The carts come apart into 3 pieces, when my cart wasn't really giving out much anymore, I took it apart and folded some papers into long thin sausages and just pushed them into and through any crevices and tunnels until there was nothing left, a bit of heat from a lighter helps. I managed to make about 8 nice little sticky rollies even after my cart looked empty. The best place was definitely the downpipe that connects to the mouthpiece, loads of leftover oil in there.
