In this tutorial, we learn how to maintain a butane lighter. There are a variety of butane lighters available, but basics for all of them are all the same. First, adjust the flame dial all the way down to negative. Then, purge the lighter using the back of a wooden match. You will hear a hissing noise as the butane and air escape. Do this until you can no longer hear the noise. You will now clean the lighter by holding a canister of air at a 45 degree angle 3 inches away, spray a few times and it will clean the lighter. Finally, fill the butane lighter back up with a good quality of fluid. Let it set for around 2 minutes and you're set!
