Ask a Question
  • are these spots which D2 will not address?

    The CleanStone will remove hard water staining. In some cases, there are black spots that the D/2 will not be effective in removing. In this case, we suggest applying D/2 to the problem areas, and wrapping in plastic to give the D/2 a longer dwell time.
