A few tips to ensure you get the most out of your candle. Firstly, take a quick look at our warnings and instructions on the base of the candle and inside the box. Always burn for a minimum of 1 hour to prevent tunnelling . Do not burn for longer than 3 hours for the Standard & Deluxe Candle and 2 hours on our Mini Candle. Before re-lighting always trim the wicks to 5mm and ensure they are upright. Trimming wicks reduces smoking and mushrooming . Lastly, never use the lid or water to extinguish your candle and always extinguish your candle when there is 10mm left at the bottom of the jar. That s when you know it s time to buy a new candle.
