Poly brush over wire brush for tight flues? I made the switch and wish I did it years ago
I was doing a clean out in a old house in Philly last week and kept having trouble with a tight 6x6 flue. My wire brush kept binding up and it was taking forever. A older sweep I know told me to try a poly brush instead. I was skeptical because I thought wire was the only way to really scrape. Picked one up from the supply house and honestly it went way smoother. Got through the whole job in about 20 minutes less than usual. Has anyone else switched and noticed a big difference on those narrow clay liners?

My first poly brush was on a 8x8 flue last fall. Night and day difference. Never going back to wire for tight runs again.

Dude my buddy tried poly on a 9x9 last winter and said it was like switching from a shovel to a snowblower.

Wire brushes still do a better job on real buildup. Poly brushes just push the loose stuff around. That old masonry has decades of hard creosote. Wire actually digs in and scrapes it off. Poly brushes slide over it and leave a film. You might finish faster but you are not cleaning as deep. That leftover layer is what starts chimney fires.
