Your car interior collects more dirt than most people realise: food crumbs, dust, pet hair, and fine debris from shoes. Using a vacuum cleaner for the car at least once every two weeks helps keep the cabin fresh and prevents buildup. If you have kids or pets, consider doing it weekly. Focus on seat creases, floor mats, and areas where dust tends to settle.
