Sometimes, people confuse a stain from an etch mark. Before you use a stone sealer to prevent the mark, read about what is an etch mark and how is it different from a stain.

What is an Etch Mark?

An etch mark can be severe or mild depending upon the chemical reaction occurring in the stone due to acidic spills like wine, lemon, aerated beverages, acidic fruits like tomatoes, or ammonia. Some acidic household cleaners also cause etching marks. These marks cannot be fixed by simple materials available on the Big Box Stores. These harsh chemicals ruin the stone from within and make it dull-looking from the top. There are some stones which are etch-proof, but yet, they don’t provide a 100% guarantee against etching marks.

How to Tell the Difference Between Staining and Etching?

If you are confused whether it is a stain or an etch mark, you need to take a closer look at the mark. The etching is a kind of physical damage. Etch marks when seen at the right angle, appear as a sign of physical damage with visible dulling. These are often light or whitish in color. The etch mark gets more severe if the harsh substance remains on the stone for longer.

Staining, on the other hand, occurs when the pores of the natural stone absorb the liquid spilt on its surface. These stains are generally in the colour of the liquid and they do not affect the surface finish or the sheen of the stone.

What Happens when a Stain is Formed on the Etched Surface?

When coffee or tomato juice is spilt on an etched surface of your natural stone, it absorbs the liquid more easily and leaves a colored stain. The etch mark has already been formed with an acidic spill and the surface becomes easily susceptible to staining.
