Many stones classified as “quartzites” have marble properties (calcite) in them. This does get confusing for slab suppliers, fabricators, and then the homeowners as well. Therefore, homeowners are getting a beautiful stone that still may etch in some areas, but not others. In these cases, if the stone has been etched, it is typically happening in the marble-like (calcite) areas and thus our Etch Remover will work to repair these areas.
