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?
user
Yes, I understand what you mean.  You’re thinking about rubbing essential oil on a material with a relatively coarse surface, then placing the material in the car.
assistant
Yes, it's the same as the air fresheners you get in store, right?
user
Hmmm, no, I’m not sure about the effectiveness of this method.  You could try it though.  That would involve placing the substance somewhere in the car where it’s in contact with the air.  It could then absorb car smells, or it could lose its scent over time.

Thanks for the help!
