<whisper voice>You might could sweeten the ejection charge a tad to ensure you get the laundry out. You can put a pinch of 4F on top of the ejection cap, and place a ball of wadding on top of that to hold it in. I doubt anybody over here would make a federal case out of using this trick, but be careful who you share this with - you don't wanna attract the interest of the internet cops </whisper>
