Etch marks or etching in general happens when acidic substances including a few of the cleaning products come into contact with a natural stone surface such as marble or travertine or limestone. Examples of acidic substances are alcoholic beverages, lemon, vinegar, wines, coffee, orange juice, etc. The etched area looks more dull than the others due to the chemical reaction between the minerals of the natural stone and the spilled substance.
In general to remove etch marks, spottings, minor stains, water rings, the countertop surface or damaged natural stone surface area has to be sanded through a process called “Diamond sanding” that is performed using water. It is more practical to hire a professional natural stone care company to perform the restoration process as sanding does require experience and use of proper tools and material.
The natural stone care technician will use multiple sanding levels starting with a lower grit to remove the etch and minor stain marks then use higher grit levels to smooth the surface area prior to the polishing process. Below are the steps stated FYI in a simple manner yet require deeper understanding and experience
● Surface sanding (diamond sanding or wet sanding) different grit levels
● Cleaning with a neutral PH solution
● Sealing and buffing to ensure consistency and to remove excess sealer
