We always recommend avoiding the temptation to use a leather care cream on your M&B. bag.  As faux leather is not an animal product, the leather care creams don't work the same way. This is, however, a great benefit of faux leather because 99% of stains or marks can be cleaned away with a light damp cloth and mild soap. (non-scented antibacterial kitchen wipes work great too!)Please please please, do not put your nappy bag in the washing machine or submerse in water.
