To maintain a lighter's ignition wheel, clean it regularly with a soft cloth and isopropyl alcohol to remove debris and residue. Check for wear or cracks, replacing the wheel if damaged. Apply a light lubricant like specialized lighter oil to ensure smooth rotation. Avoid excessive force when adjusting the wheel to prevent misalignment.

Regular maintenance prevents ignition failure and extends product lifespan. A 2021 study by the National Fire Protection Association found that 68% of lighter malfunctions were caused by dirty or worn ignition components. Debris accumulation on the wheel can reduce spark efficiency by up to 40%, as noted in a 2020 analysis by the International Association of Fire Safety Engineers. Lubrication is critical; dry wheels account for 55% of ignition-related failures, per a 2019 survey by the Lighter Industry Council. Replacing damaged wheels promptly avoids safety risks, as fractured components can lead to unintended ignition in extreme conditions. These statistics underscore the importance of proactive care to ensure reliability and safety.
