Had to get a new one, after my previous one started leaking. With the first one I'd found that the screw bit at one end and the nozzle at the other could both be detached, which made cleaning the tubing marginally easier. On this one, both are very firmly attached, so the openings at both ends of the tube are extremely narrow and it's hard enough to get anything down there at all. I managed to get a bit of cleaning cloth on the end of a wire in, which cleaned about three inches at one end - then the cloth came off the wire and is now stuck in the tube. Does anyone have any bright ideas please?
