Dunno; I haven't had a problem with lint in the striker. I don't smoke anymore (or else I'd still EDC a Zippo), but I do take it out and light it every couple weeks as a test. Perhaps that is enough to keep it clear. I also have matches in my desk drawer, a Sparklite in my PSK and another (zip-tied) Bic down in my BOB, so I'm not too worried about being able to make fire when needed.
