Warning: I chose a poly brush over steel for a tough creosote job and it worked better.
Everyone at the supply house said to always use a steel brush on a heavy buildup, but I grabbed a poly one for a nasty chimney in an old farmhouse. It flexed around the clay liner edges and didn't scratch anything, plus it cleaned just as well. Has anyone else tried this on a bad creosote job?

My uncle's chimney business in Toledo always used steel brushes on stage three creosote. He said poly could leave behind a glaze that causes problems later. I saw @sagemurphy switched, but I worry about that hidden risk on a really bad job. Doesn't the softer brush just push the problem down the road?
