We normally get a lot of build up due to the water in our area in our babies hot flask and his sterilizer which is tough to get rid of. After using this as recommended on the back, after cleaning the items it comes out like brand new. You don’t have to use much of the product so do last a long time. It does have a strong smell but the bottle is well so there’s no leakage or smell coming through when storing. It’s good value for money and the size means you get plenty of uses out of it .
