How can we really make our candles last as long as possible? Well, it all comes down to the very first burn.
There are some simple care and maintenance steps to follow. 'The first burn is the most important,' say the experts at Yankee Candle. 'Always trim the wick to 3mm (1/8 inches) before lighting and keep it trimmed while burning, this will help to prevent smoking.'
To do this, simply trim the wick every few hours of burn time. When wick trimming, always extinguish the flame, let the candle come to room temperature, and then trim the wick to 1/8 inches before relighting.> Related Article6 ways to make your home smell amazing
