Our cars are like a second home for many of us, so why hang artificial air fresheners from the rearview mirror? These fresheners, along with plug-ins and sprays, are loaded with chemicals and often with phthalates that contribute to unhealthy air quality. If you want to keep your car smelling fresh, reach for charcoal. Charcoal is a natural odor neutralizer, and it's long lasting, too. Fill a large tea strainer with pieces of charcoal and place it in the cup holder or hang it from the rearview mirror. The real smell of clean is no smell at all -- not "pine."
