Brooke, are you trying to clean a cartomizer, or an atomizer ? If you are using V4L products they are cartomizers. If you get juice caught in the bottom area of the cartomizer (where the threads for the battery are) just wipe it out with a paper towel. If you are talking about the threads on the battery, Once or twice a week wipe the threads down with a cotton swab soaked in alcohol. If you are looking to clean the cartomizer itself, there are many videos on you tube that show various ways of doing it.
