DEFINITION: Etch removal is the process of restoring the shine and surface finish of natural stone surfaces that have been damaged by chemical corrosion. Etching occurs when acidic substances such as lemon juice, vinegar, or certain cleaning products come in contact with the stone surface, resulting in a dull or discolored appearance. Etch removal typically involves the use of specialized abrasives or polishing compounds that are applied to the surface of the stone to remove the damaged layer and restore the original finish. The process may also involve grinding and honing the stone surface to achieve a smooth and even finish. Etch removal is typically performed by trained professionals, as it requires knowledge of the type of stone and the appropriate chemicals and techniques to use without causing further damage. The result is a restored natural stone surface that looks like new again.
