From the little information that you have given I am supposing the problem you have is a rusting on a white/grey/ black speckled granite.  The easiest method, whether for walls or floors is to apply a particular acid product. The two that I know of is from Akemi or Lithofin.  The Lithofin one is called Bero and is made to remove the yellowing caused from irons in the stone oxidizing or rusting.  You spray it on, let it sit 24hrs, come back the next day and power wash it clean.  Always do a test prior to doing such a job

Hi I went to look at a outside of a building that had large peices of granite on it. They were stained like a yellowy color. What would be the best way to restore them?
Thanks in advance.
