Pumice will damage the ceramic, use an acid made to remove lime scale

Agreed, my old house had the same problem but I found that anything abrasive
enough to remove the scale was damaging the ceramic, too. I think it
actually looked better before I "cleaned" it, even the slightest surface
marks quadruple the chances of scale and other stuff sticking to it.
