We just let the dampers on full open for 5 min you can see the black cresasote on the walls and doors of combustion chamber, 5 min later a huge amount of heat and your pipes are clean. No scrubbing no chemicals. Can do this once a month on fireplace to maintain it. We have had flames. Like a after burner blue hot , shot 20 feet past the top of the chimney for 10 minute burn,.lots of heat inside the insulated part barely warm to touch and the pipe leaving the top of stove so hot you could not get hand within 2 feet of it without pain from heat. Zero damage zero warping no fire risk.
