Granite countertops need daily wiping with a pH-neutral soap, a yearly reseal, and zero contact with vinegar, bleach, or ammonia — that's the entire routine, and skipping any one of those three steps is what actually causes staining and dulling over time. The part most homeowners miss isn't the daily cleaning, it's the seal: a granite countertop with a worn sealant absorbs oil and wine within minutes, while a properly sealed one shrugs off the same spill for hours. In 2026, that difference is still the single biggest factor separating granite that looks new after a decade from granite that looks tired after two years.
- Daily care for granite countertops is pH-neutral soap, a soft cloth, and immediate spill wipe-up — nothing acidic, ever.
- Reseal granite countertops once a year on average; run the water-bead test first to check if it’s due sooner.
- Vinegar, bleach, and ammonia strip granite sealant and etch the stone — skip them even for tough stains.
- Soares Stone recommends resealing New England kitchens before humid summers hit, when moisture exposure is highest.
- Granite is heat- and scratch-resistant day to day, but it still needs a trivet under cast iron and direct flame.
Why granite care matters more than most homeowners think
Granite is a natural stone, not a manufactured surface like quartz, which means every slab has its own porosity and its own sealant needs. A slab that isn't resealed on schedule starts absorbing liquids into microscopic pores instead of letting them sit on top where a cloth can catch them.
That's the mechanism behind almost every granite stain story you've heard: it's rarely the countertop's fault, it's a missed reseal or an acidic cleaner that etched the surface first. Soares Stone fabricates and installs granite, marble, quartz, and quartzite across New England kitchens, and the care routine below is the same one that keeps a freshly installed slab looking that way for years, not months.
How do you care for granite countertops?
The full routine breaks into three habits, done at three different frequencies:
- Daily — wipe with warm water and a few drops of dish soap or a dedicated stone cleaner, dry with a soft cloth, and blot spills (wine, coffee, citrus, oil) the moment they happen.
- Weekly — do a full wipe-down of the entire surface, including edges and around the sink, since grime builds up fastest where water pools.
- Annually — reseal the granite and run a water-bead test to confirm the seal is holding.
| Task | Frequency | What to use | What to avoid |
|---|---|---|---|
| Daily wipe-down | Every day | Mild dish soap + warm water | Vinegar, lemon, bleach |
| Spill cleanup | Immediately | Soft cloth, blot don't rub | Scouring pads |
| Deep clean | Weekly | Granite-specific cleaner | Ammonia-based glass cleaner |
| Resealing | Once a year | Impregnating stone sealer | Skipping the water test |
| Heat protection | Every use | Trivet or hot pad | Direct pan-to-stone contact |
Sealing granite countertops: the water-bead test
Most granite installed today is sealed at fabrication, but that seal wears down with use, and once it's gone, the stone is exposed. Run this test once a year, ideally in spring before the humid New England summer sets in:
- Pour a small amount of water on the countertop and let it sit for 15-20 minutes.
- If the water beads up and sits on the surface, the seal is still holding.
- If it soaks in and darkens the stone, it's time to reseal.
Resealing itself is a straightforward DIY task with an impregnating stone sealer applied in a thin coat, left to absorb, then wiped clean of excess before it cures. Homeowners who skip this step are the ones who show up a year later asking why their granite suddenly stains from a glass of red wine that never used to leave a mark.
Removing stains without damaging the sealant
Oil-based stains (cooking grease, hand lotion) darken the stone, while acidic stains (wine, citrus, tomato sauce) can dull the polish if left too long. Both respond to the same basic fix: a poultice of baking soda and water, spread over the stain, covered in plastic wrap, and left overnight before wiping clean.
Hard water spots around the sink respond to the same poultice method — never to vinegar, which is acidic enough to etch granite's calcium content over repeated use. If a stain doesn't lift after two poultice applications, it's a job for a professional, not a stronger chemical.
Why granite care needs vary from kitchen to kitchen
Not every granite countertop needs the exact same attention. A few things shift the routine:
- Color and density — darker granites (like Absolute Black) hide etching better than lighter, more porous colors like Kashmir White.
- Sealant quality at install — a professionally applied impregnating sealer lasts longer than a big-box store's basic topical coat.
- Kitchen usage — a countertop that sees daily cooking and wine pours needs more frequent spot-checks than a guest bathroom vanity.
- Cutting habits — chopping directly on the stone dulls knives and can scratch the polish, even though granite resists most everyday scratches.
- Climate and humidity — New England's humid summers and dry winters both stress sealant faster than a stable indoor climate would.
- Sink and faucet placement — countertops with an undermount sink near the edge see more standing water and need more frequent drying.
Homeowners weighing granite against other options for a busy household should look at how it compares directly against low-maintenance countertop materials before committing to a slab.
How often should granite countertops be resealed?
Granite countertops should be resealed once a year on average, though some dense, dark granites can go longer between reseals. The safest approach is skipping the calendar guess entirely and running the water-bead test each spring to confirm whether the seal is still active.
Can you use vinegar or Windex on granite countertops?
No — vinegar and ammonia-based glass cleaners like Windex both strip granite's sealant and can etch the stone's surface over repeated use. Stick to a pH-neutral dish soap or a cleaner labeled specifically for natural stone.
Is granite countertop maintenance different from quartz?
Granite needs annual resealing because it's porous, while quartz is engineered and non-porous, so it never needs sealing at all. That maintenance gap is one of the main reasons homeowners comparing the two research how to choose between quartz and quartzite countertops before finalizing a kitchen remodel.
Does granite scratch or burn easily?
Granite resists both scratching and heat far better than laminate or solid-surface countertops, but it isn't indestructible. A trivet under cast iron and a cutting board for prep work keep the polish intact for the life of the countertop — households with active kids or pets often ask about this directly on the best countertops for homes with kids and pets guide.

FAQ
How do you clean granite countertops daily?
Clean granite countertops daily with warm water, a few drops of mild dish soap, and a soft cloth, then dry the surface to prevent water spots. Avoid paper towels with rough texture and any cleaner containing vinegar, bleach, or ammonia.
How often should you reseal granite countertops?
Reseal granite countertops once a year on average, checking with a water-bead test each spring before assuming it’s due. Denser, darker granites sometimes hold a seal longer than porous, lighter-colored stone.
Can you use vinegar to clean granite countertops?
No, vinegar is acidic enough to etch granite and break down its sealant over repeated use. Use a pH-neutral dish soap or a cleaner made specifically for natural stone instead.
What causes granite countertops to stain?
Granite stains when oil, wine, or acidic liquids sit on an unsealed or worn-sealed surface long enough to absorb into the stone’s pores. Wiping spills immediately and resealing annually prevents most staining before it starts.
Is granite better than quartz for a kitchen?
Granite offers a natural, one-of-a-kind pattern and strong heat resistance, while quartz never needs sealing and resists stains more consistently. The right choice depends on whether you want a natural stone look or lower-maintenance engineered surface.
How do you remove hard water stains from granite?
Remove hard water stains from granite with a baking soda and water poultice left overnight under plastic wrap, then wiped clean. Avoid vinegar-based descalers, which etch the stone’s surface.
Can granite countertops be repaired if scratched or chipped?
Minor scratches on granite typically buff out with a granite polishing compound, but deeper chips need a professional stone repair kit or fabricator visit. Granite resists scratching well day to day, so visible damage usually comes from heavy impact, not normal use.
One last thing
The water-bead test takes two minutes and costs nothing, yet most granite complaints Soares Stone hears trace back to a homeowner who never ran it. Set a calendar reminder for the same week every spring in 2026 and beyond — that single habit prevents more staining than any cleaner on the market.
