Cleaning up 60+ years of oil furnace chimney soot? Answered
The chimney is gone, leaving a large (about a bushel sized ) heap of oil soot on a concrete floor. Some has been shoveled up along with the mortar dust. There remains about a bucketful spread around a 1.5 meter square area... plus foot and paw prints over a larger area of new concrete. (I will be checking soon to make sure everyone and the dog are OK.) So what is the right way to contain this mess and get it safely out of the house?
