How to Fix an Etched Limestone Counter

Limestone countertops’ deep shades and random fossil patterns add an exquisite touch to bathrooms and kitchens. As a softer natural stone, however, limestone is vulnerable etching from acidic foods and household cleaning solutions. Unsealed limestone countertops are more likely to become etched than sealed limestone. Etch marks typically appear as pale discoloration on limestone, and more prominent marks often indicate more severe etching. Promptly fix an etched limestone countertop to restore its appearance.

1/4 teaspoon neutral detergent
Cleaning pail
Spoon
3 cloths
Stone polishing powder
Lambswool buffing pad
Low-speed power drill
Soft, clean towel
Nonabrasive stone polishing cream
Microfiber pad

Instructions

- 1
  Clean the etched section of the limestone countertop first to remove any residue or grime particles. Begin by pouring 1/4 teaspoon of neutral detergent into a cleaning pail. Stir in 1 quart of water using a spoon.
- 2
  Moisten a cloth in the solution. Wipe the etched limestone countertop until it’s completely clean.
- 3
  Dampen a fresh cloth with water. Wipe the limestone to rinse off soapy grime. Leave the limestone wet after rinsing the countertop.
- 4
  Sprinkle a stone polishing powder safe for use on limestone evenly onto the wet etch mark, and then lightly moisten the powder with water to form a thin paste.
- 5
  Fit a lambswool buffing pad onto a low-speed power drill. Turn the drill on a low speed, and then gently guide the buffing pad over the etched limestone.
- 6
  Continue buffing the etched stone surface until the discolored mark disappears. Add more polishing powder to the etched limestone, if necessary, and always keep the powder slightly moist to prevent scratching the limestone.
- 7
  Dampen a clean cloth with water. Wipe the powdery residue off the countertop’s surface, thoroughly rinsing the stone.
- 8
  Dry the wet limestone surface with a soft, clean towel.
- 9
  Squeeze a quarter-size dollop of nonabrasive stone polishing cream onto a microfiber pad. Rub the pad over the previously etched limestone in circular motions to restore luster. Thoroughly buff the cream into the limestone.
