I have drilled 3 small holes equal distance apart where the ring grove is and like Dick said it takes a couple of extra hands but just use nails or small punches and push in all at the same time and it will push the snap ring in, lift and wiggle the spout and it should come off, I also use oven cleaner mixed with a little warm water and slosh it around in the bottle, that will knock the gunk loose ...Frank
