A janitor was a type of custodian that businesses such as restaurants, hospitals, schools and other business types hired for cleaning and maintenance.
Typically a janitor's job in-doors required sweeping and mopping while outdoors required mowing grass or washing windows and the paved areas, such as where automobiles were often parked.
Rudy Jones was a janitor at S.T.A.R. Labs.
Joseph Meach was a custodian of this type as well.
