Hi, HELP!! I have a wall to wall brick fireplace with step up hearth. Over the years I have had plants, etc. sitting on the hearth. Unfortunately it has now been stained by water overflows, etc. Most of the time I clean with a damp cloth, but it has gotten worse over the years. I have no idea what or how to use solutions or tools to try and bring it back to original look without using a blow torch or sand blaster. Do you have an answer? pattymou@zoominternet.net
