I have used a limescale remover in my brother's new bathroom, rying to be helpful, and have damaged all the taps. The limescale remover called harpic 100% limescale remover seems to have striped the chrome plate leaving a mottling effect. Does anyone know anything that will be able to polish this out? The bath tap is a fountain type at the area of the bath that cannot be reached without causing enormous problems. The repair would need to be done in situ for this tap. The other can be replaced (at great expense) but the bath is a big problem. Help!
