Looked for chimney brushes locally. Everywhere is out. I have a class A chimney, 6 inch. So, I would assume I need to order a 6 inch poly brush and rods. My question is about cleaning the stove pipe. Do we use the brush to also clean the stovepipe? Or do we remove stovepipe to clean it? First season with woodstove. Stove also has a baffle. Someone on this site gave us a good way to clean stove with baffle. Remove 1st section of stove pipe, secure a trash bag around stove pipe to catch any debris. Any brands of brushes better than others?
