I only use CE2 customizers and several were starting to go down hill, poor draw and burnt taste. Having taken several apart when they got that way, I came up with a way to somewhat clean them. Take a syringe, fill with water and squirt the water thru the threaded end. Also it will help to loosen the grit in the little cup that sets just sets below the coil with a needle. The grit is what mainly causes the poor draw and the grit also adds a 'NICE' flavor to the juice. After doing a couple, they are working fine, not quite as good as new, but a lot better than before cleaning. The main thing a bout this way of cleaning is that no juice need to be removed before cleaning. Just clean, blow a little bit on the coil, then vap.
Been using the same CE2's for over a month now, like using these better than trying to drip and refilling carts all the time.
