The previous owner of my 90 GT was a smoker. I can't freakin' get rid of the smell! Over the past couple months I've tried some "febreeze" type stuff from Renuzit but that hasn't worked. I've tried leaving the inside of the car all open for a while but that hasn't helped either. Recommendations please??

The vinegar smell will disapate after neutralizing the odor. This is similar to putting baking soda inside you refridgerator to remove food odors.
