Specific instructions on how to wash an L.L. Bean backpack are not provided on the L.L. Bean website, but these backpacks can be washed using general backpack washing instructions. Most instructions recommend using a mild detergent and cool water to safely and effectively wash a backpack.
In general, the following steps can be followed to wash any type of backpack, provided it is not leather.
Step 1: Empty the backpack
Make sure every pocket and section of the backpack is empty. Leave all pockets and sections unzipped, and, if there are any wash instruction tags, read those before washing to make sure it is safe to wash the backpack in water.
Step 2: Remove straps and metal parts
If the straps are removable, take them off and wash them by hand so they maintain their rigidity. Soak for 30 minutes in warm water and a mild detergent if they are stained, and then scrub with a brush. Rinse them in cool water and then hang to dry.
Step 3: Pretreat and wash the backpack
If the backpack has stains, scrub them gently with a mild detergent and cool water. Place the backpack in an old, large pillowcase, and wash it using the gentlest cycle available on the washing machine with cool water and a mild detergent. Once it is washed and ready to dry, wipe down all pockets and compartments with a towel and then air dry. Drying the backpack in the dryer or in the sun may cause it to lose its shape.
