I hide lavender dryer sheet in my car. It's subtle and not so strong. After a road trip when we eat fast food in the car, I air it out, clean it and spray Fresh scent Fabreeze. I hate smell of fries in the car.
I usually leave scents alone. Just can't handle them anymore. Give me a headache. Soap and laundry is scent free too. My skin is sensitive as I get older. No perfume or cologne in the house either.
