Jet Black countertop stain |
Article Number: 202 | Rating: Unrated | Last Updated: Sun, Jul 15, 2007 at 12:00 AM |
I have recently had a jet black countertop installed that has ring marks on it after leaving a lemon juice container on it overnight. Is there any way of removing this stain?
Dear Rick:
But that is not the point. The real point is that black “granite” should have not reacted with the lemon juice – as simple as that.
So, what happened?
Let's start by saying that the only black mercantile granite that has the legal right to be called “Black Absolute” is the one coming from
There used to be three possibilities to explain the problems that you are experiencing, which are here listed in order of probability (the first being the most probable):
In the last couple of years there's been a change in the scenario above. Another possibility has entered the scene:
4.
Certain manufacturers apply some sort of protective wax to the slabs. It is not actual “doctoring,” since there's no alteration to the color of the stone, but
the result is the same as if the slab had been “doctored” with the “shoe-shine.”
Finally, case 3 above is not as rare as it used to be anymore. At least a couple of “Black Absolute Granites” allegedly from
Having said all that, the remedy to the points 1, 2 and 4 is to remove whatever it is that's sitting on the stone surface, by either stripping it chemically by soaking it with Methylene Chloride, or mechanically, by rubbing on the stone surface a polishing compound for marble (NOT for granite!) with a little bit of water.
Case 3 is terminal.
All things considered, black granite – which should be considered among the most enjoyable materials as a kitchen countertop – has made it out my own list of recommended stones.
Until the industry will not straighten its act up by becoming serious about the classification of all the different “granites” on the marketplace and dictate strict rules and guidelines about their characteristics and implied guarantees to the consumers, my position is going to be that from now on.
