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”.
