Not necessarily.
But ordinary perfume cannot be used. Firstly, the bottle cannot be attached to the car. Second, the perfume will easily deteriorate under light and high temperature. A real waste for a branded perfume.
We also have car perfume in our car, but we don't usually use it.
However, leather parts sometimes give off an odor, especially in new cars. At first we bought activated carbon to absorb odors, then went to a car dealership to get odor removal service, but the results were not very satisfactory.
In the end, I decided to put flowers on the car, and it turned out to be a good idea. You can choose flowers with a long-lasting scent, such as ginger, jasmine, lily and water lily flowers.
