There’s just something special about getting behind the wheel of a brand-new car and taking in that clean, fresh leather and polish scent filled with endless possibilities. Unfortunately, that new car smell doesn’t stick around forever. No matter how hard you try to keep things tidy, your car eventually starts to smell like a mix of spilled coffee, takeout food, a wet dog that recently went for a swim, or, god forbid, baby diapers. When our cars start smelling funky, most of us turn to the usual fixes: air freshener sprays and those little pine trees for the rearview mirror. But it might be time to ditch the aerosol spray in favor of a natural, do-it-yourself solution to banish those unpleasant car odors.
