What Is Acid Etching In Natural Stones

acid etching.jpg

In the stone world, normally, acid etching is known as the surface erosion of natural stone.


Marble, travertine, limestone and onyx will react to acidic foods (i.e. lemons or tomatoes) and acidic liquids(i.e. some cleaners or acid rain). This reaction will result in a dulling in surface sheen and change in texture, otherwise referred to as "acid etching".

1-Minimally sensitive

This material is not sensitive to acids. 

It will not acid etch or loses its surface sheen when exposed to acidic foods.

2- Moderately sensitive

This material is moderately sensitive to acids. 

Generally, acid etching will be less visible on lighter stones and honed surfaces.

3- Highly sensitive

This material is highly sensitive to acids.

Acid etching will be highly visible on this material when exposed to acidic foods such as lemons or tomatoes. Do not use this material on kitchen countertop applications where acid etching is a concern. If acid etching is a concern, select a minimally sensitive material.

helpful tips

- If etching is a concern, select a material with a minimally sensitive acid resistance rating, such as a quartzite.

- If etching is a concern, specify a light, honed surface which diminishes the visibility of acid etching.

- To remove an acid stain from a polished stone surface, use Fila Marble Restorer.
