How to Remove Rust Stains From Marble

Updated February 21, 2017

Marble elements add an attractive and luxurious feel to any home or apartment. In more expensive homes, you may find marble floors, bathroom and kitchen counter tops, sculptures and marble-topped furniture. But because marble is also costly, taking regular care of it and cleaning it in the right way are important for long-lasting beauty. Like other objects, marble is prone to rusting and other stains. Using coasters and keeping rusty objects off the marble are the first lines of defence. But there are also ways to remove rust from marble once it forms.

Make a poultice in a glass container using rust remover and diatomaceous earth. Create a thick paste.

Wet the marble with distilled water using a sponge.

Apply the paste to the rust with a plastic or wooden spatula. Make the paste ¼ inch to ½ inch thick on the marble.

Tear off cling film and put it around the poultice to seal it in. Secure the edges of the cling film with tape.

Allow the poultice to dry on the marble for one to two days. The Marble Institute of America reports that the drying rust remover "draws out the stain” and the diatomaceous earth then absorbs it.

Remove the poultice with the spatula. Wet a sponge with distilled water and rinse off the marble.

Dry the marble using a clean cloth.

Repeat the entire process if rust remains on the marble.

Warning

Be cautious when using the rust remover. These products contain strong acids. If concerned, wear rubber gloves as a safety measure.
