The time has come....
I have a fireplace insert, SS chimney liner.
The interior dimensions of the liner are about 7" x 4", oval.
I looked around and could not find a poly brush that even came close to these dimensions, so I bought an 8" round brush figuring that I could cut it down to the right size.
So my question - Do I cut the bristles to be an exact fit, or do I cut the bristles slightly larger than the chimney dimensions?
Of note, the liner does transition to a 6" round for about 12"-18" of chimney at the top of the insert, so brushing will need to easily change directions.
As for that first 12 or so inches that is the 6" round, should I get a 6" brush, or should that part be clean enough for how close to the fire it is?

- +1/8" ( +1/16" on each side)
- +1/4" ( +1/8" on each side)
- +1/2" ( +1/4" on each side)
