last week I dumped maybe a half pint of gasoline inside my car as I was taking gas to a friend who ran out along the road...long story short...I've tried about everything to get the smell out of the carpet, the smell is just about gone but when I turn on the heater the smell gets stronger...any idea how I can remove the smell...it was suggested that I replace the carpet but a 20 year old car but might be tuff to find carpet , not to mention what the price might be
