Pulled 4 creosote logs out of a Cincinnati duplex last Tuesday and the flue went from black to clean in 3 weeks
I swept this place on Dennis Street back in early March and the flue was so caked I could barely get my 8 inch brush past the smoke shelf. The owner switched from burning green poplar to seasoned oak and ran it hot twice a day, and when I came back last Tuesday the glaze had flaked off on its own. Has anyone else seen creosote break down that fast from a fuel change alone, or am I missing something in how they were running the damper?

Three weeks? That's not creosote breaking down, that's a chimney doing some kind of magic trick. Sounds less like a fuel change and more like a case of the homeowner leaving out the part where he called in a buddy with a rotary whip while you weren't looking. Green poplar is basically wet cardboard in log form, so yeah, switching to dry oak and running it hot will cook that gunk down to a crisp. But glaze flaking off on its own in three weeks from a fuel swap alone? Sure, and my brush cleans itself too.
