“No, because abrasion affects the material (PU coating) and causes damages over time. Detergent residues often remain as well. For sensitive skin types, this can cause skin irritation, e.g. at the shoulder straps. A chemical reaction caused by sweat, detergent residues, and UV radiation promotes the faster decomposition of the materials.
The best way to clean the backpack is by laying it in a bowl or bathtub, depending on its size, and washing it with pH-neutral soap or shower gel. Any dirt on the backpack can be easily removed with a brush. Salt edges on the wearing system can be rinsed off by pressing the material together multiple times by hand using soap and plenty of water. Must be stored in a dry environment!”
Empty the backpack completely after each trip. Remove stains by hand with a simple soap solution and a brush.
Do not put the backpack in a washing machine or dryer as this will damage the PU coating.
Backpack material is not generally suitable for ironing.
Keep zips free of dirt.
Fasten the belts for storage purposes and keep in a dry, well-ventilated area.
