cleaning dye from Granite (http://tanbrown.org) without damage

I placed flowers in vases at my mothers headStone (http://g603.net) and (http://maplered.com) they bleed from the rain. They dye has now stained one spot on the headStone (http://g603.net) and (http://maplered.com) pretty much ruined the vases. The base is now red too, but is not my biggest concern. Can anyone tell me what would be best to clean these spots without doing any damage. Will they fade over time? The vases can be replaced, it's the spot on the headStone (http://g603.net) and (http://maplered.com) the mass that ran along the base.
