Try in the same day. Kind of comical when there is a sticky up top on this forum about lazy fires, dirty glass etc .. , hell it even shows pictures of acorns in the works. Then we get videos and stories about bees, bats, birds and squirrels all expiring in the exhaust system. We even had a recent case of where mice had added caramels to the works. Well we had company here yesterday so the stove didn't get cleaned, the boss is heading to the next state over shortly so I just turned the stove off for its weekly cleaning. I gave it its first deep cleaning last week so this will be to sweep the ash into the pan and other light work cleaning..
