Etching is surface damage caused by acidic substances like lemon juice, wine, or vinegar eating into the stone’s finish. It appears as dull, lighter spots on polished surfaces. Staining is when a substance absorbs into the porous stone, leaving a darker discoloration. Etching requires professional honing and polishing to remove, while stains can sometimes be lifted with poultices or professional cleaning. Both are common in NYC & Long Island homes, but they need different treatments.
No. Vinegar, lemon juice, and acidic cleaners will permanently damage marble, travertine, limestone, and onyx. These stones are calcium-based, and acids eat into the surface, causing etching that dulls the finish. Even diluted vinegar will cause damage over time. Stick with pH-neutral stone cleaners or a drop of mild dish soap with water. If you’ve already used acidic cleaners and notice dull spots, we can fix the damage with professional restoration.
Stone restoration typically costs 50-75% less than replacement. In the NYC & Long Island area, professional restoration for kitchen countertops runs $800-$2,500, while replacement costs $3,000-$8,000 or more depending on the stone type. Minor repairs like chip filling cost $25-75 each. Restoration also takes 1-2 days versus weeks for replacement, with no demolition mess or downtime. Unless the stone is severely damaged or you want a completely different look, restoration makes more financial sense.
Call us when you’re dealing with deep scratches, widespread etching, chipped edges, cracks, or dull surfaces that won’t respond to cleaning. If your stone has lost its shine despite proper maintenance, or if you’re seeing extensive staining, DIY methods won’t fix it and might make it worse. Professional-grade equipment and expertise are needed for honing, polishing, and structural repairs. For routine cleaning and light maintenance, DIY is fine—but restoration work requires specialized knowledge.
Professional stone restoration follows a multi-step process. First, any damaged tiles are repaired or replaced. Then grinding removes deep scratches and levels uneven surfaces. Honing smooths the stone with progressively finer diamond abrasives, removing scratches and etching. Polishing brings back the shine using specialized compounds. Finally, sealing protects the restored surface. We use water to minimize dust, and most residential floors are completed in 1-2 days. The result is stone that looks factory-fresh.
Not all stone requires sealing, but most benefit from it. Porous stones like marble, travertine, and limestone definitely need sealing to resist stains. Many granites are dense and pre-sealed at the factory, though lighter-colored granites may need periodic resealing. Soapstone doesn’t require sealing but can be treated with mineral oil for color enhancement. The water absorption test tells you what you need—if water soaks in quickly, sealing is necessary. When in doubt, seal for protection.
Yes, wine stains can usually be removed from marble, though it depends on how long they’ve been there. Fresh spills should be blotted immediately—never wiped, as that spreads the stain. For set-in wine stains, we use poultices or specialized stain removal techniques that draw the stain out of the porous stone. If the wine also caused etching (common with red wine), the surface will need honing and polishing after stain removal. Quick action gives the best results.
