I've got an odd-sized liner (approx. 6" x 10"). Unfortunately, the right-sized brush is
a bit of an oddity, costing anywhere from $70 - $85! The bummer is that you can get
a 7" x 11" nearly anywhere for approx. $20 at most hardware stores.

This makes me think about getting out the wire snips and trimming a bit off of the
larger 7" x 11" brush to get it down to size, and thus save a ton of money.

Any input ???
 
Metal or poly? When testing the brush, don't push it down too far before trying to reverse it.
 
For my money, I'd take the snippers to it. Not sure exactly how much bigger than inside flue measurements you want the brush to be, but I'm sure someone here has that info on hand.
 
Metal would be a little harder to cut with snips. You need to make sure that the brush is stainless steel if the liner is SS as you should not use dissimilar metals. Poly should be used for SS liners and metal for clay liners.

I have to trim my poly brush- it wont reverse in my liner. If you have a metal liner- get a poly brush and trim.

I've yet to find a rectangular brush that is poly, much less for odd sizes.

Quite a few sites I've searched, with no results.

Sounds like a clay liner and not a SS 6x10 liner - that would be odd no?

As for the brush, dissimilar metals?? Where does that come from. Regular metal brushed work just fine on SS liners. I am fine with folks liking poly but knocking the metal brush is BS. Those brushes do not harm the liner. I have looked at mine pretty closely up top as that is where my liner gets dirtiest and gets a few more passes with the brush and it is in perfect shape.

Great that yours hasn't caused any damage - but a metal brush can scratch up a stainless liner ...hence polly brushes
 
I've worked around stainless steel and welders in heavy construction enough to know not to use the wrong brush on SS. Google is your friend if you want an in depth explanation.

As for rectangular versus oval versus clay versus SS, the OP did not specify but more information is better than not enough.
