Is there any realistic way of "rejuvinating" the enamel of a toilet?


I threw the pan from the house my son bought last autumn because we were
unable to remove heavy staining and limescale from the bottom of the trap.
It laid among a load of other detritus pending a trip to the tip with the
trailer right through the winter. When I did get around to dumping it, it
was clean!
It seems the winter frosts had dislodged whole sheets of limescale and other
muck.
