I keep having this issue where I open my cart to refill and the foam is stuck to the atty. I got a new cart and it still did it. It frustrates me because I get the juice all over my fingers and putting the foam back in is a hassle and it gets all wadded up. I got a different atty and it did the same thing. What causes this? Is the atty dry or something? I never had this issue before. Also do you know of any sites that sell carts with more foamlike foam rather than cotton like foam? Maybe that would help.
