I bought a new wood stove this fall. Because I have such a small house I have to keep the damper and draft all the way down. As a result my chimney builds up pretty bad. I have the double wall pipe and have had one chimney fire so far, that was scary ! I cleaned the pipe today with the round wire brush and now burn Kwik-shot soot stopper once a wk. It still looks bad. What would be the best way to keep the pipe clean and safe ? Thanks for the help .
