With unseasonably warm temps I think I'll clean my chimney.I'm not going on the roof,too much snow!! but It's easy to clean chimney pipe from from inside. With a heavy duty garbage bag chimney brush with long rod and some duct tape...I just take apart everything from the ceiling down and clean that outside.Than I duct tape the bag around the flange at the ceiling, with the brush inside,make a small hole in bottom of bag just for the rod to poke out ..than brush away everything falls into the bag!! Works pretty good without much mess..
