Carl Huang said: Guys, zippo wick aren't made of the same material as the one in our attys. I burnt the atty one with a lighter and the shiny white appearance is restored and the gunk gone. Whereas the zippo wicks with the cotton sheath removed melts into a tiny transparent ball. Not sure what are they made of though. The packagin of the zippo wick I bought seems pretty legit. Anyone has got spares lying around for an independant test?
The zippo wicks have a cotton shell that will burn, the inner wick is silica or fiberglass, not sure which, however, I tested it and it does not burn. Thats why the instructions say to burn off the cotton shell first. If you want another source for wicking material you can use an old ce2 cartomizer and take the wicking from that or heavensgifts.com sells replacement wicks under their do it yourself section on their web page.
