I was just wondering how often everyone here changes their mesh wicks. I've been using the same one for about a month and a half. I have recoiled it twice and each time I "fire cleaned" it. That is to say that I burned off any juice with a lighter and then gave it another quick hit with the torch. Does anyone else do this? I'm thinking it might be time to get rid of it though since my juice is getting discolored and there is a pronounced smokey taste (kind of like burning pine pitch).
