Tried a rotary brush on a liner job in Dayton, went back to my old poly rods after one sweep
Had a call about a glazed creosote problem and the rotary brush chewed through it in 20 minutes but left gouges I had to explain to the homeowner. Went back to my poly rods and hand scraping on the next one, slower but no damage. Anyone found a rotary setup that does not scar up the flue?
