Natural stone surfaces like marble, granite, limestone, and travertine are stunning — but they can also be surprisingly sensitive. If your once-perfect countertops or floors are showing strange marks or discoloration, your stone might be trying to tell you something.
Understanding what type of stain you’re seeing — and why it happened — is the first step in restoring your stone and protecting it for the future. Here’s your quick guide to decoding stone stains like a pro.
🟥 1. The Stain: Wine Rings, Juice Circles, Coffee Spots
Looks like: Dull, light patches or dark rings, often with defined edges
Stone Type: Common on marble, limestone, or other calcium-based stones
What it means:
You’re looking at either an etch mark (caused by acidic liquids like wine, juice, vinegar) or a stain (caused by absorption of pigmented liquids).
Treatment:
Etching requires resurfacing or polishing. Stains may need poultice extraction.
Prevention: Use coasters and consider sealing or adding a protective coating like MORE® AntiEtch®.
🟫 2. The Stain: Rusty Orange or Brown Marks
Looks like: Speckled or patchy rust-colored areas
Stone Type: Most common on lighter granites or stones with iron content
What it means:
There may be metal underneath the stone (like fasteners) that’s oxidizing, or water exposure is reacting with minerals inside the stone.
Treatment:
Rust removers specific for stone or deep poultice treatments may help — but severe cases may need restoration.
Prevention: Keep stone dry and sealed, and avoid metal objects sitting wet on the surface.
🟨 3. The Stain: Yellowing or Dull Discoloration
Looks like: A hazy yellow cast, especially in high-traffic areas
Stone Type: Marble, travertine, limestone
What it means:
Trapped moisture, chemical damage, or oxidation is at play. Old waxes and sealers can also yellow over time.
Treatment:
Professional stripping and honing, plus identifying the moisture source.
Prevention: Avoid over-sealing and use breathable products appropriate for natural stone.
🟦 4. The Stain: Water Spots & Mineral Deposits
Looks like: Cloudy white rings or patches, especially near sinks and faucets
Stone Type: All types, especially marble and granite
What it means:
Hard water has left behind calcium and magnesium deposits.
Treatment:
Mild descalers or polishing pads may be needed. Don’t scrub with vinegar — it can etch your stone!
Prevention: Wipe down wet areas and consider a water softener.
5. The Stain: Oily Spots or Greasy Shadows
Looks like: Dark, shadowy patches that linger no matter how much you wipe
Common On: Marble, granite, limestone, and other porous stones
What It Means:
Oils from cooking, hands, lotions, or cosmetics have soaked into the stone’s surface. These stains tend to darken over time and can be tough to remove without the right approach.
