IMO, There is a huge difference between having to clean a batt end that has been submerged in juice or having to just dab the center post with the tiny corner of a paper towel.
What I mean here is...... By Plunging from the mouth end s-l-o-w-l-y, you can see the juice coming through the end hole (the first bubble of juice) before it actually spills out of the end hole and floods the grooves, threads, etc...
