Very very odd for porcelain to etch...It may not be etching..It may be smudging caused by the polishing powder. I would try another powder

Justin,
That looks and sounds like a calcite based stone. However, I would suggest testing a piece of that stone to get a better understanding of what it is and how it reacts. You could also try MB-12 wet to dry. Just my thoughts!

I tried one tile with some marble polish it took out the etch marks but it doesn't seem to be as shiny as the original it's not bad I'm wondering if going all over the floor would blend it better instead of them having to tear it out. Also the polish l splatter leaves etch marks as well.
