So my chimney guy showed up this morning to seal my crown. So I thought, he ended up not havin the stuff but my liner had extended a few inches so he whacked that off an while he had the cap off decided to clean it. I jus got off at 7 this morning and I'm like sure go ahead bub. Well brain fart, stoves still together now my insulation blanket is pretty covered. I want to clean it but it feels like it'll rip pretty easily so I'm wonderin the best way to do it?????
