Do gas logs require any special maintenance?
Outside of periodic professional inspection of its gas lines, valves, connections, and pilot, gas logs require no particular maintenance to remain in proper working order. If you wish to clean your gas logs, first make sure they are off and have cooled to room temperature. Brush gas logs with a soft bristled brush or duster to remove any dirt or dust. Do not remove gas logs from the burner or the fireplace and never use water or other solvents to clean gas logs.
