This CE 4+ Series clearomizer (tank) is easy to refill and clean. It has no burning taste, extra long wicks, and no leakage. This tank is rebuildable! You can easily take it apart to clean or replace wicks.
The recommended steps for cleaning a rebuildable tank are to soak the pieces in a little everclear or vodka for 30 minutes. Swish and roll the wicks around a bit to ensure they are getting cleaned properly. Pour out the alcohol and place the pieces on a paper towel and let dry overnight.
