Candles are a great addition to any home, but there's no denying that the smoke they can sometimes produce is irritating. They can set off smoke alarms and they can irritate those with breathing difficulties. To prevent this smoke, you might want to try out this old-school hack, which involves trimming the candle wicks before you light them. Ideally, you should cut the wick so it's 1/4 inch in size.
By doing this, the flame will be better contained and will reduce the amount of soot that builds up while it's burning. As if that wasn't enough, it should also make your candles last longer.
