Trim wicks to 1/4” with each burn. Place candle on a heat resistant surface or candle tray. Allow wax to melt to the candle’s edge every burn to prevent tunneling. Keep candles away from drafts to ensure a smokeless, clean burn. Use a wick snuffer to extinguish a candle without soot or smoke. Discontinue burning a candle when less than 1/4 of wax remains.
