How can I make a car air freshener?
user
The simplest approach to making a car air freshener is to either make the car smell nice to start with, or if it already smells bad, then make a simple product that blends with the car’s existing smell, to make it less noticeable.  Or you could blend a nice smell with an air-freshener, to boost the effectiveness of the freshener.

I saw something about putting essential oil on felt.  Do you know anything about that?
