I've seen a number of videos and how-to's showing how to refill a cart. They usually involve taking the stuffing out, putting liquid in, and putting the stuffing back in.
I've found that this ends up killing the wicking action because I think the act of taking the stuffing out degrades its consistency. But, if I leave the stuffing in, drops of liquid fail to make it down into the rest of the stuffing.
So, here's what I've found works very well for me: I don't take the stuffing from a fresh cart out - ever. Instead, I rest my dropper on the inside of the cart and let the liquid "flow" into the stuffing instead of dripping big drops onto it. This seems to let the liquid saturate the stuffing easier. They key is to let the stuffing stay exactly where it is and disturb it as little as possible.
When I do this, I get the optimal wicking performance.
