if the backpack is too large to fit in the washing machine, you can wash it by hand in the bathtub. Small backpacks can be put in the sink or washbasin. Be sure to check the label to make sure the backpack is completely submerged.
1. Empty the backpack and check all pockets and corners for small items or dust. If your backpack has a metal frame, please remove it before washing.
2.Pour plenty of warm water into the bathtub or washbasin. If the water is too hot, it may cause the color of the backpack to fade.
3. Add a small amount of soap without detergent to the water. Do not use ordinary detergents or fabric softeners, as this will damage the backpack, especially the waterproof backpack.
4. Wipe the backpack with a soft brush or cloth, focusing on the particularly dirty place. Toothbrushes are useful for any stubborn stains or for entering areas that are difficult to reach.
5.Let the backpack dry naturally. Hang the backpack upside down as much as possible, and make sure the backpack is 100% dry before storage.
