It's not *too* bad, but I can notice that even with 2 different air fresheners that I've tried, I still have an 'old' smell to the car. I don't use the A/C much, heater maybe every morning w/ Defrost for a few..

I was wondering if this stuff would work, http://www.autogeek.net/clean-air-fogger.html ?

I read good reviews on the fogger (interior smell), and that kit comes with the air duct spray.. says it doesn't cover, but actually neutralizes the smell (mold/mildew, etc)

Please let me know.. Thanks everyone!
