Hi all. Been a while since I've been here. Hoping someone can help me out. We purchased a 2011 Grand Cherokee back in October. The previous owners smoked in it, and I'm having the toughest time getting the smell out. It was detailed when we bought it, which helped a little. It has leather seats, so not sure what if anything can be done about those. I try to let it air out for several hours a few times a week, but that doesn't seem to be doing much. I also febreeze the ceiling and carpet a few times a week as well. Short of replacing the ceiling like I've read online to do, anything else you can suggest I try? My dad was telling me there should be an in-cabin air filter I can change that will help, but it is nowhere to be found in the manual and DH has looked online and can't find any info on it. I'm pregnant and due in April, and the smell sometimes aggravates my allergies, so I'm wanting to try and make it fresh in there before LO arrives.
