In warmer months, many of us open windows in our home to flush out airborne toxins. It's called cross ventilation, and a breezy day will help to keep indoor air quality cleaner. But think about your home-away-from-home: your car. Park your car outside and open all the windows to flush out the odors and toxins building up inside. Remove floor mats and vacuum them well; leave them out so the sun's rays deodorize them naturally. And pop the trunk while you're at it: De-clutter to lighten the load and improve your car's mpg.
