I used to think those flexible chimney liner brushes were just a gimmick.
Had a tough job in an old farmhouse near Salem with a really narrow, winding flue that my regular gear couldn't handle. I borrowed a friend's poly brush and it got the job done in under an hour, which changed my mind. Has anyone else had a good result with them on a specific type of flue?
Funny you should mention that. My old boss swore they were junk for years. We had a job on a historic property with a flue that had two nasty offsets. The rigid rods just would not make the turn. A flexible brush snaked right through and cleaned it perfectly. They are not the right tool for every job, but for those tricky old flues, they are a lifesaver. I keep one on the truck now for just that reason.
