How should I clean stone surfaces prior to applying sealer?
How do I clean my Natural Stone tiles and slabs?


  Clean stone surfaces with a few drops of neutral PH stone cleaner
  available at retail stores or at your local tile and stone dealer, or
  a mild liquid dishwashing detergent and warm water. Use a clean rag
  mop on floors and a soft cloth for other surfaces for best results.
  Too much cleaner or soap may leave a film and cause streaks. Do not
  use products that contain lemon, vinegar or other acids on marble or
  limestone. Rinse the surface thoroughly after washing with the soap
  solution and dry with a soft cloth. Change the rinse water frequently.
  Do not use scouring powders or creams; these products contain
  abrasives that may scratch the surface.
