When your torch or refillable lighter starts sputtering, a can of butane gets it back in action. Neon butane is made for refilling lighters and butane torches, so you're not tossing a lighter every time it runs dry. Keep a can at home next to your dab torch or favorite refillable lighter, so you're never stuck without a flame. Before you refill, bleed the old gas out of the lighter and set the flame to its lowest setting. Hold the can upside down, press firmly in short bursts, then wait a few minutes before lighting so the fuel can settle.
