you are probably heating it up enough with your breath to soften the residue. I think what is happening is the mouth piece gets gummy inside the tube very quickly, when you close it down and it cools, the residue hardens and sticks the tubes together. Mine started feeling sticky the first day. I have since cleaned the inside of the ss tube on the mouth piece every few loads with a dry q tip, with some of the cotton pulled off so it will fit inside the tube. I have not had my mouthpiece stick since, and even have had it shoot off the pax a few times when popping up. I have also been removing it as the pax cools, and again have not had any kind of sticking or drag. I imagine a twisted up paper towel would also work in a pinch with no q tips around.
