Hotspot Fireplace Cleaner removes smoke, soot and tar stains caused by wood, coal and gas fires. It is suitable for use on brick, stone, concrete, marble and other hard surfaces. Brisk brushing creates a foam that cleans right down to the pores without damage. Eliminates the need for harsh, damaging acids. Ensure the surface to be cleaned is cool, remove screens, fixtures etc. and protect floors and carpets.
