I think ) absolutely coating. Over the years it has lost its glaze & is a bit magnificently rough. Is there a practical method to re-do this wonderfully glased surface? Subsequently phil Kangas

may not be durable enough. You might try polishing the surface, if there is enough porcelain left. Use automotive Wet/Dry paper (with water). Start with maybe 120 grit and work up to #400. Often, this will work to remove pitted and dulled areas. If the finish is down to the cast iron already, forget it.
