I transport a lot of stinky pre-teen boys in my car. I also have a puppy dog that loves to be my co-pilot. Between them and their food, equipment and shoes (why on earth do they insist on taking off shoes in the car??) there is a wretched scent that lingers long after they have been dropped off at their respective homes. Febreeze doesn’t always last, so I have resorted to potpourri in my console. I keep it a sachet (they are in the wedding section in most craft stores) and freshen it up time to time. I have learned that the more earthy, musky scents cover better than their floral counterparts.
My current blend includes
Earl Grey tea blend (loose tea)
Chamomile
Mugwort
Comfrey
Cardoman pods
Cloves
