Advice needed on proper cleaning equipment

[egclassic]

I have been burning my new insert for about 3 weeks now and I was planning on checking/cleaning the "chimney" next warm spell.
My question is, what type of brush do I need for a corrugated SS liner? I thought I read somewhere that one should use poly brushes vs. steel on these flues or does it even matter?

Thanks

That is one of the great debates here . . . I personally believe the poly brushes work well and are especially good for the liners. Finding a poly brush at a local hardware store may be a challenge though . . . generally I have only seen them in woodstove shops and at on-line dealers.
