Knowing how to clean stone countertops properly is the single most important thing you can do to protect your investment. Natural stone is beautiful, durable, and adds significant value to your home, but it is also sensitive to the wrong cleaning products. The acidic cleaner that works perfectly on tile can permanently etch your marble. The granite sealer that protects your kitchen island would damage soapstone. Each stone type demands a specific care approach.
With 30 years of experience helping homeowners maintain their surfaces, we have seen every cleaning mistake in the book and the expensive damage that follows. This guide covers daily cleaning routines, deep cleaning methods, stain removal techniques, and sealing schedules for the four most common stone countertop materials.

General Rules for All Stone Countertops
Before diving into stone-specific instructions, here are the universal rules for how to clean stone countertops regardless of the material:
- Always use pH-neutral cleaners. Stone is sensitive to both acidic and alkaline products. A pH of 7 is ideal. Specialty stone cleaners are formulated to hit this target.
- Wipe up spills immediately. Even sealed stone can stain if liquids sit long enough. Acidic substances like wine, citrus juice, and vinegar are especially dangerous on marble and limestone.
- Use soft cloths only. Microfiber cloths and soft sponges are safe. Avoid abrasive scrub pads, steel wool, and scouring powders that can scratch polished surfaces.
- Skip the DIY cleaning hacks. Vinegar, lemon juice, baking soda paste, and bleach are all commonly recommended online and are all capable of damaging natural stone.
- Use coasters and trivets. Protect the surface from water rings, heat marks, and acidic drink condensation.
- Dry the surface after cleaning. Standing water, even clean water, can leave mineral deposits and water spots on polished stone.
How to Clean Granite Countertops
Granite is the most forgiving of the common natural stones, but it still requires proper care. Understanding how to clean stone countertops starts with knowing that granite is an igneous rock with a relatively tight grain structure that resists staining better than marble or limestone.
Daily cleaning:
- Wipe down the surface with a soft microfiber cloth dampened with warm water
- For light grease or food residue, add a few drops of mild dish soap (pH-neutral like Dawn Free and Clear) to the water
- Wipe in a circular motion, covering the entire surface
- Rinse the cloth with clean water and wipe again to remove any soap residue
- Dry with a clean microfiber cloth to prevent water spots
Weekly deep cleaning:
- Spray the entire counter with a granite-specific cleaner like Granite Gold, StoneTech, or Method Daily Granite
- Let the cleaner sit for 30 seconds to a minute
- Wipe with a clean microfiber cloth using overlapping strokes
- Buff dry with a separate clean cloth for a streak-free shine
Disinfecting granite: If you need to sanitize your granite countertops, use a 50/50 mixture of isopropyl alcohol and water in a spray bottle. Spray the surface, let it sit for three to five minutes, then wipe dry. This kills bacteria without damaging the stone or its seal. Avoid hydrogen peroxide on darker granites as it can lighten the stone.
How to Clean Marble Countertops
Marble is the most delicate of the common countertop stones and requires the most careful cleaning approach. Marble is a metamorphic rock composed primarily of calcium carbonate, which reacts with acids. Even mildly acidic substances cause etching, which appears as dull, lighter spots on the polished surface.
Daily cleaning:
- Use only warm water and a soft cloth for daily wipe-downs
- If soap is needed, use a stone-specific marble cleaner or a tiny amount of pH-neutral dish soap, heavily diluted
- Never spray cleaners directly on marble. Apply the cleaner to the cloth instead to control the amount
- Dry immediately and thoroughly after every cleaning
Dealing with etching: Etching is not a stain. It is a chemical reaction that removes a thin layer of the polished surface. Minor etching on polished marble can sometimes be buffed out using a marble polishing powder like MB Stone Care Marble Polishing Powder. Apply the powder to the damp etch mark, buff with a soft cloth in a circular motion for one to two minutes, and rinse clean. Deep etching requires professional honing and polishing.
Critical warnings for marble:
- Never use vinegar, lemon juice, or any citrus-based cleaner
- Never use bathroom cleaners, tub and tile cleaners, or grout cleaners on marble
- Never use bleach or ammonia
- Wipe up acidic spills like wine, coffee, tomato sauce, and citrus juice within seconds, not minutes
- Always use cutting boards. Acidic food juices will etch marble on contact.
