I was just thinking about cleaning my carto's and thought to myself, maybe I should just change the filler. I've seen different types and wanted to know if anyone had a good suggestion. I think we all want the best taste out of the liquid use. I don't really think the regular poly-fill is the way to go. I've seen the tea bag thing, blue filler, and a few others. what did you true, did it work, and hows does it effect your juice?
