My old boss swore by a stiff wire brush for every flue, but I switched to a poly brush for most jobs
He'd say you needed the steel to really scrape the creosote, but after a job in Boulder where I scratched the heck out of a delicate clay liner, I changed my mind. The poly gets it just as clean on standard tile without the risk. Anyone else make the switch and find it works better for certain liners?

My old man ran a crew in Denver for 30 years and had the same rule. I keep a steel brush for the really bad, glazed creosote jobs in heavy masonry flues, but for probably 80% of the tile liners I see now, the poly is the right tool. It's just less likely to cause damage you won't even see until later.

That's fair. I just see too many guys in the field leaning on poly brushes for stuff they shouldn't. A dry poly on packed-in glaze won't do anything but polish the stuff, and then you get a call back six months later.
