To bring a tunneled candle back to life, pop the candle in a 175-degree oven for about five minutes. The distributed low heat helps melt the wax, making it smooth and level across the top again. Pro tip: Keep candles away from walls, because heat or soot can leave an unsightly black mark. Instead, use a candle snuffer—like Madala Candle Snuffer ($7; amazon.com)—to extinguish the flame. Snuffing keeps the wick in place, prevents that post-burning smell, and eliminates dangers associated with blowing on hot wax. Plus, it’s fun to use! P.S. Save a few lids from spent candles, in case a future candle doesn’t come with one.
