sootiest
Darkest with residue
Sootiest is the superlative of sooty—most covered with or resembling soot.
Soot is the black powdery residue from incomplete combustion, so sootiest describes whatever has the most of it: the sootiest chimney in the neighborhood, the sootiest corners of the old factory.
