To keep your candles in optimal condition, avoid high temperatures to prevent drooping and maintain their straight shape. Burning in a draft accelerates burning and dripping. Store candles flat to prevent warping, and trim the wick to 1 cm before lighting to promote even burning. Extreme cold can cause wax to crack, so avoid prolonged exposure to freezing temperatures. Following these simple guidelines will ensure your candles burn beautifully, drip free, and last longer.
