Water ring mark in granite...


Hello...we have "Black Mysore" granite(?) slab kitchen countertops. Recently a mixing bowl was washed and evidently not completely dried and set upside down on the counter. Now I noticed a darkish ring where the lip of the bowl sat on the countertop. The granite was sealed a week after instalation about 8 months ago by our contractor. I've read mutilple websites regarding granite care and am now feeling more confused than ever. Can you please help me get rid of this ring? Thanks for you time, Leigha
 
Dear Leigha:
I never heard of Back Mysore granite. Maybe it's black "granite" that was quarried in the southern part of Mysore and Bangalore disctricts in India.
Be that as it may, there's no such a thing like a black "granite" that could be possibly sealed. They may have applied an impregnator to it, but it doesn't mean that the stone got sealed. In fact, all black "granites" I know of don't absorb anything and don't get stained, either.
That duly said, going with your report the bowl was only wet with water. If any of the water ha ever been absorbed by the stone, the ring hat you have nw would be long gone.
It appears that it is more permanent in nature; therefore I have to think that, maybe, the water reacted in some funny way to an invisible film of impregnating/sealer that had no business being there to being with.
If that's the case, have your fabricator come back and strip the sealer. After that, everything should be all right, providing that you use the proper cleaning products to care for your stone on a routine basis.
 
If your fabricator needs assistance on how to strip the film of impregnator, have them contact me.