How to Clean Quartzite Countertops
Quartzite is a natural metamorphic stone that is significantly harder than marble and granite, making it one of the most durable countertop options. Do not confuse quartzite (a natural stone) with quartz (an engineered product). Knowing how to clean stone countertops made of quartzite is straightforward since the stone is very resilient.
Daily cleaning:
- Wipe with warm water and a soft microfiber cloth
- For heavier cleaning, use a pH-neutral stone cleaner or a few drops of mild dish soap in warm water
- Quartzite tolerates slightly more cleaning product than marble, but pH-neutral remains the safest choice
- Dry the surface after cleaning to maintain the polish
Deep cleaning: Quartzite handles deeper cleaning well. A stone-specific degreaser can be used on stubborn grease spots. Apply, let sit for a few minutes, and wipe clean. For hard water buildup, use a stone-safe hard water remover rather than vinegar.
Important notes:
- Despite its hardness, quartzite is still porous and requires sealing
- Some stones sold as quartzite are actually marble or dolomite. Perform a lemon juice test on an inconspicuous area before using any cleaning products. If the stone etches from a drop of lemon juice, it is likely marble mislabeled as quartzite and should be cleaned accordingly.
- Quartzite resists scratching better than granite but can still be scratched by abrasive cleaners
How to Clean Soapstone Countertops
Soapstone is a unique natural stone that behaves very differently from granite or marble. It is non-porous, does not require sealing, and is naturally resistant to chemicals and bacteria. However, it is softer than other countertop stones and scratches more easily.
Daily cleaning:
- Wipe with warm water and a soft cloth. Soapstone is highly chemical-resistant, so even slightly acidic or alkaline cleaners will not damage it.
- Mild dish soap works perfectly for everyday cleaning
- For disinfecting, soapstone can handle diluted bleach, hydrogen peroxide, and most household cleaners without damage. This is a significant advantage over other natural stones.
Scratch maintenance: Soapstone will scratch with regular use. This is normal and part of the stone’s character. To minimize the appearance of scratches, apply mineral oil to the surface every few weeks. The oil darkens the stone to its eventual patina color, making light scratches blend in. Deeper scratches can be sanded out with fine-grit sandpaper (220 to 400 grit), then oiled.
Oil treatment: Unlike sealing, oiling soapstone is purely cosmetic. It accelerates the natural darkening process that occurs over time. Fresh soapstone is light gray. With oil or natural use, it gradually darkens to a deep charcoal. Some homeowners oil the entire surface for a uniform dark appearance, while others let it darken naturally for a more varied look.
Stain Removal for Stone Countertops
Even with careful daily cleaning, stains can happen. Here is how to clean stone countertops when standard methods are not enough:
Oil-based stains (cooking oil, grease, cosmetics): Create a poultice by mixing baking soda with water to form a thick paste (the consistency of peanut butter). Spread the poultice over the stain about 1/4 inch thick, cover with plastic wrap, and tape the edges. Let it sit for 24 to 48 hours. The poultice draws the oil out of the stone as it dries. Remove, rinse the area, and repeat if necessary.
Organic stains (coffee, tea, wine, fruit juice): For granite and quartzite, make a poultice with baking soda and hydrogen peroxide (12 percent solution). Apply the same way as the oil-based poultice. For marble, use baking soda and water only since hydrogen peroxide can lighten some marbles.
Water stains and rings: Often these are not actual stains but mineral deposits from hard water. Use a stone-safe hard water remover or make a paste of baking soda and water, apply to the ring, cover, and let dry. For stubborn rings on granite, superfine steel wool (0000 grade) can be used very gently, but never on marble or polished quartzite.
Rust stains: Rust requires a poultice made with a rust-removing agent specifically formulated for natural stone. Do not use standard rust removers from the hardware store as they contain acids that will damage most stone. Products like StoneTech Rust Remover are designed for this purpose.
Ink and dye stains: On light-colored granite and quartzite, a poultice with hydrogen peroxide may work. On darker stones, use lacquer thinner or acetone applied with a soft cloth. Test in an inconspicuous area first.
Sealing Stone Countertops
Sealing is a critical part of understanding how to clean stone countertops because a properly sealed surface is dramatically easier to maintain and more resistant to staining.
Which stones need sealing:
- Granite: Yes. Seal every 1 to 2 years. Some very dense granites like Absolute Black may not need sealing.
- Marble: Yes. Seal every 6 to 12 months due to higher porosity.
