Hi all:<br><br>Limestone shower floor, had very poor caulk lines which led to moisture stain on wall. Drying it out but the floor has staining also, see pic. Went down to 50 grit metal which convinced me there is nothing on surface. Water damage or should I continue trying a poultice. Thanks in advance.<br clear="all">
