The best way to wash a messenger bag will depend on the material it's made from. If the bag is made from a durable, waterproof material like nylon or canvas, you can typically clean it with a damp cloth or sponge and mild detergent. If the bag is made from leather or another delicate material, you may need our leather cleaning accessories or take it to a professional cleaner. Always check the care instructions for your specific bag before attempting to clean it.
