18 months ago, we had a Tropical Brown granite kitchen counter top installed and sealed. It has been cleaned 2-3 times a day with water and a small amount of Palmolive dish detergent, then squeegeed dry. Recently, in a high use area, several small areas(.1 to .3 inches across) of etched surface have appeared. They correspond to areas above clear, white-ish crystals in the stone. When viewed at an angle, these areas stand out sharply compared to the polish of the rest of the surface.
Can anyone please recommend a plan to:
1. prevent further development of the existing etched spots
2. prevent development of new etched spots.
3. restore etched spots...maybe seal/epoxy/repolish?
