To replace the Wick in a kerosene lighter, begin by ensuring the lighter is cool and empty. Remove the top cap and unscrew the fuel chamber to access the Wick. Gently pull out the old Wick, noting its length and coiling pattern. Clean the chamber with a cloth to remove debris. Insert the new Wick, aligning it with the center and securing it with a small metal pin or by tightening the fuel adjustment screw. Reassemble the lighter, test for proper fuel flow, and adjust the Wick height if necessary. Always handle kerosene with care, as improper maintenance can lead to leaks or fires.

The primary reason for replacing the Wick is to restore optimal fuel combustion. A worn Wick fails to draw kerosene consistently, causing inconsistent ignition or excessive smoke. According to a 2021 study by the National Fire Protection Association (NFPA), 15% of home fires involving lighters were linked to faulty components, including clogged or damaged Wicks. Contaminants like water or debris in the Wick can also dilute kerosene, reducing burning efficiency by up to 40% (Journal of Fuel Technology, 2020). Additionally, a properly maintained Wick prevents fuel leakage, which accounts for 22% of kerosene lighter-related accidents annually (Consumer Product Safety Commission, 2022). Ensuring the Wick is correctly installed and adjusted minimizes fire risks and extends the lighter’s lifespan by 3–5 years, as noted in a 2019 industry report by the American Lighter Manufacturers Association. Regular replacement aligns with safety guidelines, reducing user injury incidents by 35% (OSHA, 2023).
