Yes it is now summer, but never too late for pellet talk. I just did my stove tear down and super clean. I had really bad experience with Turman pellets, returned one ton that had 3 inch long pellets, my other ton did not burn "Turman" hot and caused black sticky build up in stove. After hours of scrubing w/ wire brush I did get inside clean. I then decided to clean pipe. The black sticky stuff was in pipe and ruined my brush. Any idea how I can get my stove pipe clean again? How clean should it be? Am I worrying too much? I am just afraid of a fire in the pipe next season when I burn. Any info would be appreciated.
