Can I use an art gum eraser to clean fireplace brick?

If your fireplace has soot and smoke debris, you can use an art gum eraser to remove it. All you need to do is rub the eraser on the brick and it will erase the dirt, just as it erases pencil on paper. It does take time, and it is best if you work in one small area at a time. There will be a lot of debris on the floor from the eraser, so you may want to lay paper down to catch it to make cleanup easier. Also, when you are finished you will need to brush the brick to remove excess eraser from the brick, or you may vacuum it.
