My lovely polished granite worktops are getting marked with limescale round the taps. How do I get rid of this? The stone mason said no citric acid, and Viakal says not for natural stone. These are my two trusty standbys. Stone mason gave us some (probably very expensive) French spray, which looks like water, and might as well be for all the good it does.
I had no idea granite was so temperamental. Apparently no olive oil must ever touch it either.
