Everybody knows the Zippo lighter. That piece of rudimentary engineering has written history. However, even if the company offers a lifetime warranty, that doesn't mean it will function properly until the end of time without any maintenance. And regardless of that, the costs of shipping it to Zippo and having a new one shipped back in case of default often costs more than going to the nearest shop and buying a new one.
What you need is a Zippo wick, flint and gas. So far we're talking very low cash, as they are cheap and last a lot. The gas is apt to drain quickly, but the wick can last a year and the flint as well. It also depends on how often do you use it.
Open your Zippo and take out the main body from the cover. On the bottom you will notice a cap. You can use the edges of the Zippo metal cover to unscrew that cap. There's an arc attached to the cap, because the metal tube that it covered is the housing of the flint. Put one piece of flint inside. You can put two, but chances are the friction will be too strong for the stone to actually spark it. Screw the cap back on. You're done with the flint. It's as easy as that.
Next, take out the wadding. It fills the entire body of the Zippo lighter. Its role is that it imbues with gas and stays wet for a long time. Be careful when you take it out, you will notice the wick is wrapped all around it.
