I have a question about those chimney sweeping logs. Are they affective in any way? I use my main fireplace in the living room some nights when it's near freezing here, so as many as ten or twelve times a season. It's an insert that draws air from the outside and blows warm air into the room. I tried cleaning the pipe out a few years ago and it had a barely discernible scale of what I took to maybe be creosote. I've looked at it a few times and any coating I see seems to be negligible. Each winter I burn maybe a couple of those chimney sweeping logs and just bought one not too long ago to use.
