To refresh the fragrance, flip upside down for approximately 5 seconds, then return upright. Refill as needed.

Important

Keep diffuser upright after saturating. Fragrance oil may damage surfaces. Immediately clean spills and avoid contact with dashboards, plastic, vinyl, leather, painted, stained, or finished surfaces.
