The wick included with the titanLIGHT™ should last a very long time if maintained properly. When the wick looks worn or wispy simply pull more wick out from the top and trim with a sharp pair of scissors. If the wick binds, you may need to remove the fuel cap and the cotton to free the wick enough to pull through. Once you’ve achieved the proper length (top of the flameguard), fold the wick over between layers of cotton balls and replace the fuel cap.
