      i have a colored kohler toilet.(mexican sand )it now has a blue stain i can’t remove, from using a continuous clean toilet bowl cleaner. does anyone know of a product that will remove this stain without damaging or discoloring the porcelain.

      Hydochloric acid will remove the brown colour from water running down the bowl, might do the blue too..
