Also, that new car smell....well it is really the plastics and synthetic fiber that are out gassing, some really toxic things too like formaldehyde and cyanide. I think the reason that for some folks it is a good smell is that they like having a new car. I hear antifreeze tastes sweet too, does not mean I want any in my koolaid. There are so many artificial scents out there that are really irritating...I don't need my dish soap to smell like citrus fruit or mint, I don't need my laundry soap to smell like "fresh air" either. Again natural scents do not trigger my allergies and the best air freshener is fresh air. In my old job I used to have to do home visits to some really stinky homes but the worst was when I had to go to this place where artificial vanilla was puffed into the air every fifteen minutes, and she chain smoked, what was her major complaint, her asthma was not getting any better despite the doctor upping her meds, and she had children with asthma so bad they needed nebulizers every day...was she open to just unplugging the room odorizer, no, lets not go there when I suggested she smoke outside. It was so bad I would only go into her home if I could sit by an open door...she did not like that either, it diluted the vanilla scent. OYE some folks!
