How do you get gunk out of a Swiss army knife?

To clean gunk out of a Swiss Army knife, first, ensure the knife is fully closed and disassembled if possible. Use a soft brush or toothbrush to gently scrub the crevices and tools, applying a small amount of mild soap or isopropyl alcohol if needed. Rinse with water (if safe) and dry thoroughly to prevent rust. Finally, apply a drop of lubricant to the moving parts for smooth operation.
