To someone that said use 100 percent cotton to make flavor wicks with and some guy that did a video on you tube that used baking soda and vinegar to clean his atomizer. That worked great to clean a really bad coil. And to all of you on this forum. Without this place I would not have known great places to get liquids. What clearo to use and so much more. This has gone from not wanting to smoke to a wonderful hobby that I am really enjoying. This community is better than any other I have experienced.
