Kids heading back to school? Keep those backpacks, book bags and laptop cases looking new with a dry-cleaning or soot-and-dirt removal sponge (available at hardware stores and home centers)! Working outdoors or over a garbage can, rub the dry sponge over the soiled surface of the bag to “erase” dirt fast. For heavier stains and grease spots, try using Spot Gone or Grandma’s Secret Spot Remover, following the directions on the bottle.
