Serious question, is a rotary brush on clay tile ever the right call, or are we all just scared of the poly}
Had a 1920s bungalow over on Fremont last Tuesday, and the flue was caked with 3/4 inch of glazed creosote that the brush just polished instead of pulling. Half the old timers I know say chemicals and a poly whip every time, but the other half swear by the rotary for anything past a certain thickness, so where do you all land on it?
