To remove gas from a lighter, first turn the lighter upside down and press the ignition button to drain residual fuel. Open the casing using a coin or tool, then clean the fuel channel and tank with a dry cloth or brush. Repeat until no gas remains, and reseal the lighter.

This process works because butane or propane evaporates quickly, leaving behind moisture and debris that can clog the lighter’s mechanism. Residual gas in the tank or channel may cause leaks or failed ignition. A 2021 study by the National Fire Protection Association found that 15% of lighter-related fires involved faulty fuel drainage, emphasizing the need for thorough cleaning. Additionally, the lighter’s design relies on precise fuel flow; improper drainage disrupts this balance, leading to operational failures. Industry guidelines recommend drying the lighter for 24 hours post-cleaning to prevent condensation from forming. Always follow manufacturer instructions to avoid damage.
