Wick Trimmer for candle maintenance. Candle Care Tip: Before re-lighting your candle, you should always trim your wick to 1/4 inches. This wick trimmer allows for a clean and easy disposal of your old, burned wick. This wick trimmer collects your old wick debris in a small saucer so you can dispose of the burned wick without getting your fingers dirty. The long handle of the wick trimmer allows you trim any wick, even if the wax level is at the bottom of your candle.
