To keep your backpack clean and in good condition, wipe it regularly with a damp cloth and mild soap to remove dust and stains. For deeper cleaning, hand wash or follow any specific care label instructions. Always air dry the bag in a shaded area—avoid dryers or direct sunlight for long periods to prevent fading or damage. After use, empty the bag to avoid odors and moisture buildup. Store your backpack in a cool, dry place, and avoid overloading it to protect the zippers, seams, and straps. With regular care, your backpack will stay durable and ready for daily use.

To keep your cabin bag in top shape, wipe the exterior regularly with a damp cloth to remove dust and dirt. For fabric bags, use mild soap and water for spot cleaning—avoid using bleach or strong detergents. If it's a hard-shell bag, clean with a soft cloth and mild cleaner, and avoid scratching it against rough surfaces. Always let the bag air dry completely before storing it. Keep zippers and wheels clean and free from debris to ensure smooth movement. When not in use, store the bag in a cool, dry place away from direct sunlight or heat, which can warp or fade the material. Don’t overstuff the bag, as this can damage the zipper or strain the structure. With regular care and gentle handling, your cabin bag will be ready for every trip, big or small.
