Can we talk about the switch from steel brushes to poly bristles for flue liners?
I swore by steel for years, but after cracking a 20-year-old clay liner in Boise last fall, I switched to poly for anything pre-1980. Anyone else made the jump and had better results?

Honestly, what's the oldest flue you've cleaned with poly and felt totally safe about it? I'm still nervous on the really old, soft clay ones. I had a steel brush catch and pull out a chunk in a 1920s farmhouse flue last year, scared me straight. But I worry the poly just isn't rough enough on some of that built-up creosote.
