Hi everyone! Hope you all are having a good day! Quick question, how often should one clean his or her tank? I bought the Smok TFV4 last Saturday night I'm about ten tanks into the quad coil it's working great I'm vaping a variety of juices and getting good flavor from all the different juices. I was thinking of cleaning the tank once my coils is pooched! Thought? Suggestions? Should I clean it before then? That would mean I'd have to remove the coil if it's fine to clean every coil switch I'll just stick to that thanks!!
