The etch mark is a surface damage in the form of a dull mark on natural stone that contains calcium carbonate. Coffee, red wine, oranges, lemons, vinegar, grapefruits, and acidic cleaning products are all examples of substances that can result in etching when in contact with a natural stone surface. When such substances (pH<7) come into prolonged contact with a natural stone, they corrode the stone and change its texture. Etch mark is not the same as the stain. Etch marks are lighter color than the stone, while stains have darker shades.

Eliminating Etch Marks

The most common mistake people make while trying to remove etch marks, is using conventional cleaning products. Such products can actually make etch marks worse. You should always use a pH-neutral cleaner when cleaning stone.

To remove minor etch marks from polished surfaces, apply a stone polishing powder and then buff the area until the mark disappears. If the etch mark is deep, you will need a professional help to remove it the proper way. NOVA Stone Care technicians are trained to remove etch marks without damaging rest of the surface. We get rid of etch marks by honing, polishing and sealing the surfaces. They say actions speak louder than words. Why don’t you take a look at before and after pictures to judge yourself?
