“Before lighting your candle, be sure to trim the wick to about five millimeters to avoid any unnecessary smoke, which causes soot to form in the candle," said Eduardo Valadez of Diptyque Paris.
The bigger the wick, the bigger the flame and the faster your candle will burn. A short, trimmed wick will help your candle last longer, emit a stronger fragrance, and help prevent carbon buildup on the wick, which leads to black soot deposits around the candle jar.
“Wait to trim the wick until the wax hardens again," said Rossi. "This way it doesn’t fall back into the melted wax. If the wick clippings remain in the candle, it will eventually travel to the wick and this debris will clog the wicks, blocking the scent from diffusing. You can’t smell the scent.”
