Wick Trimmer vs Scissors: How to Trim Candle Wicks Properly

A wick trimmer cuts cleaner and keeps the wick centered better than household scissors. Learn how to trim candle wicks properly and stop tunneling with a simple diagnosis.
Quick answer
Use a wick trimmer rather than household scissors for a cleaner, centered cut at the right height. Trim to roughly 1/8 inch before every burn, and if you already see tunneling, start with a full reset burn rather than just snipping the tip.
Why a wick trimmer beats scissors for most candle care
Scissors can work in a pinch, but they cut at an angle, crush the wick, and often leave a frayed tip that mushrooms faster. A wick trimmer is designed to reach into the jar, hold the wick steady, and cut it flat at a consistent height. That flat cut keeps the flame even and reduces soot on the glass.
The trade-off is cost and storage: a trimmer is a single-purpose tool. If you only burn one candle a year, scissors are fine. If you burn regularly, the cleaner cut pays off in fewer trimmed-too-short wicks and less wax discoloration.
When scissors are the better choice
Use small, sharp scissors when the wick sits deep in a narrow jar and your trimmer cannot reach it without tilting the candle. Also choose scissors for very soft wax or a wick that is already loose and leaning, because a trimmer can pull it further off-center. In those cases, cut slowly and avoid crushing the wick.
Diagnose your wick problem before you cut
- Symptom: flame is large, flickers, or releases black soot: Likely cause: wick is longer than about 1/8 inch or has mushroomed. Corrective action: let the candle cool, then trim the wick flat to roughly 1/8 inch with a wick trimmer. Remove the trimmed debris before lighting. If the flame still smokes after a proper trim, stop burning and check for a draft or debris in the wax.
- Symptom: wax tunnels down the center and leaves a ring on the glass: Likely cause: the first burn was cut short, or the wick was trimmed too short and the flame cannot melt to the edge. Corrective action: trim to 1/8 inch and burn long enough for the melt pool to reach the edge, usually one hour per inch of diameter. Do not trim shorter than 1/8 inch to compensate. If tunneling persists after two full reset burns, stop trimming and choose a wider, multi-wick candle instead.
- Symptom: wick keeps leaning or drowning in wax: Likely cause: the wick is off-center or the wax pool is too deep for the wick. Corrective action: trim flat, then use a wick trimmer to nudge the wick upright after each burn while the wax is still soft. If the wick falls over repeatedly, stop using that candle. A wick that will not stay upright after two trims is a sign to replace the candle, not to cut it shorter.
Tools that match this routine

Wick Trimmer - Votive Candle Discovery Set: The Malibu Apothecary Votive Candle Discovery Set uses a coconut and soy wax blend with a cotton wick in 2.5 oz votives. Small votives benefit from trimming before every burn because a long wick overheats the small wax pool quickly.
