On that bottle you use a "ear bulb" like the one in the below photo, or a babies nose bulb,,, very cheap at Walmart. You protect the neck label from getting wet with a piece of wax paper, or foil that is secured to the upper lip of the bottle with electrical tape. ***The tape cannot touch the label**** then use the bulb to put CLR or lime Away into the bottle ,,,swish it around, let sit,,, do again,,,, when you are happy, flush out CLR with water,,, then inset rubbing alcohol into the bottle with the bulb,,, swish,,, empty & let dry overnite.
