Product Instructions: 1. Firstly, take a quick look at our warnings and instructions on the base of the candle and inside the box. 2. Always burn for a minimum of 1 hour to prevent ‘tunnelling’. 3. Do not burn for longer than 3 hours for our Standard & Deluxe Candle and 2 hours on our Mini Candle. 4. Before re-lighting always trim the wicks to 5mm and ensure they are upright. Trimming wicks reduces smoking and ‘mushrooming’. 5. 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.
