Esteemed for its solid strength and unmistakable beauty, granite never goes out of style. Granite is not, however, invulnerable to damage. Although granite is resistant to etching, acids and other corrosive agents may etch its surface. Acidic foods such as lemons or tomato sauce can discolour granite and mar its beauty. Fortunately, homeowners can repair most mildly etched granite surfaces themselves. Severely etched granite, however, may require professional attention. Promptly fix etched granite to restore its original beauty.
Clean the etched granite thoroughly before repairing it. Pour two drops of stone soap into a tub containing 1 gallon of water. Mix the stone soap solution thoroughly.
Wet a rag in the stone soap solution. Wipe the etched granite with the soapy rag, removing all grime and residue.
Dampen another rag in water. Wipe the rag over the granite surface to rinse away soapsuds and detached gunk.
Wipe the wet granite with a dry towel. Thoroughly dry the etched granite surface.
Focus on removing the etch marks. Sprinkle 28.4gr granite polishing powder onto the etched granite. Pour 28.4gr water onto the polishing powder.
Attach a felt buffing pad to a low-speed power drill, following the drill manufacturer's directions. Glide the power drill in circular motions over the paste-coated granite until the etch marks disappear. Keep the granite coated with the powdery paste as you buff it.
Wipe the powdery paste residue off the granite with a clean rag.
Polish the granite to remove any lingering marks and add shine. Apply 1 tbsp stone polishing compound to the granite surface.
Buff the granite with the low-speed power drill and attached buffing pad until the polishing compound residue dissolves.
Never clean granite with acid-based cleaners, as additional etching may occur. Spot-test the granite polishing powder and stone polishing compound on the granite to avoid any damage.
