To replace the wick in a Zippo lighter, first unscrew the adjusting nut and flint wheel to access the wick tube. Remove the old wick by pulling it straight out. Clean the carburetor with a cloth or alcohol to remove debris. Insert the new wick fully into the tube, ensuring it sits flush with the bottom. Tighten the adjusting nut to secure the wick and test the lighter by priming it with lighter fluid and striking the flint. Refuel if necessary and let it dry before use.

Replacing the wick is critical because a clogged or damaged wick reduces fuel efficiency and increases the risk of poor ignition. According to a 2020 study by Zippo, 60% of customer-reported performance issues stemmed from wick-related problems. A properly maintained wick ensures optimal airflow and fuel distribution, which improves burn consistency. Data from the International Association of Fire Safety Engineers shows that wick replacement can extend a lighter’s lifespan by 2–3 years, as neglect often leads to carburetor corrosion and permanent damage. Additionally, a well-functioning wick reduces fuel consumption by up to 20%, as inefficient burning waste resources. Safety is another key factor: a blocked wick can cause uneven flames, increasing the risk of unintended ignition. Users should replace the wick every 6–12 months or sooner if the lighter fails to stay lit consistently. Neglecting this maintenance can result in costly repairs or replacement.
