Burned all last year, Got a coffee can full of brown fluffy stuff out of the pipe. Had some glazed chunky stuff on the cap. Seems pretty good to me
I got about the same out of last years cleaning. My sweep come the last week of Sept. Fingers crossed for the same results or better.
I just swept my chimney last Sunday (first year burning with not great wood) and got about a big can and a half on top of the crud that was left in the trap from previous owners. All things considered, I was happy with it. I cannot imagine how people let their chimneys go so long to the point that they are like clogged arteries. It boggles the mind!
I did take a couple of pics up on the roof before I cleaned ,the cap looks worse in the pic than it is though
I gotta believe that those cases are where 90 percent of chimney fires come from. I cant believe that if I clean mine regularly that it will ignite causing the house to burn down.
