sooting
Coating with residue
Sooting is the process of becoming coated with soot—the black carbon residue from incomplete combustion.
Chimneys and exhaust pipes soot up over time.
In technical contexts, sooting describes carbon buildup in engines or furnaces that reduces efficiency: The injectors were sooting badly.
