Florance asked: How do I fix damage from toilet bowl cleaner? Toilet bowl cleaner containing hydrochloric acid was spilled on dark granite and resulted in a spot that is lighter than the rest of the counter, almost a bleaching effect. Is there anything I can do to darken it?
Once granite has been “etched” by acid, the damage cannot be repaired. A professional may be able to refinish or “rehone” the granite, but there’s nothing you can do to restore the spot on your own. We recommend finding a reputable pro by contacting either the installer or manufacturer.
