Have you ever noticed tiny oily droplets forming on the surface of a candle? This is commonly called candle sweating. It may look unusual, but it does not necessarily mean that the candle is damaged or unsafe to use.
What Causes Candle Sweating?
Candle sweating often happens when fragrance oil begins to separate slightly from the wax. Temperature changes are one of the most common causes. A candle may become warm during shipping, storage, or hot weather and then cool again, allowing small droplets to appear on its surface.
Are Soy Candles More Likely to Sweat?
Soy wax is sensitive to changes in temperature, so soy candles may be more likely to develop surface moisture or oily droplets. Candles containing a generous amount of fragrance oil can also be more sensitive to heat.
Can You Still Burn a Sweating Candle?
In most cases, yes. Gently blot the surface with a clean paper towel before lighting the candle. Do not rub aggressively, because this may damage the finish or decorative details.
Before burning, always check that the wick is properly trimmed and that no foreign material is present near the flame.
How to Prevent Candle Sweating
Store candles in a cool, dry place away from direct sunlight, heaters, windows, and other sources of heat. A stable indoor temperature is better than an area that repeatedly becomes hot and cold.
Avoid leaving candles inside a parked car, near a sunny window, or in a hot garage. When possible, keep unused candles covered or inside their original packaging.
Does Candle Sweating Affect the Fragrance?
A small amount of sweating usually does not significantly affect the candle. However, repeated exposure to high temperatures may gradually change its appearance and reduce fragrance quality.
Candle sweating is usually a response to heat rather than a sign of poor craftsmanship. Proper storage helps handmade candles retain their color, fragrance, and beautiful finish for longer.
