Back to school season means new lunch boxes for the kids. When looking for a new lunch box, think fabric bag. A fabric lunch sack replaces throwaway brown paper bags, is more durable and can insulate food to keep it fresher longer. Plus, it's machine washable. Since mold, mildew and other germs can grow in a reusable lunch bag, be sure to wash it at least once a week to keep those germs away and keep the bag fresh. If you insist on using a hard plastic lunch box, use a chemical-free sanitizer like CleanWell, which will kill 99.9 percent of germs but is free of harmful triclosan found in most sanitizers today.
