I was at a Porsche Club event today and I mentioned to the local Adam's dealer Darryl that the previous owner of my 2008 Cayman was a smoker (the car had been detailed prior to delivery to me) so the smell was disguised for a couple of weeks. Darryl grimaced, but told me that I needed to clean all of the carpeting first as that is where a lot of the "contaminants" are. I won a door prize from him and he gave me a spray bottle of his "Carpet and Upholstery Cleaner" which I will apply tomorrow. While I was standing there, his associate (I will get her name), told me about a previous employee that "smoked like a chimney". She told me that the remedy is to cut an apple into quarters and place a piece in each quadrant of the cabin and close it tightly for 24 hours (I am doing that now). To bad that smoker info can't get into a Carfax report!
