We used to have a large ficus tree on our marble floor. When it died, we removed it and found a brown stain where the plant had sat. What should we use to remove this stain?

The brown stain is the result of minerals from the soil of the fichus tree. This type of stain is difficult to remove and will require a poultice. Refer to the book “Stain Removal Guide for Stone” and apply the poultice as instructed.

TIP To remove the stain try a poultice with 50% hydrogen peroxide. Let the poultice stay on the spot for at least 24 hours. If the peroxide doesn’t do the trick you may want to try a product called “Iron-Out”.
