1. Rinse each perfume bottle with water. Then add a few drops of vinegar and water to the bottle and rinse it again.
2. Dry the bottles with a hair dryer or something similar.
3. Arrange and group the perfume bottles according to size or color. This type of arrangement is very decorative and can be used as a work of art, which will be beautiful.
4. You can put some beautiful small flowers in these bottles, which will be more ornamental.
5. Store your homemade perfume in old perfume bottles, or buy a large bottle of the same perfume and pour it into the used smaller bottle, so that you can use it more conveniently.
6. These used perfume bottles can be placed in your garage, and some screws, nuts or bolts of appropriate size are placed in them. Of course, be sure to label the outside of the bottle with the name of the item to avoid confusion.
