I'm still a bit new to all this and can't seem to find anything in my searches, my CE4 was working fine then I got the burnt taste, what do I do here, I had just filled it to the brim and now it's no good. Do I discard the whole thing with liquid still in it or is it safe to pour this into my new clearomizer, it seems quite easy to be done but I don't know if anyone else does this or if it's even safe safe to reuse.
