Maurizio, I recently cleaned the faucet in my bathroom with a product that removes calcium carbonate (the water here is VERY hard) and I sort of ruined my green granite counter top. Around the faucet is all white, as if I had bleached it? Would this product MB6 help to at least hide the white spots? I don't really want to replace the whole counter top because of this. Thanks for your help, Eliane

 

Dear Eliane:

There's no need to replace your countertop. The real solution would be to remove the faucets and then have a professional stone restoration contractor slightly re-grind (hone), the damaged area and then finish the job by re-polishing with the right abrasive means to blend with the rest. If for some reason you can't resort to such a solution, if when the damaged area is wet it goes (temporarily) back to its original color, MB-6 will give you the same effect permanently.

And the next time, when you have to remove hard-water deposits, use a razor blade to remove the worst and then finish the job with a heavy-duty alkaline cleaner with chelates in its formula rated “for natural stone” like MB-3.

May I ask you now to please read and e-sign our Statement of Purpose at: http://www.marblecleaning.org/purpose.htm?

Ciao and good luck,

Mauri zio Bertoli
