Muriatic acid

   I set a a glass down my grantie countertop which is Black Absolute, polished, after I rinsed the glass in the Kitchen sink. The glass had a diluted solution of muriatic acid in it that was used to clean some brick on the outside of the house. I though I had rinsed the glass well, but obviously not well enough. When I picked the glass up about an hour later a ring was left that has the appearance of honed stone, more grey in color. The stone still feels smooth. but now looks like the polished finish is gone. It's smooth, but not as smooth as the stone adjacent. Can this be polished out?
