Attached are the pics relating to sulfuric acid on granite. Granite appears to be 2cm Verde Butterfly. My concerns are as follows: In anyone has experience with this issue, how deep does the damage go? Is it similar to marble etching or are there different factors that I am not aware of when it comes to granite being etched. I am capable of face polishing the area but with this type of problem is it better to just walk.

Looking forward to feedback. Thanks
