Granite scratches almost always live in the polished sealer, not the stone itself — buff the mark with 2000 to 3000 grit diamond polishing pads, clean the area, then reseal it, and a surface scratch disappears in under 30 minutes. A scratch that catches your fingernail and stays visible after buffing has gone into the stone and needs a professional re-polish, not a DIY fix.
- Granite rates 6 to 7 on the Mohs hardness scale, so most visible marks sit in the sealer, not the stone.
- How to remove scratches from granite countertops starts with 2000-3000 grit diamond polishing pads and a fresh coat of sealer.

Why this matters
Granite is one of the hardest countertop materials sold in 2026, which is exactly why most homeowners panic over a mark that isn't really a scratch. Steel wool, a dropped skillet, or a knife dragged flat across the surface usually scuffs the sealer topcoat, not the mineral crystal underneath. Knowing the difference saves you from replacing a slab that only needed a buff and reseal.
Routine care prevents most of this in the first place — the granite care guide covers the resealing schedule that keeps the surface layer thick enough to absorb daily wear instead of showing it.
How do you remove scratches from granite countertops?
Work through these steps in order before assuming the slab needs replacing:
- Clean the area with mild dish soap and water, then dry it completely — trapped grit scratches worse if you sand over it.
- Wet-sand the mark with a 400-grit diamond polishing pad if the scratch is visible under raking light, working in small circles.
- Step up through the grits — 800, then 1500, then 3000 — to restore the factory-level shine.
- Apply a penetrating sealer once the surface is completely dust-free; skipping this step leaves the repaired spot porous and prone to staining.
- Buff with a soft microfiber cloth to blend the repaired area into the surrounding polish so it doesn't read as a patch.
The whole process takes under an hour for a single scratch. If the mark is still visible after the 3000-grit pass, it's not in the sealer — it's in the stone, and hand-buffing won't fix it.
Light scratches: buff with fine-grit polishing pads
Most "scratches" homeowners report in 2026 are actually hairline scuffs in the polished resin sealer that sits on top of the granite. These respond well to the grit progression above because you're only removing a microscopically thin layer, not reshaping the stone.
A quick test: wet the scratch with a few drops of water. If it disappears or fades noticeably, it's sitting in the sealer and the buffing steps will clear it. Verdict: buff-and-reseal wins for any scratch that fades when wet — no need to call anyone.
One caution: dark granite (absolute black, star galaxy) shows sanding swirl marks more than light granite (Alaska white, Santa Cecilia), so work slowly and check the sheen under direct light between grit changes.
Deep gouges: call a professional fabricator
A scratch that stays visible dry, catches a fingernail when you drag it across, or runs in a straight line deeper than a hairline has gone into the crystal structure of the stone. Home sanding at this depth flattens a visible divot into the surface, and mismatched polish creates a duller patch that's more noticeable than the original scratch.
Professional re-polishing uses diamond-impregnated pads on a variable-speed polisher and matches the exact sheen level of the original fabrication — something a handheld pad can't replicate consistently. If you're not sure which category your scratch falls into, a countertop fabricator can tell you in minutes whether it's a five-minute buff or a shop repair. Verdict: DIY for hairline sealer scuffs, professional repair for anything visible dry — don't gamble a slab you paid for on a $12 sanding kit.

Why granite countertops scratch
Granite resists scratching better than almost any other kitchen surface, but a few habits cause most of the marks fabricators see:
- Cutting directly on the stone instead of using a board — knife blades don't scratch granite itself, but they dull the sealer fast.
- Dragging cast iron or ceramic cookware across the surface instead of lifting it.
- Steel wool or scouring pads used for cleanup, which are abrasive enough to scuff sealer over repeated use.
- Grit trapped under cutting boards or appliances that gets ground into the surface when items slide.
- Kids and pets in the kitchen — busy households see more incidental contact from toys, dishes, and claws than quieter ones, which is worth factoring into material choice for homes with kids and pets.
- Overdue resealing, which thins the protective topcoat and makes the surface more vulnerable to everyday wear.
Does toothpaste remove scratches from granite countertops?
No — toothpaste is too abrasive for the fine polish granite needs and too coarse to match a 3000-grit finish, so it often leaves the spot duller than before. It's a myth that persists online but doesn't hold up against the actual grit progression a repair requires.
Can you use a Magic Eraser on granite scratches?
A Magic Eraser is melamine foam, mildly abrasive enough to lift grime but not fine enough to remove an actual scratch. Repeated use can dull the sealer's sheen over time, so save it for cleanup, not repair.
How do you know if a granite scratch is only in the sealer?
Wet the mark with water — if it fades or disappears, it's sitting in the sealer layer and will respond to buffing. If it's still visible wet and catches a fingernail, it's in the stone and needs professional attention.
FAQ
How do you remove scratches from granite countertops at home?
Buff the mark with diamond polishing pads working from 400 grit up to 3000 grit, then reseal the area — this fixes scratches sitting in the sealer, which is most of them. Deep gouges visible dry need professional re-polishing instead.
Can granite actually scratch?
Granite rates 6 to 7 on the Mohs hardness scale, hard enough that knives and most kitchen tools can’t scratch the stone itself. What homeowners usually see is wear in the thin polished sealer layer on top.
Does toothpaste remove scratches from granite countertops?
No, toothpaste isn’t fine enough to match granite’s polished finish and often leaves the spot duller. Use graduated diamond polishing pads instead of household abrasives.
How much does it cost to repair a scratched granite countertop?
Light sealer scratches cost nothing to fix with a DIY buffing kit, while deep gouges require a professional fabricator visit priced per job. Ask a fabricator for a quote once you’ve confirmed the scratch goes into the stone.
How often should you reseal granite to prevent scratching?
Most granite countertops need resealing once a year, though high-use kitchens may need it twice. A thinner sealer layer wears through faster and exposes the surface to more visible scuffing.
Is granite or quartz more scratch resistant?
Granite is a natural stone that resists scratching better than most engineered quartz surfaces because of its higher mineral hardness. Quartz is engineered for consistency and stain resistance but can show scratches from knives more readily than granite.
Can a Magic Eraser damage granite countertops?
A Magic Eraser won’t cause deep damage but repeated use can dull the polished sealer over time. It’s fine for occasional grime removal, not for scratch repair.
When should you call a professional instead of buffing a scratch yourself?
Call a fabricator when the scratch is visible after the surface is dry and catches a fingernail, since that means it’s gone into the stone. DIY buffing kits only resolve scratches sitting in the sealer layer.
One last thing
Most of what homeowners call a "granite scratch" in 2026 is actually etching from an acidic spill or dulled sealer from steel wool — genuine scratches into the mineral itself are rare given granite's 6-7 Mohs rating. Test with water before you reach for sandpaper; you'll save yourself an unnecessary repair more often than not.
