A roofer in Knoxville showed me his brush trick and it cut my creosote scraping in half
Was up in Knoxville on a job two months ago, old brick house with a wood stove the guy ran every day, and the flue was caked with that hard shiny creosote that laughs at a normal brush. The roofer working the same house came down and watched me fight it for about 20 minutes, then went to his truck and came back with a poly brush and told me to run it dry first before I ever touch it with the metal one. Said the poly gets under the glaze and flakes it loose, then the metal brush just sweeps the crumbs out. I was doubtful but I did it on his place and the stuff came off in sheets instead of me leaning on the rods like an idiot. Did the same thing on three jobs since then and every one took me about half the time it used to. He also told me never to mix the two brushes in the same bag because the poly picks up grit and chews up the flue. Any of you run a poly first on the nasty ones or am I the last guy to hear about this?
