Etching is the physical response of marble when exposed to acids. The physical contact of an acid based liquid (lime juice, lemon juice, salad dressing, wine, citrus fruits juices… etc) on top of marble causes marble to break down. One could never “burn” a hole into the marble but can easily affect a mable’s surface finish. An etch mark looks like a surface “water ring or spot” or a surface spot the is “duller looking: that the rest of the surface. That marble is easily buffed by hand with a fine steel wool, tougher etch marks can be professionally buffed if needed. The integrity of the stone is hardly compromised and sealers sit below the stone’s surface to provide continued protection from staining. A true marble lover’s kitchen will showcase its beautiful etch-markings, evidence of a life well lived and a party well worth having had.
