You can wash your bag by hand (please do not use a washing machine).
In our printed fabrics, we use processes that minimize chemicals. Do not twist or scrub fabric, as this could stretch, deform, or damage the print. In the case of stains, rubbing can even ensure that the stain penetrates deeper into the fabric. It is best to soak the bag for a few minutes until it is clean. 30 minutes should be enough for this.
