I was cleaning a flue in a 1920s house and realized my brush angle was wrong for a decade
The owner pointed out a weird soot pattern on the living room wall after every sweep, and it clicked that my 15-degree downward push was just smearing creosote instead of scraping it. I switched to a straight vertical scrub with my SootMaster brush and the next inspection camera feed looked totally clean. Has anyone else had a specific tool technique they had to unlearn?

Yeah, that vertical scrub is key for old flues. Good catch by the owner, and @the_charles is right about the lightbulb moment. Sometimes you just gotta relearn the basics.

Wow, that's a huge detail to catch after so long! I always figured a firm downward push was the right move for getting that gunk loose. Seeing the actual soot pattern proof must have been a real lightbulb moment. It makes total sense that a straight vertical scrub would get a better clean scrape.

Man, that hits home. I spent years using a flat bar for trim work before a carpenter saw me and asked why I was fighting it. He showed me how to tilt it just a bit to get under the molding without chewing up the wall. My hands hurt less the next day. You don't know what you're doing wrong until someone points out the proof.
