No,,, really didn't get all of the carbon off. Left a slight black tinge of carbon. Now I had made a power scrubber by tying,,,, sewing,,, green Scotch Brite pads to a limber piece of wood,,, about like a yard stick and and almost as long and then taped to a saw-all blade and used saw-all. Have to have a limber stick so not to get too rough on thin metal Works good in between flues. I have drop flues so probably not going to work very well on raised flues back in ends of flues