- Quartzite: Yes. Seal every 1 to 2 years. Some very dense quartzites absorb minimal sealer.
- Soapstone: No. Soapstone is non-porous and does not accept sealer. Oil is applied cosmetically but does not provide a protective seal.
How to test if your stone needs resealing: Place a few drops of water on the surface. Wait 10 to 15 minutes. If the water absorbs and darkens the stone, it is time to reseal. If the water beads on the surface, the existing seal is still effective.
How to seal stone countertops:
- Clean the countertop thoroughly and let it dry completely (at least two hours)
- Apply a quality impregnating sealer (we recommend StoneTech BulletProof, Miracle 511, or Granite Gold Sealer) with a clean cloth or foam applicator
- Allow the sealer to penetrate for the time specified on the product label, usually 15 to 30 minutes
- Wipe off all excess sealer with a clean dry cloth. Leaving excess sealer on the surface can cause a hazy film.
- Apply a second coat following the same process
- Allow 24 hours of curing time before resuming normal use
Products to Never Use on Stone
These products cause immediate or cumulative damage to natural stone countertops:
- Vinegar: Acidic. Etches marble, travertine, and limestone instantly. Can dull granite finishes over time.
- Lemon juice and citrus cleaners: Acidic. Same etching risk as vinegar.
- Bleach: Can discolor stone and degrade sealers. Safe only on soapstone.
- Ammonia and ammonia-based cleaners: Can strip sealers and dull finishes with repeated use.
- Bathroom and tile cleaners: Typically acidic or highly alkaline. Formulated for ceramic, not natural stone.
- Abrasive cleaners (Comet, Ajax, Soft Scrub): Scratch polished stone surfaces.
- Generic multi-surface sprays: Many contain citric acid or other ingredients that damage stone. Unless the label specifically says stone-safe, do not use it.
- Magic Eraser sponges: These are micro-abrasive and can dull polished stone surfaces with repeated use.
Daily Care Routine
Here is the daily routine we recommend for maintaining any stone countertop:
- Morning: Quick wipe-down with a damp microfiber cloth to remove overnight dust and any dried spills from the evening before
- After cooking: Clean the entire prep and cooking area with a stone-safe cleaner or warm water with a drop of pH-neutral dish soap. Pay attention to areas around the stove and sink where grease and food particles accumulate.
- Spills: Blot immediately with a clean dry cloth. Do not wipe, as this can spread the liquid. For acidic spills on marble, speed matters. Seconds count.
- Evening: Final wipe-down with warm water and a clean cloth. Dry the surface, especially around the sink and faucet areas where water tends to pool.
- Weekly: Use a dedicated stone cleaner for a more thorough cleaning. Inspect the surface for any developing stains or dull spots that might need attention.
This routine takes less than five minutes per day and dramatically extends the life and beauty of your stone countertops. Consistency matters far more than intensity when it comes to stone care.
Frequently Asked Questions
Can I use Clorox wipes on stone countertops?
No. Clorox wipes and similar disinfecting wipes contain citric acid and other chemicals that can etch marble and degrade the sealer on granite and quartzite. For disinfecting stone countertops, use a 50/50 isopropyl alcohol and water spray, or a stone-specific disinfecting cleaner.
How often should I seal my stone countertops?
Granite and quartzite should be sealed every one to two years. Marble should be sealed every six to twelve months due to its higher porosity. Soapstone does not require sealing. The water drop test described in the sealing section above is the best way to determine if your specific countertop needs resealing.
Can I use baking soda on stone countertops?
Baking soda is generally safe for stone countertops when used as a poultice paste for stain removal. However, do not use it as an abrasive scrub on polished surfaces as it can cause micro-scratching over time. For daily cleaning, stick to pH-neutral liquid cleaners rather than abrasive powders.
Why does my granite countertop look dull?
Dull granite is typically caused by soap residue buildup, degraded sealer, hard water mineral deposits, or using the wrong cleaning products over time. Clean with a stone-specific cleaner to remove buildup, reseal the surface, and switch to appropriate cleaning products. For severe dullness, professional polishing may be needed to restore the shine.
Is Dawn dish soap safe for stone countertops?
Dawn Free and Clear (the unscented, dye-free version) is safe for occasional use on granite and quartzite when heavily diluted, just a few drops per quart of water. However, regular Dawn with added fragrances and dyes can leave residue that dulls the surface over time. For daily cleaning, a dedicated stone cleaner is always the better choice.
