We moved into this house two months ago, and it's become obvious that the enamel at the bottom of the bath has been worn away. I can clean the parts of the bath that aren't worn with cif, but the worn sections just rip up any clothes or sponges I try and use on them, and trying to soak them hasn't had much effect. There are already a few marks that just won't shift.
We can't get a new bath as it is a rented house so would probably have to replace it with another enamel one and we don't have the money for this. We've only got one bathroom, so we can't avoid using it either.
