Several Fed Ex Freight shipping facilities had internal striping (used to help organize truckload shipments prior to loading) that was so dirty that it was hard to recognize and to use. Because the terminals are used 24 hours a day, there was no good opportunity to close areas for repainting. Gorilla Kleen utilized our hot water pressure washer and vacuum recovery unit to surface clean off the dirt and grime and make the striping almost like new again, all while the terminal was in use. No water could be left on the floors because it was too great of a slip and fall risk. Our system cleaned and literally never showed any water in the terminal, leaving the striping completely dry.
