Wash a hiking backpack by hand when its manufacturer's care instructions allow it; a dirty patch can often be cleaned with a damp cloth. Empty every pocket first and let the pack dry completely before storing it.
Empty the pocket at the bottom too
Sand from a weekend beside Lake Siljan in Sweden can travel home in side pockets and lower compartments. Remove the rain cover, sit mat, food and anything left behind an internal divider. Open the pockets. Shake out the crumbs. An empty pack is easier to clean without dragging grit across the fabric.
I would spread the contents on a table while the pack is out. That also reveals the empty sweet wrapper and wet sock that might otherwise end up in storage. For rearranging the contents afterwards, see the separate guide to packing a hiking backpack.
Match the cleaning to the dirt
A few muddy splashes need not mean soaking the entire harness. Deuter's care guide recommends a damp cloth for light dirt and advises against machine washing. Check your own model before choosing detergent or filling a bath.
Try a small area first. Work with a soft cloth or brush, especially around seams and coatings. If the inside is sticky or material is peeling, more scrubbing is not necessarily the answer; ask the manufacturer what can be repaired.
Follow the model's hand-washing instructions
Bergans' backpack-care advice specifies hand washing at no more than 30 °C, a mild cleaning product and gentle cleaning. Rinse the product out thoroughly. That temperature limit is manufacturer advice, not a statement about every backpack on sale.
Osprey's guide advises against a washing machine and describes cleaning with mild soapy water and a soft brush. Where the harness and hip belt are designed to detach, they can be cleaned separately. Do not pull out a frame or unscrew parts simply to fit the pack into a basin.
Imagine having 2 evenings at home before the next trip. Wash on the first evening, leaving time for the padding to dry and for reattaching parts that are intended to be removed. Do not plan around the outer fabric feeling dry after an hour.
Let air reach the padding
Open compartments and arrange straps so damp sections are not pressed together. Osprey recommends air drying in a ventilated place out of direct sunlight. Do not tumble dry. Check the back panel and hip belt before putting the pack away.
The rain cover may have separate care instructions. Do not return it wet to its small pocket. If your jacket needs cleaning too, follow its garment instructions: the method for washing a waterproof jacket does not automatically suit a backpack.
Store the equipment and keep the trip
Once dry, the pack can be prepared for another departure. Photographs from 3 different tent pitches are easier to find when they belong to the right place. In FARON, you can attach a photograph and note to the overnight place on your map. Log your first night while you still remember which bay appears in the picture.
Frequently asked questions
Can I machine wash my backpack?
Only do so if the specific model's care instructions expressly allow it. Osprey and Deuter advise against machine washing in their guides.
Must the whole backpack be soaked?
No: light dirt can often be spot-cleaned with a damp cloth. Follow the model instructions for more extensive cleaning.
Should I remove the frame before washing?
Remove only parts the manufacturer identifies as detachable for care. A frame may be designed to stay in place.
When can I put the backpack away?
Store it once the padding, pockets and straps are dry too. Dry outer fabric does not mean the entire harness has dried.
