To lubricate shipping container door hinges, first unload pressure from the door, clean dirt and corrosion from accessible pivot areas, confirm the frame is not twisted, and apply a small amount of the lubricant recommended by the container supplier or hardware manufacturer. Cycle the door carefully and wipe away excess. If the leaf sags, scrapes or remains stiff, lubrication is not the repair.
