If you have an easy-care running backpack, it doesn’t take much effort to clean it. For this reason, it is worth paying attention to the specific properties of the material. In the case of a waterproof backpack, a waterproofing spray helps to maintain this repellent layer. The backpacks with hydration bladders must be cleaned regularly. To do this, the tube and bladder are cleaned and dried thoroughly. You shouldn’t forget the mouthpiece either, so that no bacteria form here. Special materials and brushes are available for some backpacks. The manufacturers recommend this accessory for reliable cleaning outside and inside. Normally, the drinking systems, including the bladder and hose, can also be cleaned in a water bath. If necessary, add a little mild detergent to the lukewarm water.
