Place the oil burner on a heat-resistant, stable surface and never leave lit candles unattended. Use standard tealight candles only, and add a few drops of fragrance oil or a wax melt in the bowl above. Extinguish the tealight and allow the burner to cool completely before touching or refilling. Clean cooled wax or oil residue with a soft cloth; avoid abrasive cleaners. Keep out of reach of children and pets and away from flammable materials.
