Detach a strip, fold it in the shape of an accordion, place it on its edge on a heat-resistant support, light it then blow out the flame to avoid igniting it because it must burn slowly. It is also used without being consumed. Detach whole sheets and place them in chests of drawers, dressing rooms, cupboards, books. Burn a strip 3 to 4 times a week. Ventilate the house regularly. Do not leave a slide burning unattended.
