Top down with a brush, no cleaning agents, I tape a trash bag on the bottom to catch all the creosote. I have to take off the top 3' section to be able to reach. It is tripple wall metalbestos
Doing mine now as I write. Do most from bottom up as my chimney is 32' and not reachable from the roof. Once a year I get a lift or 40' latter to inspect and clean from top down. Have always used wire on my SS though and brush says OK for SS on the box. After you burn awhile on SS there is a slight coating that never comes loose and the bristles don't seem to get to metal anyhow. Got 2 45's in the run so fiberglass rods are essential.
I wonder if the reason that a poly brush is recommended is that they are more pliable and able to get into the individual ribs better than a steel brush.I have always used steel brushes on mine.
tesen - i dont think any flexible rod that is able to make a 90 deg. bend would have enough rigidity to go up another 36'. i can be wrong though. its happened in the past.
How hard is it to take off the top section? It sure would make it a lot easier.The metal one I take the top 4 foot section off,makes it easier,you got to take the rain cap off anyway.
You don't say what you're cleaning.Any tricks or tips that people who want to start should know?
Around my area and in over 30 years of burning stoves at one time or another I have never seen or heard of a nylon brush for SS stove pipe.. even at the stove shops around here I have never seen one.
IMO, what is so fragile in a SS chimney to warrant one? SS is tougher than a wire brush.
just my 2 cents.
For the same reason that a welder needs a dedicated SS wire brush to use when he is welding stainless. Steel bristles not only scratch the SS but they actually leave traces of steel embedded in the SS that can and will start to rust and once it starts it spreads to the rest of the SS.
