The ME is chemical-free and used dry. I know many use a cube of ME and then dip the stylus into it and this may be the best approach for those with poor eyesight and unsteady hands.
However, the approach that works best for me is how I've seen DougDeacon use it. That technique uses a thin piece glued to a toothpick like a brush. The ME is gently brushed down the sides of the stylus, obviously not back a forth. I don't think there are any fibers left behind, but I always use my soft stylus brush before and after the ME. This method has kept my XV-1s stylus clean and shiny.
