Letter 10080 Acid stain on black granite    I have black granite(nero assoluto)flooring in my powder room. It is a new home. Last week someone came to repair some scratches on the pedestal sink. He placed the bottle on the granite floor. I think the solution was an acid based solution. I noticed this week that there is a white ring on the floor which was the result of him placing the bottle on the floor. I tried to remove it with a light abrasive cleaner(Vim) It does not come off. Can this stain be removed? If yes, how? It is very noticeable. A response would be greatly appreciated.

Did anyone respond to your inquiry? It really looks bad. Thanks, David M [last name deleted for privacy due to age of posting] - Pensacola, FL
