Use a sponge and antibacterial soap to wipe down the outside of the luggage. For best results, use lukewarm water. Avoid using chemical-based cleaners, as this can damage the bag. Laundry detergent can be used to spot-clean any tough stains that remain after hand-washing. The inside of the bag can be sprayed with air freshener to remove odors and keep fresh. Again, avoid using harsh chemical fragrances as this can damage the bag.
