First of all, thank you for your website and all of the great information! We recently moved into a new home that has honed black granite countertops in the kitchen. We were told that they were sealed, but we have NO idea by who, when or which product was used. We were given no instruction on care and it seams as though we have might have etched the granite (it's lighter) around the sink area by using bleach to clean other items(although I have read what you have said about the fact that bleach should not hurt the granite). A bucket was set on the counter top and we now have a 10 inch ring where it sat as well as some "splash" marks. We are struggling with those marks made by the bleach bucket and the overall dull finish, water spots and general difficulty with keeping our counters looking clean. I am planning to purchase your MB-6 color enhancer. What else do I need? What can I use daily to clean the counters after the application of the MB-6? Should I do anything to clean the counters before using the MB-6...such as MB-11? Any and all help is greatly appreciated! Thank you!

 

Dear Jodi:

Obviously the original color enhancer that was applied by the installer is a product sensitive to chemical activity.

MB-6 is a tough cookie, but, while it was successfully tested against tghe most common acidic substances, we nver tested it against bleach. After all, it's not a chemical that could be considered popular in a kitchen...

Before applying MB-6 the previous product must be thoroughly removed with the use of a good-quality honing powder. But you'd need a power-tool for that. MB-11 might do too, but it's going to be a huge chore doing it by hand!

For routine cleaning, MB-5 has been tested as the perfect "mate" for MB-6.
