I’m not sure what is happening to my granite. How can I fix this?

    When did it start? How long has it been going on?

    Is this a new counter and you just started using it or have you been using it for a long time and it just started happening?

    I'm betting your sink is leaking. There are probably no clips between the rear of the cabinet front and the sink. The steel on the flat of the divided sink is flexing, allowing dirty sink water to get sucked between the sink flange and the bottom of the top through capillary action.

    Open your dishwasher and see if you see a 1/4" yellow line heading toward the sink. That would be a reinforcement rod that's going to rust and burst your countertop. I get a call a week for this and fix a couple every month.

    Drop the sink and take a Bernz-O-Matic to the stone until it's dried. Clean the sink flange and stone bottom, silicone, and strap, not clip or block, your sink in place. May as well replace it with a single bowl while you're at it.
