Hello, I have attempted to clean some CE4 clearos I have, I just rinsed with hot water, let dry, and then filled with e juice. I even let it sit for a few minutes and made sure the wick was soaked, when I go to take the first drag I have a number of issues. Sometimes its hard to draw, it will gurgle some times, and there is little to no vapor at all no matter what I do, I have no idea what the issue could be, any help?
