Since all waxes create soot, it's wise to ensure that the space where you light your candle is well-ventilated. Breathing in any type of smoke can be hazardous — and candle smoke is no exception, especially when contained. Lots of ventilation and steering clear of burning your candles in drafty areas can help to reduce the amount of smoke they release.
If you're a candle lover, you'll know the pain of burning through your favorite scents in what seems like no time at all. And no matter the size or price point, the less you burn your candles, the quicker they seem to disappear.
Firstly, when you first buy or receive a new candle, you need to set it up for success. You should always burn your candle for a couple of hours when first lighting it, to allow the top layer of wax to fully melt, ensuring even burning when next lighting it.
Secondly, you need to be strategic about where you place it, as heat will make candles sweat, and placing your candle in a draughty area will consume the candle more rapidly.
Lastly, if you want your candles to last longer, you should trim your candle wicks after every use.
