Our products have been made by double coated water-resistant polyester material. It makes it easier to clean whenever needed. In case your bag has gotten dusty after a trip or while in storage, just take a wet cloth / sponge & swipe it clean. In case of a heavy stain, just dip the wet cloth / sponge in soap-water before swiping it clean.
When the luggage is not in use, we would recommend storing it at home in the packaging (dust bag & hard box) in which it was shipped to you. This would avoid the bag getting dusty when kept in storage for long periods.
