Looking after the wick of your candle is extremely important! Before lighting, always ensure your candle wick is trimmed to approximately 5mm. By trimming the wick it will remove any 'clubbing' - the build-up of carbon that can be visible at the end of a wick, prevent the candle from sooting - black marks that will form around the edge of the candle glass, ensure better scent diffusion and prevent high flames which are unsafe
