Would appreciate feedback on my sweep job

[PDutro]

This is year 4 using of our RSF Focus 3600. We love it, and burn dry wood exclusively (<20% MC). I have been sweeping it myself and other than some light soot I never have any buildup that I can see, but I appreciate feedback from the experts here.

Our chimney is 8” (6” inside diameter) double walled stainless steel class A, 13 feet straight vertical run.

I use a Heartland 6” poly brush, and sweep once per year before we start using the fireplace. It’s looked the same before and after sweeping each year. I am wondering whether I should invest in a second brush, maybe a soot eater, to get a more thorough clean but then again, with the set up I am using I am not seeing any increase in soot nor any creosote (as far as I can tell).

First three pics are prior to sweeping. The next two are after sweeping. Then a pic of my brush, followed by the cap before and after wiping it off with a paper towel, then a pic of inside looking up into the flue opening, and finally the pile of soot resulting from the sweep.

Feedback super appreciated, thanks.

Follow up, a quick wipe with paper towel exposes bare metal again.

That's what's known as a clean sweep and a testimony to burning dry wood properly. Well done.

Looks like the chimney gets pretty clean to me. No gooey or crispy buildup which is good.
