The hull of the Millennium Falcon displayed a significant amount of carbon scoring as a result of sustaining considerable damage over the course of many years.
Carbon scoring referred to the lingering residue from combustion and gaseous exposure, frequently observed on metallic surfaces of objects like starfighters or droids. C-3PO and R2-D2 both accumulated substantial carbon scoring following their departure from the Tantive IV and subsequent journey through the Jundland Wastes; Luke Skywalker took note of this during his examination of them. A tool known as a carbon chisel could be used for its removal.
