@mmehta0189, after you wash them with water leave the pump on and it'll clear the line for you. I also soak pipe cleaner with alcohol and once a week I use that to clean either side of the line then I rinse with water then leave the pump on to get all the condensation out. They also sell steamer packs at target and babies r us. I exclusively pump so I treat my pump like my other baby

Online it said clean with water once a week.. How do you clean yours?

the air lines? if that's what you are referring to, I wouldn't suggest water in lines, they won't work like they should
