Three months of using a rotary brush finally paid off
I had a regular customer in a 1920s house in Cleveland whose chimney was caked with about a quarter inch of creosote. I kept hitting it with just standard rods and brushes, but it wasn't budging. Finally broke down and bought a rotary cleaning kit with a poly whip, and after three passes over two visits, the difference was night and day. Got the full sweep done in under an hour with barely any mess left behind. Has anyone else found a specific brush that works better for heavy glaze buildup?
