Hello, I attached a photo of my chimney that I cleaned/brushed from the roof today. It seems very clean to me, but I question whether the small amounts of glaze are actually dangerous or normal to have trace amounts. My plan is to install a new stainless rigid liner inside my current clay liner which is in the photo.
