bad smell in the mazda 3. just since one week this summer when it sat for a week not driven. have done professional cleaning of the interior, and have cleaned air filters. still a smell like mildew ? what to do ? thanks
Pour and solution of anti-bacterial liquid cleaner (Lysol, Pine Sol, Odo Ban ect) and water down the windshield. Let sit overnight. Rinse. That should kill the mildew in your ventilation system. If it helps but doesn’t quite clear it up, do it again.
