Yeah I don't understand chimney sweeping very much. The build up looked allot worse than it actually was. When I sent the brush up the chimney I hardly got and debris. Just some real real fine black powder, same with the
Thimble and DWSP.
I can re-describe the build up as 'Fluffy' if that helps.
EDIT: Poindexter: I have no idea what the rest of your post means ?
I had brown to gray looking dust with the tube stove and it is my understanding that this was fine and wouldn't burn. Black and crumbly is supposed to be bad and I wouldn't let it build up but I have known plenty who will let it build to the point they loose draft before cleaning. Black and shiny tar or liquid looking stuff is very bad. I learned my lesson with this stuff during a power outage in Dec. 09 and changed my burning habits drastically after that.
