HELP: Does this liner look safe to burn?

[dreezon]

I've got a WS Fireview, but this being my first season, I've been forced to burn some marginal wood. I just pulled the cap off the Tee to check my liner, and this is what it looks like.

I would just go up and do a sweep to err on the side of caution, but weather, etc. is making it unsafe for the foreseeable future. I was pleasantly surprised how clean the liner looks. Seems like just a light, brownish-gray dusting, but what do you think, those of you who have more experience? Does this look safe? Do I need to sweep ASAP? Can I burn until the weather improves. Can I wait till spring? I did manage to hit the lower end (below the ovalizing) and the horizontal pipe going to the tee. Those parts seemed worse than the actual liner.

Also, any tips for how to sweep the ovalized part? That poly brush is pretty stiff.

Get to about an evenly distributed 1/4" of sooty black deposits around the inside of that liner, and it's time for a sweep. Until then, it's looking just fine. Rick

(Yes, Hanko, I finished your editing for you...strictly G-rated around here, remember...I did get a chuckle out of it, though)

Dreezon, doesn't look bad to me. The oval part will have to have an oval brush.

There is no way to tell from there what the top end looks like. But chimney fires start at the bottom and there isn't anything there that is going to start a chimney fire.
