Since I don't know the brand I went to the marble institute of America. They suggest
0000 steel wool lightly buff. But if you know who you purchased it from I would always call and ask them first.
Thank you Sherrie!
I used a pumice stone on that area only. The pumice stone must be wet so it doesn't scratch the surface. I now make it a point to wipe the area with granite cleaner so it does not build up. The pumice stone is used on toliet bowls to remove built up calcium deposits and does not scratch if used according to directions.
Thanks Rozanne! It's a lil scary, that thought, but who knows??
Thank you Juju...I see why that would be helpful & will try it!
