I used the same plug for 7 days. After 4 or 5 days I did rinse it out, but only because it looked nasty - it was still performing just fine.
I use it with a notched drinking straw. We are constantly refining the straw and the plug material. I'm not committed to any one thing except using the straw as a plug stand. After trying polyfil, green scrubbie pads, blue scrubbie pads and the buff puff (
BP), I really liked the properties of the
BP. It's single direction "accordian" property allows it to expand into the cart and channel liquid to the
atty. It doesn't get crusty or hard, like polyfil. We have been working on getting just the right dimensions. My only issue is that the
BP can get sucked into the
atty once it gets dry and refilling ANY plug system is a bit messy.
I haven't tried the blue foam yet. I've been following Eclypse's progress to see if he gets the right dimensions to stop leaking before I try it with the straw mod. (Why do the work too, when someone is already working on it? Plus, I don't have a pet store nearby and Walmart doesn't carry any. LOL)
I think if the blue foam is used with the straw, you could use a smaller, less dense piece, because you won't need the tension to hold it in the cart. Although, a couple of people have used the foam with the straw and said it didn;t work as well as the
BP - but I haven't tried it myself yet.
