How to Clean Rust Off of Marble in a Shower
It is easy to spot a rust stain on marble. It shows up as a perfect circle under the shaving cream can or the striped image of a screw. The Marble Institute of America says that rust is one of the most difficult stains to remove. It offers the following instructions for removing or at least improving a rust stain. If scrubbing with one of the safe nonabrasive scrubbers has not removed your rust stain, don't resort to steel wool. Try this.
Mix liquid rust remover with diatomaceous earth to form a thick paste.
Wet the marble with distilled water.
Cover the stained area with a layer of the mixture one quarter to one half inch thick. Extend the mixture at least an inch beyond the stained area.
Cover this with plastic wrap and tape down the edges.
Allow to dry for one or two days.
Remove the stain-removing mixture, rinse with distilled water and dry with a soft cloth.
