Q.I have outdoor white marble steps. The tree in front of my home leaks some type of moisture during the fall and mostly during early summer. It has stain my stairs. What can I use to clean the white marble steps?

A.Without much info I can only guess it is tannins and you could try our heavy duty mb-2  to clean it.Most likely you will have to poultice the stain out with 40 volume hydrogen peroxide/baby powder paste. Making a poultice is easy go to our site at www.stoneshine.com and look it up in the stonecare guide.Use our mb-4 to seal the stone after you have removed the stains.You can always find a pro to do this at www.stoneandtilepros.com

Good luck
