Butane lighters can be incredibly difficult to refill since many of them are temperamental and need to be properly cared for. The biggest problem with butane lighters, in regard to the refilling process, is the excess air that remains in the tank once the butane is burned away. Luckily, there is a specific process to follow to ensure your butane lighter sparks time and time again. Once you run out of butane, first close the tank by adjusting the burner valve (located on the bottom of most lighters) to the “negative” position. Next, use a small pin, needle, or lighter tool to push the inlet valve down, which will release any extra butane and/or air still inside the tank. Feel free to try to spark your lighter at this point – you should see no flame but in doing so will also clear out the ignition system of any excess air or butane. Now you can refill your lighter with triple refined butane, this is very important. Triple refined means the butane has been filtered at least three times, which removes any impurities, allowing for a clean burn and a steady, consistent flame. Any other butane may clog your lighter. Once you refill your lighter, you can now adjust the burner valve to “positive” and try igniting it. Be careful, since you may receive a big flame at first, which is good because it will burn off any left over dirt or dust still in the ignition system. Now you can adjust the flame to your specific preferences and continue to enjoy your cigars.
