I use isopropyl alcohol to get the gunk off but there are always a few lines where the water has evaporated and left hard water salt lines that I cannot clean. I got some calgon for my washing machine to remove limescale from hardwater that I have. It cleaned my bong like new. I used a whole tab but I reckon half or quarter would do fine.
