| One of the buildings that we clean has marble walls. These walls have a yellow stain on them. I cannot positively identify the stain. It resembles smoke stains from tobacco smoke or residue from sulfur water, but I cannot be sure. What do you recommend for removing these stains? |

Go to www.marble-institute.com/consumerresources/care.cfm and look down the list of possible staining sources. You may need to try several poultices to see if any are effective. Choose a small spot and do an experiment. If that is successful, you can proceed to larger sections.
You will need time and patience. Marble will absorb substances and it takes time to draw them out. Sometimes you will not succeed, depending on the substance and the length of time it has been there.
