I made a trip to Menards to find something to clean out the inside of my frame. Found this rotary chimney cleaning system with quick-connect whip lines and a drill adapter. If someone has used this before and had a post about it, I didn’t see it. I had a 6” steel flue ball that I was going to try a pull thru the frame, but couldn’t get it to go into the frame, even after I trimmed down some of the metal wire. After a few passes down each frame channel with this rotary cleaner, I couldn’t believe the mess on the floor. I will replace the strings and grab a new battery for the drill and hit both channels again. This is making quick work out of this job.
