Many questions that we receive are about granite, marble, terrazo and other stone surfaces that are etched or hazed. These are to be cleaned with special products, not our Shower Stall & Tile Cleaner or Cling N Clean Toilet Bowl cleaner. If our cleaner is not well rinsed off dark tile before drying it can leave a haze. Clean again with a scouring pad and rinse well.
Stone surfaces are made of of minerals that are sensitive to many things, acid based cleaners, vinegar, wine, soda, or even hard water.
Metal surfaces can also be stained if cleaners are allowed to remain on the surface for a long time.
