Soot and carbon build up in your firebox as a result of using your fireplace. Soot and carbon build-up can eventually lead to smoking embers and smoke can back up inside the house. In bad cases fire damage can result from a backed up fireplace and chimney. Use a soot and carbon removing spray to help clean and prevent soot from accumulating.

  1. 1

    Purchase a gas log carbon and soot remover spray such as the spray available at the Fireplace and Chimney Supply website (see Resources).

  2. 2

    Confirm your gas fireplace is off before cleaning. Set the nozzle on the spray cleaner to "Spray."

  3. 3

    Spray the logs in your gas fireplace with an even layer of the soot remover. You may also spray a layer along the sides of the lower chimney wall.

  4. 4

    Allow the spray to dry completely before using your gas fireplace again. The spray will not only remove the soot but will also help to prevent soot build-up.
