How do you clean a watershed duffel bag?

To clean a watershed duffel bag, first empty all pockets and remove any loose dirt or debris. Use a damp cloth or sponge with mild soap to wipe down the exterior and interior surfaces. Rinse with clean water and allow the bag to air dry completely, avoiding direct sunlight. For stubborn stains, you can spot-clean with a gentle fabric cleaner, but always check the manufacturer's care instructions for specific recommendations.
