Cleaning roaster ductwork

[dfluke]

I have a bmhg roaster set up at home with some four inch ductwork which is getting pretty caked with some chaff dust or whatever it is. I use a vacuum cleaner motor with a home made wood/dust collector type thing for chaff collection and smoke removal.

 I was just curious how others have handled cleaning their roaster ductwork. I was thinking one of those 4inch brushes for dryer vents would work quite nice but not having done this before was interested in what others think.  Thanks.

You need to scrub it so yes the 4" dryer brush works well.  I normally disassemble my duct and use a brush and a water hose.

If it looks sorta like this, it's creosote buildup, and it is very flammable.



If you can't brush it out, keep your local FD on speed dial.

It seems to wipe off with a rag pretty decent but I'm planning on getting real 4 inch ducting vs. the flexible I'm using on part of it right now so I was concerned long term how I would handle the cleaning. It wouldn't be difficult to mount in a fashion that is easily removable.
