My car's been in the garage for a couple of weeks and it's come back today with an air freshener in it. I have just driven it having taken the air freshener down but the hideous chemical smell has got in my mouth and my eyes are itchy. I'm not even particularly sensitive to this sort of thing. It's raining so I can't just leave the windows open. Is there anything that'll absorb the smell - a pot of bicarb or something?
