TIL a rotary brush is way better than a whip head for heavy creosote

I used a whip head on this old chimney in Philly last Tuesday and barely made a dent in the hard glaze. Swapped to my rotary brush mid-job and it shredded through that buildup in under 20 minutes. Anyone else seen a big difference between these two brush types on tough jobs?

barely made a dent in the hard glaze" - yeah that sounds about right with whips on old buildup. One thing nobody talks about: the brush material matters just as much as the type. I had a rotary with really stiff poly bristles and it still struggled on a 1920s coal chimney in NJ, but when I switched to a steel wire rotary it cut through like butter. Also check your motor speed, running it too slow with a rotary can actually heat up the glaze and make it harder to knock off.

Swapped to steel wire myself last month and it totally changed how fast I can clean old coal chimneys.
