drawstringbackpack

For dirtier backpacks, you can use a mild detergent or bleach-free fabric softener. Pour the detergent into a large mesh laundry bag and shake vigorously. Then, rinse the backpack in cool water. Follow the washing instructions on the detergent label and leave it to dry on a hanger or liner. It's best to hang the backpack to dry, as sunlight can damage some fabrics. Once it is dry, you can clean it using regular laundry detergent or a detergent made specifically for drawstring backpacks.
