Etched Specks on Countertop before Honing
Water spots or etched rings on counertop surface.
Marble, travertine, onyx, limestone are all these stones on a calcite basis, and therefore unstable to PH active liquids, especially acids. When acid (vinegar, fruit juice, wine, etc.) or high-alkaline detergent falls on polished marble, they dissect marble at contact area.
After that the corrosion remains on surface, which look like watermarks or a ring. Attempts to remove such “stains” with stain removers will be a waste of time, as these are not stains, but corrosion marks and they can be eliminated only by countertop re-polishing.
