A regular drying rack will not sufficiently dry a baby bottle. Most of them have very short posts or lack posts completely. A baby bottle drying rack will have drying posts of multiple heights to accommodate all types of bottles. Baby bottles should be dried vertically to avoid water collection. When a baby bottle is dried on its side or at a harsh angle water will accumulate and can cause mildew and staining. This is one reason it is so important to have a bottle specific drying rack. They also have space specifically for the smaller parts of a bottle such as the nipples and rings. On a regular drying rack, you will eventually have to dry these items in the silverware area. This can cause water to accumulate and cause improper drying. A proper baby bottle drying rack will allow your items to fit well for optimal drying.
