I know I can expect etching on my marble island counter top, but I never anticipated issues with my Brown Antique granite counters.

I had localized all acidic operations to the granite perimeter to minimize etching the marble, although we have of course already christened the marble repeatedly. I expected that and have taken it in stride.

However, this morning, I see what looks suspiciously like an etch ring on the granite next to my sink. Nothing I've tried budges it.

Anybody have this experience? Did I inadvertently manage to select an etchable granite? I thought I had read that Brown Antique was pretty impervious to anything.

Perhaps I need to move all acids back to the island and go with my first impulse of deliberately etching the entire island to embrace the patina.
