To have your bag shiny and polished without any fingerprints, you can wipe it time to time with any polishing cloth. I personally use chamois leather cloth. The outer surface of the bag is non-absorbent, so if you spill something over it, just wipe it with a damp cloth. Please do not try to wash it in a washing machine, as this would most likely break your applience. Well, I’m sure you will treat it as you treat yourself, let’s see how does that go. 😉
And one little Attention note! Do not keep it for a long time on direct sunlight in heat above 30°C. The heat can cause the form to change it shape.
