Before painting the vintage items, they are thoughtfully cleaned and washed. So when purchased, they are as fresh as possible. If it were for the items to get dirty somehow or the smell is getting too bad: put the garment inside out and wash it mildly in a cold handwash. A little bit of laundry detergent can be added to the water. IMPORTANT: Don’t wash denim too often, even without the paint it’s bad for denim garments to wash them a lot. Leather items can NOT be washed, but that is formerly known.
