Cleaned my chimney liner - pics and question

[wahoowad]

I've had my 6" flexible chimney liner in for a few seasons now. When I clean it I'm just knocking loose soot off with the 6" plastic brush but it seems like lots of soot stays in the crevices. I bet just as much stays in the cracks as gets knocked loose from the very inner surface. Is there a better approach for a DIY homeowner to clean the flex liners?

Try the sooteater rotary tool. It’s a whip that spins. May hit those crevices with more detail

That is a good suggestion. But the top of your liner does not seem to be terminated properly at all.

How so?

How so?

The insulation is exposed on the top edge. That allows moisture and creosote to sleep in. The outer liner should be cut below the top plate any the top plate should be smaller so it clamps to the inner liner.

You got a pic that shows it like that?

I do not. But if that insulation gets wet and saturated with creosote it can't possibly do it's job
