Matt and I were talking about Zippo lighters a while back. Later on Matt did some research on converting a Zippo to burn isopropyl alcohol. One site suggested it could be done with switching the wick out. Other articles suggested it couldn’t be done. Well Matt wanted to know why exactly if would not work.
Recently we picked up a Zippo at our local hardware store for $10.99. We used 91% isopropyl alcohol. Do not bother trying to use 70% isopropyl because it will not work. You must use the 91%. Everclear at the liquor store would work as well but it is a lot more expensive.
The original Zippo wick was removed using some hemostats. Needle nose pliers will work. In this case the wick was pulled out the top. It would be easier to pull the Zippo wick out from the bottom. To do this you have to take the lighter out of the case and remove the felt bottom like you would do if filling it. Remove all the cotton using pliers or similar. Behind the cotton is the wick and you can remove it from there.
Waxed Hemp Candle Wick Test
The first replacement wick Matt tried was made from the waxed hemp wick we use for making bug candles for the patio. He quickly discovered that the wax kept the alcohol from absorbing so the lighter would not ignite. Perhaps if the wick were just unwaxed hemp, the results would have been better.
Old White Cotton T-Shirt Wick
As a farm wife I love creative uses of white cotton t-shirts once they reach the point where they need retired. Matt and I go through a lot of white cotton shirts working outside.
For the wick, Matt just cut a small strip of cotton and twisted it up to make a wick. It looks really big. You could braid a few thinner pieces together for a wick that doesn’t flop around as much.
This wick seemed to absorb the alcohol a lot better than the waxed hemp wick did! It would light occasionally.
Making the wick hole bigger
Matt drilled out the wick hole with 1/8″ drill bit. This allowed for better flow of alcohol into the wick and better ignition rates. The problem is that drilling out the wick hole broke the arm that keeps the Zippo lid closed. There is no way to go back to using a Zippo wick again once you take your conversion this far.
So can it work?
Technically, yes, you can convert a Zippo to burn alcohol but the drawbacks of doing this are great enough that we don’t feel it is really worth it unless you have to do it in a survival situation.
