Many bottles have a thinner design with a slim neck. These are a style of water bottles that may be convenient to carry around and drink from, but it is a nightmare to clean without the right brush to use. If you are trying to blindly clean by shoving a sponge in there, you will get nowhere. Get something with a long barrel and a sturdy handle, and you will be able to clean those up without any problem.
It can be dangerous to leave parts of bottles unclean. Your water bottle comes into contact with your mouth, and all of the bacteria that lives in your mouth will transfer over to it. That is why you are not supposed to reuse plastic bottles because they can be a hotbed for bacteria to grow. You do not want to simulate that in your own reusable bottle, so get yourself the right bottle-cleaning brush.
